EUVD-2025-199660

Comprehensive Technical Analysis of EUVD-2025-199660

1. Vulnerability Assessment and Severity Evaluation

The vulnerability in the AI Feeds plugin for WordPress, identified as EUVD-2025-199660 (CVE-2025-13597), is classified as an arbitrary file upload vulnerability. This issue arises due to a missing capability check in the actualizador_git.php file, which allows unauthenticated attackers to download arbitrary GitHub repositories and overwrite plugin files on the affected site's server. The potential for remote code execution (RCE) significantly elevates the severity of this vulnerability.

Severity Evaluation:

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

The high CVSS score indicates a critical vulnerability due to the following factors:

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

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit this vulnerability without needing any credentials.
• Arbitrary File Upload: The lack of capability checks allows attackers to upload malicious files.
• Remote Code Execution (RCE): By overwriting plugin files, attackers can execute arbitrary code on the server.

Exploitation Methods:

• Direct Exploitation: Attackers can directly target the actualizador_git.php file to upload malicious files.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable installations and exploit them en masse.
• Phishing Campaigns: Attackers can lure users to visit malicious sites that exploit this vulnerability.

3. Affected Systems and Software Versions

Affected Software:

• Plugin: AI Feeds
• Versions: All versions up to and including 1.0.11

Affected Systems:

• WordPress Installations: Any WordPress site using the AI Feeds plugin version 1.0.11 or earlier.
• Server Environments: Any server hosting a vulnerable WordPress site, including shared hosting environments.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Plugin: Immediately update the AI Feeds plugin to a version higher than 1.0.11.
• Disable Plugin: If an update is not available, disable the AI Feeds plugin until a patched version is released.
• Monitor Logs: Closely monitor server logs for any suspicious activity related to the actualizador_git.php file.

Long-Term Mitigation:

• Regular Updates: Ensure all plugins and WordPress core are regularly updated.
• Access Controls: Implement strict access controls and capability checks for all plugin files.
• Security Plugins: Use security plugins like Wordfence to monitor and protect against vulnerabilities.
• Web Application Firewall (WAF): Deploy a WAF to block malicious requests targeting known vulnerabilities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to the European cybersecurity landscape, particularly for organizations and individuals using WordPress. The potential for RCE can lead to data breaches, unauthorized access, and service disruptions. Given the widespread use of WordPress, this vulnerability could affect a large number of websites, including those of critical infrastructure and government agencies.

Regulatory Implications:

• GDPR Compliance: Organizations must ensure they comply with GDPR by protecting personal data from unauthorized access.
• Incident Reporting: Organizations must report any data breaches resulting from this vulnerability to relevant authorities within 72 hours.

6. Technical Details for Security Professionals

Vulnerable File:

• File Path: actualizador_git.php
• Vulnerable Code: The missing capability check allows unauthenticated file uploads.

Exploitation Steps:

1. Identify Target: Scan for WordPress sites using the AI Feeds plugin version 1.0.11 or earlier.
2. Craft Payload: Create a malicious payload that exploits the arbitrary file upload vulnerability.
3. Upload Payload: Send a crafted HTTP request to the actualizador_git.php file to upload the payload.
4. Execute Code: Overwrite plugin files with the malicious payload to achieve RCE.

Detection and Response:

• Intrusion Detection Systems (IDS): Configure IDS to detect and alert on suspicious activity related to the actualizador_git.php file.
• Incident Response Plan: Develop and implement an incident response plan to quickly address any exploitation attempts.
• Patch Management: Ensure a robust patch management process to apply updates promptly.
