CVE-2025-13597

Comprehensive Technical Analysis of CVE-2025-13597

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-13597 CVSS Score: 9.8

The vulnerability in the AI Feeds plugin for WordPress allows for arbitrary file uploads due to a missing capability check in the actualizador_git.php file. This flaw enables unauthenticated attackers to download arbitrary GitHub repositories and overwrite plugin files on the affected site's server, potentially leading to remote code execution (RCE).

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates a critical vulnerability that poses a significant risk to affected systems. The ability for unauthenticated attackers to execute arbitrary code on the server makes this vulnerability particularly dangerous.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

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

Exploitation Methods:

1. Direct Exploitation: Attackers can directly target the actualizador_git.php file to upload malicious files.
2. Phishing and Social Engineering: Attackers may use phishing techniques to lure users into visiting malicious sites that exploit the vulnerability.
3. Automated Scanning: Attackers can use automated tools to scan for vulnerable WordPress installations and exploit the vulnerability en masse.

3. Affected Systems and Software Versions

Affected Software:

• AI Feeds plugin for WordPress
• Versions up to and including 1.0.11

Affected Systems:

• Any WordPress installation using the AI Feeds plugin versions up to 1.0.11.
• Servers hosting these WordPress installations.

4. Recommended Mitigation Strategies

1. Immediate Patching:

   • Update the AI Feeds plugin to a version that includes the fix for this vulnerability.
   • Ensure all WordPress plugins and core files are up to date.

2. Access Controls:

   • Implement strict access controls to limit who can upload files to the server.
   • Use role-based access control (RBAC) to restrict administrative privileges.

3. Monitoring and Logging:

   • Enable comprehensive logging to monitor for suspicious activities.
   • Use security plugins like Wordfence to detect and block malicious uploads.

4. Web Application Firewalls (WAF):

   • Deploy a WAF to filter out malicious requests and protect against known vulnerabilities.

5. Regular Security Audits:

   • Conduct regular security audits and vulnerability assessments to identify and mitigate potential risks.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-13597 highlights the ongoing challenge of securing third-party plugins and extensions, which are often the weakest link in web application security. This vulnerability underscores the importance of:

• Regular Updates: Ensuring all plugins and software are kept up to date.
• Vendor Accountability: Holding plugin developers accountable for secure coding practices.
• User Awareness: Educating users on the risks associated with third-party plugins and the importance of security best practices.

6. Technical Details for Security Professionals

Vulnerable File: actualizador_git.php Vulnerability Type: Arbitrary File Upload Root Cause: Missing capability check

Exploitation Steps:

1. Identify Target: Locate a WordPress site using the vulnerable version of the AI Feeds plugin.
2. Craft Malicious Payload: Create a malicious GitHub repository or file designed to overwrite existing plugin files.
3. Upload Payload: Use the vulnerability to upload the malicious file to the server.
4. Execute Code: Trigger the uploaded file to execute arbitrary code on the server.

Detection and Response:

• Indicators of Compromise (IoCs): Monitor for unusual file uploads and modifications to plugin files.
• Incident Response: Immediately isolate affected systems, apply patches, and conduct a thorough investigation to identify the extent of the compromise.
