Remediation/Mitigation Strategy: CVE-2025-32146 - PHP Local File Inclusion in JS Job Manager

This document outlines the remediation and mitigation strategies for CVE-2025-32146, a PHP Local File Inclusion (LFI) vulnerability discovered in JS Job Manager versions up to and including 2.0.2.

1. Vulnerability Description:

  • Vulnerability: PHP Local File Inclusion (LFI)
  • CWE: CWE-98 - Improper Control of Filename for Include/Require Statement in PHP Program (‘PHP Remote File Inclusion’) - Although labeled ‘PHP Remote File Inclusion’ in the report, the actual vulnerability is LFI.
  • Affected Software: JS Job Manager
  • Affected Versions: Versions up to and including 2.0.2

2. Severity Assessment:

  • CVSS Score: 8.8 (High)
    • CVSS Vector: (Based on report data) CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H (Inferred)
  • Severity: High
  • Impact: An attacker can include and execute arbitrary PHP files on the server, potentially leading to:
    • Code Execution: Execution of malicious PHP code on the server.
    • Data Exposure: Access to sensitive data stored on the server (e.g., database credentials, configuration files).
    • Server Compromise: Complete compromise of the web server.
  • Attack Vector: Network

3. Known Exploitability:

  • Exploit Exists: The existence of CVE-2025-32146 itself indicates a discovered exploit. While specific exploit details are not included in the provided report, LFI vulnerabilities are generally well-understood and easily exploitable. The provided data indicates the vulnerability is easy to exploit (Attack Complexity: Low).

4. Remediation Strategy:

  • Immediate Action (Highest Priority):
    • Upgrade JS Job Manager: Upgrade to a patched version of JS Job Manager that addresses CVE-2025-32146. Consult the JS Job Manager vendor’s website for the latest version and security patches. If a patch isn’t readily available, move to Mitigation Strategy.

5. Mitigation Strategy (If a patch is unavailable or upgrade is delayed):

  • Input Validation: Implement strict input validation on all parameters that are used to specify file paths within the JS Job Manager code. This should include:
    • Whitelisting: Only allow known, safe file names or extensions. Reject any input that doesn’t match the whitelist. This is the most effective approach.
    • Path Sanitization: Remove or encode characters that could be used for directory traversal (e.g., “..”, “/”, “"). Ensure paths are normalized to prevent bypasses.
    • Input Length Limitation: Limit the length of the input parameter to prevent overly long file paths.
  • Directory Restrictions: Restrict the files that can be included or required to a specific directory. This can be achieved through configuration settings or by modifying the code to only allow files within a designated safe directory. Use realpath() to ensure that the final file path remains within the allowed directory.
  • Disable allow_url_include: In the php.ini file, ensure that the allow_url_include setting is disabled (allow_url_include = Off). This prevents the inclusion of remote files, reducing the attack surface. Note: This won’t prevent LFI but will prevent Remote File Inclusion (RFI).
  • Web Application Firewall (WAF): Deploy a WAF and configure it with rules to detect and block LFI attacks. Update the WAF rules regularly to stay ahead of new attack techniques. Look for patterns like directory traversal attempts (”../") in request parameters.
  • Least Privilege Principle: Run the web server process with the least privileges necessary. This limits the potential damage an attacker can cause if they successfully exploit the vulnerability.
  • Regular Security Audits: Conduct regular security audits of the JS Job Manager code to identify and address potential vulnerabilities. Use automated scanning tools and manual code reviews.
  • Monitor Logs: Enable comprehensive logging and monitoring to detect suspicious activity. Monitor for unusual file access patterns, failed login attempts, and other indicators of compromise.
  • Disable Unnecessary Features: Disable any JS Job Manager features that are not essential for the application’s functionality. This reduces the attack surface.
  • File System Permissions: Review and harden file system permissions. Ensure that the web server user only has the necessary permissions to access and modify files. Prevent the webserver user from being able to write to the upload directory.

6. Testing and Validation:

  • After implementing the remediation or mitigation strategies, thoroughly test the application to ensure that the vulnerability has been addressed and that the application is functioning correctly.
  • Use penetration testing techniques to simulate real-world attacks and verify the effectiveness of the security measures.

7. Communication:

  • Communicate the vulnerability and the remediation/mitigation plan to all stakeholders, including developers, system administrators, and users.
  • Keep stakeholders informed of the progress of the remediation efforts.

8. Long-Term Security:

  • Adopt a secure development lifecycle (SDLC) to prevent future vulnerabilities.
  • Provide security training to developers to educate them about common vulnerabilities and secure coding practices.

Important Considerations:

  • Always back up your system before applying any patches or making configuration changes.
  • Test changes in a non-production environment before deploying them to production.
  • Consult the JS Job Manager vendor’s documentation for the latest security recommendations.

This strategy is based on the limited information provided. A more complete assessment of the application code would allow for a more tailored and effective remediation plan.
