User enumeration vulnerability in M3M Printer Server Web.

MEDIUM 6.9EPSS 0.40%

Does this matter?

Lower severity and a low EPSS score (0.40%). Track it; it rarely justifies an emergency change on its own.

Description

User enumeration vulnerability in M3M Printer Server Web. This issue occurs during user authentication, where a difference in error messages could allow an attacker to determine whether a username is valid or not, allowing a brute force attack on valid usernames.
