Does this matter?

Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.

Description

Windu CMS uses hashing algorithm based on MD5 and SHA1 with static salt to store user passwords. This allows an attacker who obtain password hash to decode user credentials. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 4.1 but may also affect other versions.
