Summary
Trudesk through 1.2.11 contains a path traversal flaw (CWE-22) in its backup handling, where file paths are not properly validated. An administrator with high privileges can remotely delete arbitrary files by supplying encoded traversal sequences to the backup delete API. Unvalidated file values in the backup restore API can also restore archives from, or extract them to, paths outside the intended directories. The references link to an exploit.
