Mantis is a PHP/MySQL/Web based bugtracking system.
Antonio Parata and Francesco Ongaro reported a Cross-Site Request Forgery vulnerability in manage_user_create.php (CVE-2008-2276), a Cross-Site Scripting vulnerability in return_dynamic_filters.php (CVE-2008-3331), and an insufficient input validation in adm_config_set.php (CVE-2008-3332). A directory traversal vulnerability in core/lang_api.php (CVE-2008-3333) has also been reported.
A remote attacker could exploit these vulnerabilities to execute arbitrary HTML and script code, create arbitrary users with administrative privileges, execute arbitrary PHP commands, and include arbitrary files.
There is no known workaround at this time.
All Mantis users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/mantisbt-1.1.2"
