IBM Spectrum Protect, formerly known as Tivoli Storage Manager, running on the remote host is version 7.1.x < 7.1.10.100 or 8.1.x < 8.1.9.300. It is, therefore, is vulnerable to a stack-based buffer overflow which could allow an unauthenticated, remote attacker to executive arbitrary code on the system or cause the IBM Spectrum Protect Server to crash.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
