Multiple cross-site scripting (XSS) vulnerabilities in Mambo 4.6.x allow remote attackers to inject arbitrary web script or HTML via (1) the query string to (a) index.php, which reflects the string in an error message from modlogin.php; and the (2) mcname parameter to (b) moscomment.php and (c) comcomment.php.

DISPUTED PHP remote file inclusion vulnerability in contentpublisher.php in the contentpublisher component (comcontentpublisher) for Mambo allows remote attackers to execute arbitrary PHP code via a URL in the mosConfigabsolutepath parameter. NOTE: this issue has been disputed by third parties who state that contentpublisher.php protects against direct request in the most recent version. The original researcher is known to be frequently inaccurate.
