CVE-2017-7725: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
(updated )
concrete5 8.1.0 places incorrect trust in the HTTP Host header during caching, if the administrator does not define a “canonical” URL on installation of concrete5 using the “Advanced Options” settings. Remote attackers can make a GET request with any domain name in the Host header; this is stored and allows for arbitrary domains to be set for certain links displayed to subsequent visitors, potentially an XSS vector.
