CVE-2025-32352 Details
Description
A type confusion vulnerability in lib/NSSAuthenticator.php in ZendTo before v5.04-7 allows remote attackers to bypass authentication for users with passwords stored as MD5 hashes that can be interpreted as numbers. A solution requires moving from MD5 to bcrypt.
A type confusion vulnerability has been identified in ZendTo versions prior to 5.04-7, specifically within the NSSAuthenticator component. This vulnerability allows remote attackers to bypass authentication for users whose passwords are stored as MD5 hashes that can be interpreted as numerical values. The issue arises because the authentication process improperly compares hashed passwords, enabling exploitation through crafted input. Additionally, for ZendTo versions greater than 5.03-1, the authentication bypass still affects users with legacy MD5 hashes.
Upgrade to ZendTo version 5.04-7 or later and have all users log in at least once to transition their passwords to bcrypt.
