CVE-2017-7725 EXPLOIT
6.1
MEDIUM · CVSS 3.1 · EPSS 2.8% (pctl 86)
Patch early
A public exploit exists.
Description
concrete5 8.1.0 places incorrect trust in the HTTP Host header during caching, if the administrator did 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.
