What is CVE-2018-6328?

An issue was identified in Unitrends Backup prior to version 10.1.0 where the user interface was susceptible to an authentication bypass. This vulnerability allows unauthorized users to exploit the system by injecting arbitrary commands into the /api/hosts parameters using backquotes. This could lead to significant security risks if not addressed, as it permits access to sensitive functions without proper authentication.

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.
