Researchers from Tenable recently discovered critical security vulnerabilities in Microsoft’s Azure Health Bot Service [1] [2], posing potential risks of unauthorized access and privilege escalation.
Description
These vulnerabilities were identified in the “Data Connections” feature [1] [2], specifically within the Fast Healthcare Interoperability Resources (FHIR) endpoint [2]. This allowed bots to interact with external data sources and bypass filters through server-side request forgery (SSRF) [1]. Microsoft promptly addressed these vulnerabilities, known as CVE-2024-38109, in the August 2024 Patch Tuesday release [3]. Another privilege escalation vulnerability in the Data Connections feature was also swiftly resolved by Microsoft. The importance of robust web application and cloud security measures for AI-powered services was highlighted by Tenable researchers. It is crucial to note that the vulnerabilities were related to the underlying architecture of the AI chatbot service, not the AI models themselves [3]. Fortunately, there is no evidence of malicious exploitation of these vulnerabilities.
Conclusion
The swift response from Microsoft in addressing these vulnerabilities underscores the importance of proactive security measures in AI-powered services. Organizations should prioritize implementing robust security protocols to safeguard against potential threats and vulnerabilities in cloud-based applications. Moving forward, continuous monitoring and updates are essential to mitigate risks and ensure the security of sensitive data.
