QID 730072

Date Published: 2021-05-12

QID 730072: Matt Wright's guestbook.pl Present on Apache

The script 'guestbook.pl' by Matt Wright was detected on your server. Some versions of this script processes user-inserted SSI commands by removing text between "" separators. This allows remote attackers to execute arbitrary commands when guestbook.pl is run on Apache 1.3.9 (and possibly other versions) since Apache allows other closing sequences besides "-->".

A vulnerable version of guestbook.pl could allow a remote user to execute arbitrary commands.

CVSS V3 rated as Critical - 9.8 severity.

CVSS V2 rated as High - 7.5 severity.

Solution

Make sure the guestbook.pl script on the host is not vulnerable. If it is, a temporary solution is to disable server side includes in Apache. The latest version of the script can be found at GuestBook.
