dirsys/modules/auth.php in JBC Explorer 7.20 RC1 and earlier does not require authentication, which allows remote attackers to (1) delete auth.inc.php via the suppr parameter, and (2) re-create the auth.inc.php file with contents that specify a new account name and password for JBC Explorer via the login and password parameters.

Direct static code injection vulnerability in dirsys/modules/config/post.php in JBC Explorer 7.20 RC1 and earlier allows remote authenticated administrators to inject arbitrary PHP code via the DEBUG parameter, which can be executed by accessing config.inc.php. NOTE: this can be exploited by unauthenticated remote attackers by leveraging CVE-2007-5913.
