Vulnerability Note VU#441363

HP Virtual SAN appliance root shell command injection

Original Release date: 17 Aug 2012 | Last revised: 17 Aug 2012


The HP Virtual SAN appliance version 9.5 is susceptible to a root shell command injection (CWE-77) vulnerability.


Tenable Network Security has reported that HP's fix for the command injection vulnerability, EDB-ID 18893, was incomplete. The ping command for the appliance has a total of four parameters. The initial fix has only sanitized the input for one of the four parameters. Command injection is still possible against the other three parameters.


An authenticated attacker can run arbitrary commands on the appliance.


We are currently unaware of a practical solution to this problem. Please consider the following workarounds.

Restrict access

As a general good security practice, only allow connections from trusted hosts and networks. Restricting access would prevent an attacker from accessing an HP Virtual SAN appliance using stolen credentials from a blocked network location.
