How the Exploit Works

The vulnerability lies in the improper limitation of a pathname to a restricted directory. This enables an attacker to traverse the directory tree to arbitrary locations within the file system. By exploiting this vulnerability, an attacker could potentially access sensitive data or execute malicious code, leading to system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how this vulnerability could potentially be exploited. In this case, an attacker sends a specially crafted request to the server, leading to a directory traversal.

GET /radio_player/../../etc/passwd HTTP/1.1
Host: target.example.com

The above request attempts to access a file (`/etc/passwd`) outside of the intended directory (`/radio_player`), demonstrating a classic path traversal attack.

Mitigation

Users of LambertGroup HTML5 Radio Player – WPBakery Page Builder Addon are advised to apply the vendor-supplied patch to mitigate this vulnerability. In the absence of a patch, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary protection against potential exploitation.
