Hewlett-Packard Data Protector DtbClsAddObject Parsing Remote Code Execution

Hewlett-Packard Data Protector DtbClsAddObject Parsing Remote Code Execution
Posted Jun 29, 2012
Authored by Aaron Portnoy, HP DVLabs | Site tippingpoint.com

A vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett-Packard Data Protector. Authentication is not required to exploit this vulnerability. The specific flaw exists within the dpwintdb.exe process which listens by default on TCP port 3817. When parsing data within a DtbClsAddObject request, the process copies data from the network into a fixed-length buffer on the stack via an unchecked loop. This can be leveraged by attackers to execute arbitrary code under the context of the SYSTEM user.
