| Title | Ryan Cramer ( https://processwire.com/about/team/ryan/ ) ProcessWire CMS 3.0.255 SSRF ( Server-Side Request Forgery ) |
|---|
| Description | The application allows administrators to fetch module ZIP files from arbitrary user-supplied URLs, resulting in a server-side request forgery (SSRF) condition. The server performs outbound requests to internal and external resources without proper validation or restriction. Additionally, verbose error messages disclose whether a target host or port is reachable, enabling internal network enumeration. This behavior can be abused to probe internal services and identify open ports from the server’s perspective. |
