CVE-2024-38206 describes an Information Disclosure vulnerability within Microsoft Copilot Studio. This flaw allows an authenticated attacker to circumvent Server-Side Request Forgery (SSRF) protections, potentially exposing sensitive data accessible over the network. The vulnerability impacts versions of Copilot Studio prior to a patch being released, and Microsoft is expected to provide an update soon.
The core impact of CVE-2024-38206 lies in the potential for unauthorized information disclosure. By bypassing SSRF protections, an attacker can craft requests that cause Copilot Studio to access internal network resources or external services it shouldn't. This could lead to the leakage of sensitive data such as API keys, database credentials, internal IP addresses, or even confidential business information. The attacker needs to be authenticated within the Copilot Studio environment to exploit this vulnerability, but once authenticated, the blast radius can be significant, potentially impacting the entire network infrastructure accessible from the Copilot Studio instance.
CVE-2024-38206 was publicly disclosed on August 6, 2024. The vulnerability's SSRF nature suggests a potential for exploitation similar to other SSRF vulnerabilities, where attackers leverage internal network access to gain further access or exfiltrate data. Currently, there are no publicly available proof-of-concept exploits, but the ease of SSRF exploitation generally means that one is likely to appear. Monitor CISA and Microsoft security advisories for updates and potential KEV listing.
Organizations heavily reliant on Microsoft Copilot Studio for automation and chatbot development are at significant risk. Specifically, deployments with Copilot Studio integrated with internal systems or sensitive data stores are particularly vulnerable. Shared hosting environments where multiple customers share the same Copilot Studio instance should also be considered at higher risk.
• .NET / Windows: Monitor Copilot Studio application logs for unusual outbound network requests. Use Sysinternals tools like netstat -ano to identify suspicious connections.

Given that a fixed version is not yet available, immediate mitigation strategies are crucial. Implement strict network segmentation to limit the potential impact of a successful SSRF attack. Review and harden Copilot Studio's network configuration, ensuring that only necessary outbound connections are allowed. Consider using a Web Application Firewall (WAF) with SSRF protection rules to block malicious requests. Closely monitor Copilot Studio logs for suspicious activity, particularly requests to unusual or unexpected destinations. After a patched version is released, upgrade Copilot Studio immediately. Verify the upgrade by attempting to trigger an SSRF request and confirming that it is blocked.
