Description

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

The vulnerability exists due to insufficient validation of user-supplied input in forward proxy configurations. A remote attacker can send a specially crafted HTTP request and trick the web server to initiate requests to arbitrary systems or cause NULL pointer dereference error and crash the web server.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

SSRF if possible for configuration that mix forward and reverse proxy.
