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 Backup-Archive client in IBM Tivoli Storage Manager (TSM) for Space Management 5.x and 6.x before 6.2.5.3, 6.3.x before 6.3.2, 6.4.x before 6.4.2, and 7.1.x before 7.1.0.3 on Linux and AIX, and 5.x and 6.x before 6.1.5.6 on Solaris and HP-UX, does not preserve file permissions across backup and restore operations, which allows local users to bypass intended access restrictions via standard filesystem operations.
