IBM TSM FastBack Mount Service Arbitrary Overwrite Remote Code Execution Vulnerability

Reference ID: SSA-1009
Publication date: 29.09.2010
Severity: critical

Affected versions: 5.5.0.0 - 5.5.6.0 and 6.1.0.0 - 6.1.0.1

Description from ZDI advisory: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM Tivoli Storage Manager Fastback. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Mount service (FastBackMount.exe). This process listens by default on UDP port 30005. This process writes the value 0x01 to the address specified by the second DWORD from a packet received to it’s UDP port. An attacker can exploit this behavior to execute arbitrary code by making several requests to this service.
