A vulnerability has been identified in Cahier de texte, which could be exploited by attackers to gain unauthorized access to arbitrary files on a vulnerable system. This flaw is due to input validation errors in the "administration/telecharger.php" script that does not validate the "Fichier_a_telecharger" and "chemin" (version 2.0) parameters before being passed to a "readfile()" call, which could be exploited by malicious users to access and read the contents of arbitrary files.
Note : A database backup (dump.sql) is stored in the "administration" directory and is accessible without protection.
