CVE-2021-3833
An attacker with a specific formatted password could exploit this vulnerability in order to login in the system with different passwords.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.12%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Integria IMS login check uses a loose comparator ("==") to compare the MD5 hash of the password provided by the user and the MD5 hash stored in the database. An attacker with a specific formatted password could exploit this vulnerability in order to login in the system with different passwords.
