Name of the Vulnerable Software and Affected Versions osTicket version 1.18.3
Description The software generates API keys using a predictable construction based on MD5 hashing. The combination of MD5 with predictable inputs, specifically the current timestamp and client IP address, significantly reduces entropy. This allows an attacker to approximate the key generation time and brute-force the key space within a feasible time window.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
