What is CVE-2017-9833?

A vulnerability in the Boa Web Server version 0.94.14rc21 allows attackers to exploit the /cgi-bin/wapopen endpoint. By manipulating the FILECAMERA variable through a GET request, unauthorized users can inject a path traversal sequence ('../..'), which could potentially expose system files with root privileges. This vulnerability has been noted as a system integrator issue, primarily affecting specific camera models that utilize the Boa web server without full implementations of security checks or the necessary code to handle such requests properly.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
