MEDIUM 5.3EPSS 1.85%

Does this matter?

Lower severity and a low EPSS score (1.85%). Track it; it rarely justifies an emergency change on its own.

Description

An issue was discovered in /goform/login_process in Reprise RLM 14.2. When an attacker attempts to login, the response if a username is valid includes Login Failed, but does not include this string if the username is invalid. This allows an attacker to enumerate valid users.
