Enterprise Connector v.1.02 Multiple SQL Vulnerabilities and Login Bypass Author: Attila Gerendi (Darkz) Date: December 20, 2005 Package: Enterprise Connector (http://www.enterpriseheart.com/site/modules/mydownloads/) Versions Affected: 1.02 (Other versions may also be affected.) Severity: SQL Injection, Login Bypass Description: Some of this SQL injection vulnerabilities are already reported at: http://secunia.com/advisories/17743/ A new SQL vulnerability not listed in the previous report: Input passed to the "loginid" parameter in "main.php" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code and bypass login sequence. Login Bypass Example: username 'or isnull(1/0) /* password (no password required) or just simply call main.php with POST_PARAMETER loginid='or isnull(1/0) /* Vulnerable code piece: $sql = "SELECT userid, companyid, departmentid, status, languagefile FROM connector_user WHERE "; $sql .= "userid = '" . $_POST['loginid'] . "' "; $sql .= " AND password = '" . $_POST['password'] . "'"; $result = sql_execute($sql); There may be more SQL injection vulnerabilities there. The Author was contacted via home page "contact us" module at December 8 2005, no response given. Solution: Enterprise Connector development seen to be suspended by now. No new release 2004/4/27. You may edit the source code to ensure that input is properly sanitised.
