Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in the /cfg web app and diagnostic endpoints. A remote attacker can send a specially crafted HTTP request with a modified HTTP Host header to port 443/TCP and access the /cfg web application, available at port 8443. As a result, a remote non-authenticated attacker can perform SSRF attack and gain access to services in the internal network.
