Server-Side Request Forgery in HPE AOS-CX

Executive Summary

This vulnerability is a server-side request forgery (SSRF) issue in the web-based management interface of AOS-CX. An authenticated remote attacker can exploit it to send crafted requests from the vulnerable server to internal systems, allowing them to gather details about the internal network structure of the AOS-CX host. This could lead to unauthorized access to sensitive information or limited modification of data.
