Multiple SQL injection vulnerabilities in changePW.php in AV Tutorial Script (avtutorial) 1.0, when magic_quotes_gpc is disabled, allow remote attackers to execute arbitrary SQL commands via the (1) id and (2) userid parameters, a different issue than CVE-2007-3630.

admin/index.php in AV Arcade 2.1b grants administrative privileges when the ava_userid cookie value is 1, which allows remote attackers to perform certain administrative actions.

changePW.php in AV Tutorial Script (avtutorial) 1.0 does not require authentication or knowledge of an old password for password changes, which allows remote attackers to change passwords for arbitrary users via a modified password parameter.
