How the Exploit Works

The vulnerability arises due to an improper limitation of a pathname to a restricted directory, commonly known as ‘Path Traversal’. An attacker, by exploiting this vulnerability, can access directories that should be restricted and read, modify, or delete files that are outside the intended directory. This can lead to unauthorized disclosure of information, unauthorized modification, or unauthorized disruption of service.

Conceptual Example Code

A conceptual example of the exploit may look like the following HTTP request:

GET /filelist/?dir=../../../../etc/passwd HTTP/1.1
Host: target.example.com

In this example, the attacker uses a series of “../” to move up in the directory structure to access the /etc/passwd file, a sensitive file that contains user password hashes on Unix-like systems.

Mitigation Guidance

In order to mitigate this vulnerability, users are advised to update Mitchell Bennis Simple File List to the latest version where this vulnerability has been patched. If an immediate update is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block path traversal attacks can serve as a temporary mitigation measure. However, these temporary measures do not fully eliminate the vulnerability and are not a substitute for applying the vendor-supplied patch.
