SQL injection vulnerability in password_reminder.php in ATutor before 1.5.1 pl1 allows remote attackers to execute arbitrary SQL commands via the email field.
config.inc.php in ATutor 1.5.1, and possibly earlier versions, uses an incomplete blacklist to check for dangerous file extensions, which allows authenticated administrators or educators to execute arbitrary code by uploading files with other executable extensions such as .inc, .php4, or others.
