How the Exploit Works
The vulnerability involves a Path Traversal issue that allows PHP Local File Inclusion. This means that an attacker can manipulate variables that reference files with a ‘dot-dot-slash’ (../) sequence, causing the software to access files or directories that are outside the restricted directory. This issue is particularly dangerous due to the ability to include PHP files from any location, which can lead to remote code execution and potential system compromise.
Conceptual Example Code
To exploit this vulnerability, an attacker may send a malicious HTTP request similar to the following:
GET /path-to-vulnerable-endpoint/?file=../../etc/passwd HTTP/1.1
Host: vulnerable-website.comIn this example, the attacker manipulates the ‘file’ parameter to traverse up the directory tree and include the /etc/passwd file. This file contains sensitive information that forms the basis for user identity verification on UNIX-like operating systems.
Mitigation Guidance
Given the potential for system compromise or data leakage, it is recommended that users of Frenify Arlo update their software to the latest version where this vulnerability has been patched. If updating is not immediately possible, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure to mitigate this vulnerability.
