Technical Description

Multiple vulnerabilities were identified in SPIP, which could be exploited by malicious people to perform SQL injection and cross site scripting attacks.

The first issue is due to an input validation error in "index.php3" when processing a specially crafted "lang" variable, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser.

The second flaw is due to input validation errors in the "forum.php3" script that fails to properly validate the "id_article" and "id_forum" variables, which may be exploited by malicious people to conduct SQL injection attacks.

The third vulnerability is due to an error in the "inc-messforum.php3" script when accessed directly via the browser, which could be exploited by remote attackers to determine the installation path.
