Multiple cross-site scripting (XSS) vulnerabilities in Open Business Management (OBM) 2.4.0-rc13 and probably earlier allow remote attackers to inject arbitrary web script or HTML via the (1) tf_delegation, (2) tf_ip, or (3) tf_name parameter in a search action to host/host_index.php; (4) login parameter to obm.php; or (5) tf_user parameter in a search action to group/group_index.php.
