The server in IBM Spectrum Protect (aka Tivoli Storage Manager) 5.5 and 6.x before 6.3.5.1 and 7.x before 7.1.4 does not properly restrict use of the ASNODENAME option, which allows remote attackers to read or write to backup data by leveraging proxy authority.
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.
