Technical Description

Multiple vulnerabilities have been identified in CS-Forum, which could be exploited by remote attackers to bypass security restrictions or perform SQL injection and cross site scripting.

The first issue is due to input validation errors in the "read.php" and "ajouter.php" scripts that do not validate certain parameters, which could be exploited by attackers to cause malicious scripting code to be executed by the user's browser.

The second flaw is due to input validation errors in the "read.php" and "index.php" scripts that do not validate the "id", "debut", and "search" parameters, which could be exploited by malicious people to conduct SQL injection attacks.

The third vulnerability is due to an input validation error in the "ajouter.php" script that does not validate the "email" parameter, which could be exploited by remote attackers to inject arbitrary email headers.

Note : An error in the "index.php" script when handling invalid parameters could be exploited by attackers to determine the installation path.
