CVE-2025-26615

Remediation/Mitigation Strategy for CVE-2025-26615 - WeGIA Path Traversal

This document outlines the vulnerability, severity, known exploit, and the remediation/mitigation strategy for CVE-2025-26615, a Path Traversal vulnerability in the WeGIA web application.

1. Vulnerability Description

  • Vulnerability: Path Traversal
  • Affected Component: examples.php endpoint
  • Description: A Path Traversal vulnerability exists in the examples.php endpoint of the WeGIA web application. This vulnerability allows an attacker to access files outside of the intended directory. Specifically, it can be exploited to read the config.php file, which contains sensitive database connection information.

2. Severity Assessment

  • CVE: CVE-2025-26615
  • CVSS Score: 6.0 (Medium) based on provided information
  • CVSS Vector: (Inferred based on provided information) likely AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N (Network, Low Attack Complexity, No Privileges Required, No User Interaction, Unchanged Scope, High Confidentiality Impact, No Integrity Impact, No Availability Impact)
  • Severity Level: Medium
  • Justification: Although the attacker can only read the config.php file (no integrity or availability impact), the compromise of database credentials represents a significant security risk. A compromised database can lead to further data breaches, service disruption, and potential reputational damage. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk.

3. Known Exploits

  • Exploitability: Exploitable over the network without authentication.
  • Exploit Details: An attacker can craft a malicious URL that includes path traversal sequences (e.g., ../, ../../) to navigate to the config.php file and retrieve its contents. Example: http://<wegia_server>/examples.php?file=../../config.php
  • Known Workarounds: None identified by the advisory.

4. Remediation Strategy

The primary remediation strategy is to upgrade to the patched version of WeGIA (version 3.2.14 or later). If immediate upgrade is not possible, mitigation steps should be implemented to minimize risk.

  • Immediate Action: Upgrade

    • Action: Upgrade to WeGIA version 3.2.14 or later immediately.
    • Procedure: Follow the official WeGIA upgrade instructions. Back up the existing installation and database before starting the upgrade. Thoroughly test the upgraded system in a staging environment before deploying it to production.
    • Timeline: Immediately. This is the highest priority.

  • Short-Term Mitigation (If Upgrade is Delayed)

    If an immediate upgrade is not feasible, implement the following mitigation steps as soon as possible:

    • Access Control Restriction:

      • Action: Restrict access to the examples.php file.
      • Procedure: Configure the web server (e.g., Apache, Nginx) to deny access to the examples.php file from outside the local network or trusted sources. Use IP address restrictions or authentication requirements.
      • Example (Apache): <Location /examples.php> Require ip 127.0.0.1 # Or, require a valid user: # Require valid-user * Example (Nginx): location = /examples.php { allow 127.0.0.1; deny all; } * Timeline: Within 24 hours.

    • Web Application Firewall (WAF) Rule:

      • Action: Implement a WAF rule to detect and block path traversal attempts targeting examples.php.
      • Procedure: Configure a WAF (if available) with a rule to block requests containing path traversal sequences (e.g., ../, ../../) in the file parameter of the examples.php URL.
      • Timeline: Within 48 hours.

    • Log Monitoring:

      • Action: Enhance logging and monitoring for access to examples.php and for any path traversal attempts.
      • Procedure: Configure the web server to log all requests to examples.php. Implement intrusion detection systems (IDS) or security information and event management (SIEM) tools to analyze logs for suspicious activity, such as path traversal attempts.
      • Timeline: Within 72 hours.

  • Long-Term Strategy

    • Secure Coding Practices:

      • Action: Implement and enforce secure coding practices to prevent path traversal and other vulnerabilities in future development.
      • Procedure: Train developers on secure coding principles, including input validation and output encoding. Implement code reviews to identify and address potential vulnerabilities. Use static analysis tools to automatically detect vulnerabilities in the code.
      • Timeline: Ongoing.

    • Regular Security Audits:

      • Action: Conduct regular security audits and penetration testing to identify and address vulnerabilities in the WeGIA application and its environment.
      • Procedure: Engage qualified security professionals to perform vulnerability assessments and penetration tests. Address any vulnerabilities identified during these assessments in a timely manner.
      • Timeline: At least annually, or more frequently if significant changes are made to the application.

    • Vulnerability Scanning:

      • Action: Implement automated vulnerability scanning tools to regularly scan the WeGIA application for known vulnerabilities.
      • Procedure: Use vulnerability scanning tools to scan the application for known vulnerabilities. Configure the tools to automatically report any vulnerabilities identified. Address any vulnerabilities identified during these scans in a timely manner.
      • Timeline: At least weekly, or more frequently if possible.

5. Verification

After applying the remediation steps, verify their effectiveness:

  • Upgrade Verification: After upgrading, verify that the examples.php endpoint is no longer vulnerable to path traversal. Attempt the known exploit URL (e.g., http://<wegia_server>/examples.php?file=../../config.php) and confirm that it returns an error or is blocked.
  • Mitigation Verification: If applying mitigations instead of upgrading, verify that the access control restrictions, WAF rules, and logging are functioning correctly.

6. Communication

  • Communicate the vulnerability and the remediation plan to all relevant stakeholders, including IT staff, developers, and management.
  • Provide regular updates on the progress of the remediation efforts.

This remediation strategy should be reviewed and updated as needed to reflect changes in the threat landscape and the WeGIA application. Prioritize the upgrade to version 3.2.14 or later as the most effective solution.
