footer.php in PunBB 1.2.14 and earlier allows remote attackers to include local files in include/user/ via a cross-site scripting (XSS) attack, or via the pun_include tag, as demonstrated by use of admin_options.php to execute PHP code from an uploaded avatar file.

Multiple cross-site scripting (XSS) vulnerabilities in PunBB 1.2.14 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) Referer HTTP header to misc.php or the (2) category name when deleting a category in admin_categories.php.

include/common.php in PunBB 1.2.14 and earlier does not properly handle a disabled ini_get function when checking the register_globals setting, which allows remote attackers to register global parameters, as demonstrated by an SQL injection attack on the search_id parameter to search.php.

cosign-bin/cosign.cgi in Cosign 2.0.2 and earlier allows remote authenticated users to perform unauthorized actions as an arbitrary user by using CR (r) sequences in the service parameter to inject LOGIN and REGISTER commands with the desired username.

The CHECK command in Cosign 2.0.1 and earlier allows remote attackers to bypass authentication requirements via CR (r) sequences in the cosign cookie parameter.
