CVE-2024-39713 Scanner

Rocket.Chat is a widely-used, open-source communication platform tailored for teams and organizations that require secure, real-time messaging. It enables collaboration across private and public chat rooms and allows integration with external services through APIs. The software is popular in enterprise environments due to its customization options and extensive support for webhooks and API integrations. Many organizations rely on Rocket.Chat for internal communication, as well as customer support via live chat. Twilio integration, among others, is often leveraged to enable SMS-based notifications and customer interactions.

The Server-Side Request Forgery (SSRF) vulnerability in Rocket.Chat affects the Twilio webhook integration before version 6.10.1. It allows attackers to manipulate requests sent from the server, potentially accessing internal resources. By leveraging the Twilio endpoint, an attacker can control the requests from Rocket.Chat’s server, bypassing network restrictions. The SSRF vulnerability poses a significant risk, as it could expose sensitive information or cause other security incidents.

The SSRF vulnerability resides in the Twilio webhook endpoint, where user input is insufficiently validated, allowing for the insertion of arbitrary URLs. The affected endpoint is /api/v1/livechat/sms-incoming/twilio, where data submitted through the "MediaUrl0" parameter can redirect requests. Attackers can trigger HTTP requests to internal systems by exploiting this parameter, potentially bypassing firewall restrictions. The vulnerability also affects how Rocket.Chat’s backend handles DNS-based requests, exposing it to external interaction attempts. Such behavior, if unchecked, can facilitate reconnaissance or unauthorized access to internal resources.

Exploiting this vulnerability could allow attackers to make requests on behalf of the Rocket.Chat server, potentially exposing internal systems. Attackers may retrieve sensitive data, perform lateral movement within the network, or access unauthorized resources. This vulnerability could enable attackers to bypass firewalls, gain insights into internal network configurations, and access restricted endpoints. Additionally, SSRF attacks may result in unintended resource usage or lead to information disclosure.

Protecting against SSRF vulnerabilities is crucial for organizations to prevent unauthorized access and control over their systems.
