manage_user_page.php in Mantis 1.00rc4 and earlier does not properly handle a sort parameter containing a ' (quote) character, which allows remote attackers to trigger a SQL error that may be repeatedly reported to a user who makes subsequent web accesses with the MANTIS_MANAGE_COOKIE cookie. NOTE: this issue might be the same as vector 2 in CVE-2005-4519.

Multiple SQL injection vulnerabilities in the manage user page (manage_user_page.php) in Mantis 1.0.0rc3 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) prefix and (2) sort parameters to the manage user page (manage_user_page.php), or (3) the sort parameter to view_all_set.php.
