How the Exploit Works
This vulnerability exists due to the improper limitation of a pathname to a restricted directory (‘Path Traversal’) in the mentioned software. It allows an attacker to read, write, or execute files outside of the application’s restricted directory, which could lead to unauthorized access to sensitive data or a potential system compromise.
Conceptual Example Code
The conceptual example below showcases how an attacker could potentially exploit this vulnerability. The attacker sends a request with a manipulated “file” parameter that includes path traversal characters (../):
GET /vulnerable/endpoint?file=../../../../etc/passwd HTTP/1.1
Host: target.example.com
Mitigation
Users of the impacted UPC/EAN/GTIN Code Generator software are advised to apply the latest patch provided by the vendor to rectify this vulnerability. As a temporary mitigation measure, users can deploy a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and prevent any potential exploit attempts.
