CVE-2024-32964 in lobe-chat
Summary
by MITRE • 05/14/2024
Lobe Chat is a chatbot framework that supports speech synthesis, multimodal, and extensible Function Call plugin system. Prior to 0.150.6, lobe-chat had an unauthorized Server-Side Request Forgery vulnerability in the /api/proxy endpoint. An attacker can construct malicious requests to cause Server-Side Request Forgery without logging in, attack intranet services, and leak sensitive information.

The vulnerability identified as CVE-2024-32964 affects Lobe Chat, a comprehensive chatbot framework designed to support speech synthesis, multimodal interactions, and extensible function call plugin systems. This framework serves as a foundational platform for building conversational AI applications, making its security implications particularly significant for organizations relying on chatbot infrastructure. The vulnerability exists within the /api/proxy endpoint of the application, which serves as a critical interface for handling external communications and API integrations. Prior to version 0.150.6, this endpoint failed to properly validate or sanitize incoming requests, creating a dangerous pathway for malicious actors to exploit the system's network connectivity. The flaw represents a serious security oversight that undermines the fundamental trust model of the application's API architecture.
The technical implementation of this Server-Side Request Forgery vulnerability stems from inadequate input validation mechanisms within the proxy endpoint. Attackers can craft malicious HTTP requests that bypass authentication requirements and leverage the application's legitimate network access to make unauthorized requests to internal services. This vulnerability specifically allows attackers to target intranet resources that would normally be protected by network segmentation and firewall policies. The flaw operates at the application layer where the proxy endpoint accepts external requests and forwards them to target destinations without proper validation of the destination URLs or request parameters. This creates a scenario where an attacker can potentially access internal systems, databases, or services that are not directly exposed to the internet but are reachable through the vulnerable proxy mechanism. The vulnerability's classification aligns with CWE-918, which describes server-side request forgery vulnerabilities that enable attackers to make requests to arbitrary destinations.
The operational impact of this vulnerability extends beyond simple information disclosure to encompass potential system compromise and data exfiltration capabilities. An attacker exploiting this vulnerability can gain unauthorized access to internal network resources, potentially including internal APIs, databases, or other sensitive services that are part of the organization's infrastructure. The ability to attack intranet services without authentication creates a significant risk for organizations that rely on Lobe Chat for their conversational AI implementations, particularly in enterprise environments where network segmentation is critical for security. The vulnerability's exploitation can lead to reconnaissance activities where attackers map internal network topology, identify sensitive systems, and potentially escalate privileges through subsequent attacks. This represents a critical threat vector that could enable attackers to move laterally within networks and access confidential information that should remain protected from external access.
Organizations utilizing Lobe Chat must implement immediate mitigations to address this vulnerability, with the most critical step being the upgrade to version 0.150.6 or later. The remediation process should include comprehensive network monitoring to detect any signs of exploitation attempts and proper access controls to limit the attack surface. Security teams should also implement network segmentation policies that prevent the proxy endpoint from accessing internal services unnecessarily. Additional mitigations include implementing strict input validation for all proxy requests, establishing proper rate limiting to prevent abuse, and conducting thorough security testing of all API endpoints. The vulnerability's characteristics align with ATT&CK technique T1071.004, which describes application layer protocol usage for command and control communications, making it essential for security operations centers to monitor for unusual proxy traffic patterns. Organizations should also consider implementing web application firewalls to filter malicious requests and establish incident response procedures specifically designed to handle server-side request forgery attacks. The vulnerability underscores the importance of secure coding practices and proper input validation in API development, particularly for applications that serve as intermediaries between external users and internal systems.
