| Doc Text: |
A flaw was found in C-Kermit. When processing certificate-based authentication in the Internet Kermit Service Daemon (IKSD) with Secure Sockets Layer (SSL) support, the service fails to reset the authentication status after a certificate login is refused. A remote attacker holding a trusted certificate mapped to a restricted account can exploit this flaw to bypass authentication and log in as any other user with an arbitrary password, resulting in unauthorized shell access to the system.
