Detailsinfo

A vulnerability classified as problematic was found in Suprema BioStar 2 2.9.8/2.9.10/2.9.11. This vulnerability affects an unknown code of the file /api/migration. The manipulation with an unknown input leads to a uncaught exception vulnerability. The CWE definition for the vulnerability is CWE-248. An exception is thrown from a function, but it is not caught. As an impact it is known to affect availability. CVE summarizes:

An unhandled exception in Suprema BioStar 2 (Server), versions 2.9.8, 2.9.10, and 2.9.11, that allows an unauthenticated remote attacker to cause a denial of service (DoS) by sending HTTP POST requests to the ‘/api/migration’ endpoint. This request triggers a failure that halts critical processes, leaving the system offline until the services or server are manually restarted. As a result, access control readers cease to function, and potential failures may occur in third-party integrations. Since the exploit requires no privileges or user interaction and is trivial to automate, the impact on availability is high, and the effect extends to interconnected systems.

The weakness was published by Jordi Garcia Ribera. The advisory is available at incibe.es. This vulnerability was named CVE-2026-9509 since 05/25/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.
