DESCRIPTION:
DarkFig has reported some vulnerabilities in CS-Forum, which can be
exploited by malicious people to conduct cross-site scripting and SQL
injection attacks, and use it as an open mail relay.

1) Input passed to the "msg_result" and "rep_titre" parameters in
read.php, the "id" and "parent" parameters in ajouter.php, and the
"CSForum_nom", "CSForum_mail", and "CSForum_url" cookie parameters
isn't properly sanitised before being returned to the user. This can
be exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

2) Input passed to the "id" and "debut" parameters in read.php, and
the "search" and "debut" parameters in index.php isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "email" parameter in ajouter.php isn't
properly sanitised before being used in a "mail()" call. This can be
exploited to inject arbitrary mail headers via the newline
character.

It is also possible to disclose the full path to index.php by
defining certain parameters.

The vulnerabilities have been reported in version 0.81. Prior
versions may also be affected.

SOLUTION:
Update to version 0.82.
