EUVD-2025-15763

Comprehensive Technical Analysis of EUVD-2025-15763

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified as EUVD-2025-15763 pertains to an "Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')" in the mojoomla WPAMS plugin. This vulnerability allows for PHP Local File Inclusion (LFI), which can lead to privilege escalation. The CVSS Base Score of 9.8 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:

• AV:N - Attack Vector: Network
• AC:L - Attack Complexity: Low
• PR:N - Privileges Required: None
• UI:N - User Interaction: None
• S:U - Scope: Unchanged
• C:H - Confidentiality: High
• I:H - Integrity: High
• A:H - Availability: High

This high score underscores the critical nature of the vulnerability, indicating that it can be easily exploited with severe consequences.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is through network access. An attacker can exploit the improper control of filenames in PHP include/require statements to include and execute arbitrary local files. This can be achieved by manipulating input parameters to include malicious PHP files, leading to code execution on the server.

Potential exploitation methods include:

• Directory Traversal: Attackers can use directory traversal techniques to access files outside the intended directory.
• Code Injection: By including malicious PHP code, attackers can execute arbitrary commands on the server.
• Privilege Escalation: Once code execution is achieved, attackers can escalate privileges to gain higher access levels within the system.

3. Affected Systems and Software Versions

The vulnerability affects the mojoomla WPAMS plugin versions from n/a through 44.0. This means that all versions up to and including 44.0 are susceptible to this vulnerability. Organizations using this plugin within the specified version range are at risk.

4. Recommended Mitigation Strategies

To mitigate this vulnerability, the following strategies are recommended:

• Update to a Patched Version: Ensure that the WPAMS plugin is updated to a version that addresses this vulnerability. If a patch is not available, consider disabling the plugin until a fix is released.
• Input Validation: Implement strict input validation and sanitization to prevent malicious file inclusions.
• Least Privilege Principle: Run the web server and PHP processes with the least privileges necessary to minimize the impact of a successful exploit.
• Web Application Firewalls (WAF): Deploy WAFs to monitor and block suspicious activities, including attempts at directory traversal and code injection.
• Regular Security Audits: Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.

5. Impact on European Cybersecurity Landscape

The impact of this vulnerability on the European cybersecurity landscape is significant. Given the widespread use of WordPress and its plugins, including WPAMS, many organizations and individuals could be affected. The potential for privilege escalation and arbitrary code execution poses a serious risk to data integrity, confidentiality, and availability. This underscores the need for robust cybersecurity measures and continuous monitoring within the European Union.

6. Technical Details for Security Professionals

For security professionals, the following technical details are pertinent:

• Vulnerability Type: PHP Local File Inclusion (LFI)
• Affected Component: mojoomla WPAMS plugin
• Exploitation: Manipulation of include/require statements in PHP to include and execute arbitrary files
• Detection: Monitor for unusual file access patterns, directory traversal attempts, and unexpected code execution
• Mitigation: Implement input validation, use WAFs, apply the principle of least privilege, and ensure timely patching
