CVE-2021-25783Public exploitNetwork attack vector

Authenticated database compromise via Article Search injection

Published Dec 2, 2021 · Updated Aug 3, 2024

Blind SQL injection in TaoCMS 2.5 Beta5 allows remote authenticated users to access database data through Article Search. The administrative article-list endpoint accepts SQL syntax in the name parameter, allowing a Boolean condition to alter the database query. Administrator access to the CMS backend is required; successful exploitation provides a blind oracle for reading or changing database contents.
