CVE-2024-24554Network attack vector

API authentication bypass via predictable MD5 tokens

Published Jun 24, 2024 · Updated Aug 1, 2024

Improper authentication in Bludit 2.0 allows remote attackers to authenticate to its API by brute-forcing predictable tokens. The API initialization and generateAuthToken routines hash uniqid(), the current time, and the site domain with MD5, producing guessable credentials. Exploitation requires an administrator to enable the API, which is disabled by default, and grants access as an API principal.
