According to its self-reported version, the Tivoli Endpoint installation running on the remote host is earlier than 4.1.1-LCF-0076 or 4.3.1-LCF-0012LA, and therefore has a buffer overflow vulnerability. Input to the ‘opts’ parameter of ‘/addr’ is not properly validated. Authentication is required for exploitation, though this can be achieved trivially by using a built-in account.
A remote, authenticated attacker could exploit this by sending a malicious POST request to the server, resulting in arbitrary code execution.
