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.
