CVE-2024-0759 in anything-llm
Summary
by MITRE • 02/27/2024
Should an instance of AnythingLLM be hosted on an internal network and the attacked be explicitly granted a permission level of manager or admin, they could link-scrape internally resolving IPs of other services that are on the same network as AnythingLLM.
This would require the attacker also be able to guess these internal IPs as `/*` ranging is not possible, but could be brute forced.
There is a duty of care that other services on the same network would not be fully open and accessible via a simple CuRL with zero authentication as it is not possible to set headers or access via the link collector.

CVE-2024-0759 represents a significant information disclosure vulnerability within AnythingLLM, a platform designed for managing and processing large language model interactions. This vulnerability stems from inadequate network segmentation and access control mechanisms that allow authenticated users with manager or admin privileges to perform link-scraping operations that reveal internal network infrastructure. The flaw specifically manifests when an AnythingLLM instance operates within an internal network environment, creating a potential attack vector that could expose sensitive internal services and their associated IP addresses. The vulnerability operates under the principle of lateral movement through network reconnaissance, where authorized users can leverage their elevated permissions to gather intelligence about adjacent network resources.
The technical implementation of this vulnerability involves the link-scraping functionality that is typically designed for external content collection but can be abused to traverse internal network boundaries. When an attacker with manager or admin level access utilizes the link-scraping feature, they can resolve internal IP addresses of services that exist on the same network segment as the AnythingLLM instance. This behavior creates a direct pathway for attackers to enumerate internal network topology and identify potential targets for further exploitation. The vulnerability's impact is amplified by the fact that while the attacker cannot perform wildcard IP range scans, they can still brute force specific IP addresses, making the attack surface more manageable for reconnaissance purposes. This aligns with CWE-200 (Information Exposure) and represents a classic case of insufficient access control in network communication components.
The operational impact of this vulnerability extends beyond simple information disclosure, as it enables attackers to map internal network infrastructure and identify potential targets for additional attacks. The attack requires the attacker to first gain manager or admin level access, which represents a significant privilege escalation requirement, but once achieved, provides access to internal network topology information that could facilitate further compromise. The vulnerability's exploitation is constrained by the need for the attacker to guess internal IP addresses, but this limitation does not prevent the possibility of successful brute force attempts against common internal network ranges. Organizations using AnythingLLM in internal network environments face the risk that their network infrastructure could be mapped by unauthorized users, potentially exposing services that should remain protected from external access. This vulnerability directly conflicts with fundamental security principles of network segmentation and least privilege access control.
The mitigation strategies for CVE-2024-0759 should focus on implementing robust network segmentation and access control measures to prevent lateral movement within internal networks. Organizations should enforce strict access controls that limit the ability of authenticated users to perform network reconnaissance operations, particularly those that could expose internal network topology. The platform should implement additional validation mechanisms to prevent link-scraping operations from accessing internal network resources, including the implementation of network isolation controls and the restriction of network access based on user permissions. Security measures should include disabling or heavily restricting internal IP resolution capabilities for link-scraping functions, implementing proper firewall rules that prevent internal network traversal, and ensuring that the platform does not provide unauthorized access to internal network resources through its core functionalities. The implementation of these controls aligns with ATT&CK technique T1046 (Network Service Scanning) and addresses the fundamental security principle of preventing unauthorized network reconnaissance and information gathering. Organizations should also consider implementing monitoring and alerting mechanisms to detect unusual link-scraping activities that could indicate exploitation attempts.
