Two vulnerabilities have been identified in phpBazar, which could be exploited by remote attackers to execute arbitrary commands or bypass security restrictions.

The first issue is due to an error in the "admin/admin.php" script, which could be exploited by remote attackers to bypass the authentication process and gain unauthorized access to the administrative section by setting the "action" parameter to "edit_member" and the "value" parameter to "1".

The second flaw is due to an input validation error in the "classified_right.php" script that does not validate the "language_dir" parameter, which could be exploited by remote attackers to include malicious scripts and execute arbitrary commands with the privileges of the web server.
