Multiple SQL injection vulnerabilities in KnowledgeQuest 2.6, when magic_quotes_gpc is disabled, allow remote attackers to execute arbitrary SQL commands via the (1) kqid parameter to (a) articletext.php and (b) articletextonly.php and the (2) username parameter to (c) logincheck.php.

KnowledgeQuest 2.5 and 2.6 does not require authentication for access to admincheck.php, which allows remote attackers to create arbitrary admin accounts.
