Vulnerability Details

This 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.

Hewlett-Packard has issued an update to correct this vulnerability. More details can be found at:
