CVE-2024-23790Network attack vector

Data disclosure via unchecked avatar file types

Published Jan 29, 2024 · Updated Jun 17, 2025

Improper input validation in affected OTRS releases allows remote authenticated users to disclose data through crafted avatar uploads. The Agent Interface and External Interface avatar upload handlers accept files without checking their types against the permitted image-type list. A low-privileged account and another user's interaction are required; OTRS reports limited confidentiality impact but has not disclosed which data becomes exposed.
