CVE-2024-54291
Remediation/Mitigation Strategy for CVE-2024-54291
Vulnerability: Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’)
Description: The NotFound PluginPass plugin, versions 0.9.10 and earlier, is vulnerable to a path traversal attack. This vulnerability allows attackers to manipulate web input, causing the application to access or modify files outside of the intended restricted directory.
Severity: High (CVSS Score: 8.6)
Known Exploit: Attackers can leverage this vulnerability by crafting malicious requests containing directory traversal sequences (e.g., ../) in the URL or request parameters. This can lead to unauthorized file access, information disclosure, or even arbitrary code execution depending on the specific server configuration and permissions. Specific exploit details are not provided, but the general nature of path traversal vulnerabilities is well-understood and readily exploitable with standard web penetration testing tools.
Remediation:
- Upgrade: Upgrade the NotFound PluginPass plugin to a version beyond 0.9.10 or apply the patch provided by the vendor if one is available. This is the most effective solution.
Mitigation:
If upgrading is not immediately possible, consider the following mitigations:
Input Validation: Implement strict input validation on all user-supplied input that is used to construct file paths. Sanitize input by removing or encoding potentially dangerous characters and sequences, such as
../,..\\,%2e%2e%2f, and%2e%2e%5c.Path Canonicalization: Use path canonicalization functions (e.g.,
realpath()or equivalent in your programming language) to resolve symbolic links and ensure that the resulting path remains within the intended restricted directory.Least Privilege Principle: Ensure that the web server and application processes run with the least necessary privileges. Restrict the file system permissions of the user account under which the application runs to limit the impact of a successful path traversal attack.
Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) and configure it with rules to detect and block path traversal attempts. Ensure the WAF is regularly updated with the latest vulnerability signatures.
Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the application and its dependencies.
Monitoring:
- Monitor web server logs for suspicious activity, such as requests containing path traversal sequences.
- Implement intrusion detection systems (IDS) to detect and alert on potential exploitation attempts.
