Version Summary:Functional code that demonstrates an exploit of the HP Data Protector OmniInet service remote command execution vulnerability is publicly available.
 
 
Description
A vulnerability in the Backup Client Service (omniinet.exe) of HP Data Protector could allow an unauthenticated, remote attacker to execute arbitrary commands.

The vulnerability is due to insufficient validation of user-supplied input processed by the affected software while handling certain messages. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted EXEC_BAR packet to an affected device. If successful, the attacker could execute arbitrary commands in the security context of the SYSTEM user, which could result in a complete system compromise.

Functional code that exploits this vulnerability is available as part of the Metasploit framework.

HP has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
HP Data Protector versions prior to 6.21 are affected.
 
IntelliShield Analysis
To exploit this vulnerability, it is likely that an attacker would need access to trusted, internal networks to send crafted EXEC_BAR packets to an affected device. This access requirement limits the likelihood of a successful exploit.
