CVE-2022-47002Public exploitNetwork attack vector

Unauthenticated account takeover via empty hash acceptance

Published Feb 1, 2023 · Updated Aug 3, 2024

Authentication bypass in Masa CMS 7.2, 7.3, and 7.4-beta allows remote attackers to log in as any site member or system user. The rememberMe function in core/mura/login/loginManager.cfc accepts a zero-length decrypted userHash because an OR condition treats an empty hash as valid. A crafted request requires a valid user ID, obtainable through the unauthenticated JSON API, and then grants that account's application access.
