This vulnerability allows an attacker to execute remote code on vulnerable installations of the Hewlett-Packard Data Protector client. User interaction is not required to exploit this vulnerability. The specific flaw exists within the implementation of the EXEC_SETUP command. This command instructs a Data Protector client to download and execute a setup file. A malicious attacker can instruct the client to access a file off of a share thus executing arbitrary code under the context of the current user.
