CyberRota Analysis

AI-Generated

osTicket 1.18.3 is vulnerable due to its use of predictable API key generation based on MD5 hashing, which relies on easily guessable inputs like the current timestamp and client IP address. This flaw allows attackers to brute-force API keys, potentially compromising the security of the application. Organizations using this version of osTicket should prioritize immediate remediation to protect against unauthorized access.

Original NVD Description

osTicket 1.18.3 generates API keys using a predictable construction based on MD5 hashing. The use of MD5, combined with predictable inputs such as the current timestamp and client IP address, significantly reduces entropy. An attacker can approximate the key generation time and brute-force the key space within a feasible time window.
