What is CVE-2018-20166?

A file-upload vulnerability exists in Rukovoditel 2.3.1, specifically in the configuration module. This flaw allows users to upload background images but fails to properly validate file extensions. It permits PHP file uploads disguised as GIF files, as long as they start with the correct header but possess a mixed case extension such as '.pHp'. This misconfiguration can lead to unauthorized code execution on the server, thereby compromising the integrity of the application.

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.
