The server in IBM Tivoli Storage Manager (TSM) 5.x and 6.x before 6.3.5.10 and 7.x before 7.1.1.100 allows remote attackers to bypass intended access restrictions and replace file backups by using a certain backup option in conjunction with a filename that matches a previously used filename.
The server in IBM Tivoli Storage Manager (TSM) 5.1.x, 5.2.x before 5.2.1.2, and 6.x before 6.1 does not require credentials to observe the server console in some circumstances, which allows remote authenticated administrators to monitor server operations by establishing a console mode session, related to "session exposure."
