ZKTeco BioTime

ZKTeco BioTime 8.5.5 through 9.x before 9.0.1 (20240617.19506) allows authenticated attackers to create or overwrite arbitrary files on the server via crafted requests to /base/sftpsetting/ endpoints that abuse a path traversal issue in the Username field and a lack of input sanitization on the SSH Key field. Overwriting specific files may lead to arbitrary code execution as NT AUTHORITY\SYSTEM.

A path traversal vulnerability in the iclock API of ZKTeco BioTime v8.5.5 allows unauthenticated attackers to read arbitrary files via supplying a crafted payload. This vulnerability was fixed in version 9.0.120240617.19506 of ZKBioTime.

Insecure access control in ZKTeco BioTime through 9.0.1 allows authenticated attackers to escalate their privileges due to the fact that session ids are not validated for the type of user accessing the application by default. Privilege restrictions between non-admin and admin users are not enforced and any authenticated user can leverage admin functions without restriction by making direct requests to administrative endpoints.

An issue in a hidden API in ZKTeco BioTime v8.5.5 allows unauthenticated attackers to arbitrarily reset the Administrator password via a crafted web request.
