Multiple cross-site request forgery (CSRF) vulnerabilities in MyBB 1.2.11 and earlier allow remote attackers to (1) hijack the authentication of moderators or administrators for requests that delete threads via a do_multideletethreads action to moderation.php and (2) hijack the authentication of arbitrary users for requests that delete private messages (PM) via a delete action to private.php.

SQL injection vulnerability in inc/datahandlers/pm.php in MyBB before 1.2.12 allows remote authenticated users to execute arbitrary SQL commands via the options[disablesmilies] parameter to private.php.

CRLF injection vulnerability in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k, when running on older PHP interpreters, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

Multiple SQL injection vulnerabilities in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k allow remote authenticated users to execute arbitrary SQL commands via the (1) graph_list parameter to graph_view.php, (2) leaf_id and id parameters to tree.php, (3) local_graph_id parameter to graph_xport.php, and (4) login_username parameter to index.php/login.

graph.php in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k allows remote attackers to obtain the full path via an invalid local_graph_id parameter and other unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k allow remote attackers to inject arbitrary web script or HTML via (1) the view_type parameter to graph.php; (2) the filter parameter to graph_view.php; (3) the action parameter to the draw_navigation_text function in lib/functions.php, reachable through index.php (aka the login page) or data_input.php; or (4) the login_username parameter to index.php.
