Description

An unauthenticated server-side request forgery (SSRF) vulnerability in the Thumbnail via-uri endpoint of Halo CMS 2.21 allows a remote attacker to cause the server to issue HTTP requests to attacker-controlled URLs, including internal addresses. The endpoint performs a server-side GET to a user-supplied URI without adequate allow/blocklist validation and returns a 307 redirect that can disclose internal URLs in the Location header.

Attack-Flow Graph

Executive Summary

This vulnerability is an unauthenticated server-side request forgery (SSRF) in the Thumbnail via-uri endpoint of Halo CMS 2.21. It allows a remote attacker to make the server send HTTP requests to URLs controlled by the attacker, including internal network addresses. The endpoint performs a server-side GET request to a user-supplied URI without proper allow/blocklist validation and returns a 307 redirect that can reveal internal URLs in the Location header.

Impact Analysis

An attacker can exploit this vulnerability to make the server send requests to internal or external URLs of their choosing, potentially accessing internal services or sensitive information. Additionally, the 307 redirect response can disclose internal URLs, which may aid further attacks or reconnaissance.
