'Name' => 'Oracle VM Server Virtual Server Agent Command Injection',

|
||||
This module exploits a command injection flaw within Oracle\'s VM Server
|
||||
Virtual Server Agent (ovs-agent) service.
|
||||
|
||||
By including shell meta characters within the second parameter to the 'urt_test_url'
|
||||
XML-RPC methodCall, an attacker can execute arbitrary commands. The service
|
||||
typically runs with root privileges.
|
||||
|
||||
NOTE: Valid credentials are required to trigger this vulnerable. The username
|
||||
appears to be hardcoded as 'oracle', but the password is set by the administrator
|
||||
at installation time.
