Résumé
Craft CMS has a host header injection leading to SSRF via resource-js endpoint
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Craft CMS is a content management system (CMS). In versions on the 4.x branch through 4.17.8 and the 5.x branch through 5.9.14, the resource-js endpoint in Craft CMS allows unauthenticated requests to proxy remote JavaScript resources.
When trustedHosts is not explicitly restricted (default configuration), the application trusts the client-supplied Host header. This allows an attacker to control the derived baseUrl, which is used in prefix validation inside actionResourceJs(). By supplying a malicious Host header, the attacker can make the server issue arbitrary HTTP requests, leading to Server-Side Request Forgery (SSRF). Versions 4.17.9 and 5.9.15 patch the issue.
