Title
Weak password hashing in R-SOFT DMS
Summary
R-SOFT DMS stores superadmin credentials using a non-salted nested MD5 hash. This allows an attacker who obtain password hash to decode superadmin credentials. Critically, this password cannot be changed except by modifying the configuration file. This issue was fixed in version v3.17-2000.
