Attack-Flow Graph

Executive Summary

This vulnerability exists in the chatwoot software up to version 4.11.2, specifically in the Webhooks::Trigger function within the Webhook API component. It involves manipulation of the 'url' argument, which leads to a server-side request forgery (SSRF). This means an attacker can make the server send unauthorized requests to other internal or external systems by exploiting this flaw.

The attack can be launched remotely, and there is a publicly available exploit that might be used to take advantage of this vulnerability.

Impact Analysis

This vulnerability can allow an attacker to perform server-side request forgery, which means the attacker can make the vulnerable server send requests to other systems that it can access. This can lead to unauthorized access to internal services, data leakage, or interaction with internal network resources that are otherwise protected.

Because the exploit is publicly available and the attack can be performed remotely, the risk of exploitation is higher, potentially leading to compromised confidentiality, integrity, and availability of systems.
