"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."
