csNews Advanced Settings and administrative access

cgiscript-csnews-admin-access (9333) The risk level is classified as HighHigh Risk


csNews fails to properly handle double URL encoded characters. A remote attacker could exploit this vulnerability by sending a specially-crafted URL request containing double URL encoded characters to access the "Advanced Settings" page, which is normally only accessible by administrators.

Once the attacker gains access to the "Advanced Settings" page, modified values could be set using the header and footer form fields, which could allow the attacker to view arbitrary system files or execute arbitrary system commands.
