CVE-2024-23792Network attack vector

Ticket attachment impersonation via reused comment UUID

Published Jan 29, 2024 · Updated Nov 12, 2024

Improper authentication in OTRS allows remote authenticated users to add files to another user's pending ticket comment via the internal API. The attachment operation accepts a comment UUID from a different authenticated session and associates the supplied file with the original user's unfinished comment. Exploitation requires knowledge of that UUID during the comment-completion window and results in unauthorized files being attributed to the legitimate user.
