guestbook.pl contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is triggered when the Guestbook option is enabled that allows HTML posting and the Web server has SSI (Server-Side Include) enabled for .html files. It is possible that the flaw may allow a remote attacker to insert SSI code in guestbook messages and execute arbitrary commands with the privileges of the Web server resulting in a loss of integrity.
