What is CVE-2024-49358?

CVE-2024-49358 is a medium-severity vulnerability in IceWhaleTech ZimaOS, published on 24 Oct 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.2.4 and all prior versions, the API endpoint `http://<Server-IP>/v1/users/login` in ZimaOS returns distinct responses based on whether a username exists or the password is incorrect. This behavior can be exploited for username enumeration, allowing attackers to determine whether a user exists in the system or not. Attackers can leverage this information in further attacks, such as credential stuffing or targeted password brute-forcing. As of time of publication, no known patched versions are available.

Weakness: CWE-203
