How the Exploit Works
The exploit takes advantage of an improper limitation of a pathname to a restricted directory (‘Path Traversal’) vulnerability in the Apptha Slider Gallery. An attacker can manipulate variables that reference files with ‘dot-dot-slash (../)’ sequences and its variations such as ‘http://’, thereby navigating out of the intended directory and gaining access to unauthorized files or directories.
Conceptual Example Code
Below is a simplified conceptual example of a malicious HTTP request exploiting the Path Traversal vulnerability:
GET /loadImage?filename=../../etc/passwd HTTP/1.1
Host: target.example.comIn this example, instead of loading an image, the attacker is attempting to retrieve a sensitive file (‘/etc/passwd’) from the server.
Mitigation
Until a patch is available from the vendor, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure. These systems can detect and block attempts to exploit this vulnerability by inspecting incoming HTTP requests for patterns indicative of Path Traversal attacks.
