EUVD-2025-22140

Comprehensive Technical Analysis of EUVD-2025-22140

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-22140 pertains to an OS Command Injection flaw in Eveo URVE Web Manager version 27.02.2025. The application exposes a /_internal/pc/vpro.php endpoint to unauthenticated users, which directly passes input parameters to the shell_exec() function in PHP. This vulnerability allows an attacker to execute arbitrary OS commands on the server, potentially leading to full system compromise.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates that this vulnerability is critical due to its low attack complexity, lack of required privileges, and the potential for high impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The vulnerability can be exploited without any authentication, making it accessible to any attacker with network access.
• Command Injection: An attacker can inject malicious commands through the input parameter, which are then executed by the server.

Exploitation Methods:

• Direct Command Execution: An attacker can send crafted HTTP requests to the /_internal/pc/vpro.php endpoint with payloads designed to execute OS commands.
• Chaining with CVE-2025-36845: The vulnerability can be chained with CVE-2025-36845, potentially amplifying the impact and allowing for more sophisticated attack scenarios.

3. Affected Systems and Software Versions

Affected Systems:

• Eveo URVE Web Manager version 27.02.2025

Software Versions:

• Any installation of Eveo URVE Web Manager version 27.02.2025 that has not been patched or mitigated against this vulnerability.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest security patches provided by the vendor to address the vulnerability.
• Access Control: Restrict access to the /_internal/pc/vpro.php endpoint to trusted IP addresses or internal networks only.
• Input Validation: Implement strict input validation and sanitization to prevent command injection.

Long-Term Mitigation:

• Code Review: Conduct a thorough code review to identify and remediate similar vulnerabilities.
• Security Training: Educate developers on secure coding practices to prevent future occurrences of command injection vulnerabilities.
• Monitoring: Implement continuous monitoring and logging to detect and respond to suspicious activities.

5. Impact on European Cybersecurity Landscape

The critical nature of this vulnerability poses a significant risk to organizations using Eveo URVE Web Manager within the European Union. Unpatched systems are at high risk of being compromised, leading to potential data breaches, system downtime, and financial losses. The vulnerability underscores the importance of timely patch management and the need for robust cybersecurity measures to protect critical infrastructure.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: /_internal/pc/vpro.php
• Function: shell_exec()
• Input Parameter: Unspecified, but directly passed to shell_exec()

Exploitation Example: An attacker could send a crafted HTTP request to the vulnerable endpoint:

POST /_internal/pc/vpro.php HTTP/1.1
Host: vulnerable-server.com
Content-Type: application/x-www-form-urlencoded

param=;ls -la;

This request would execute the ls -la command on the server, listing directory contents.

Detection:

• Log Analysis: Monitor server logs for unusual command execution patterns.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious network traffic targeting the vulnerable endpoint.
