How the Exploit Works
The exploit works by the attacker sending specially crafted input to the WHMpress application. This input, which involves a relative path, is not properly sanitized by the software, allowing the attacker to traverse directories outside of the intended boundary. This could potentially give the attacker access to sensitive system files and data.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited, using an HTTP request:
GET /WHMpresspage?file=../../etc/passwd HTTP/1.1
Host: target.example.comIn this example, the attacker is attempting to access a sensitive system file (the Unix password file) via relative path traversal by moving up two directory levels from the expected context.
Mitigation
To mitigate this high-risk Path Traversal vulnerability, users are strongly recommended to apply the vendor’s patches as soon as they become available. In the interim, utilizing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and potentially blocking attempts to exploit this vulnerability. Regularly review and update security protocols to ensure the best possible defense against potential threats.
