CVE-2024-4841 in lollms-webui
Summary
by MITRE • 06/23/2024
A Path Traversal vulnerability exists in the parisneo/lollms-webui, specifically within the 'add_reference_to_local_mode' function due to the lack of input sanitization. This vulnerability affects versions v9.6 to the latest. By exploiting this vulnerability, an attacker can predict the folders, subfolders, and files present on the victim's computer. The vulnerability is present in the way the application handles the 'path' parameter in HTTP requests to the '/add_reference_to_local_model' endpoint.

The CVE-2024-4841 vulnerability represents a critical path traversal flaw in the parisneo/lollms-webui application that exposes sensitive system information through improper input validation. This vulnerability specifically targets the 'add_reference_to_local_mode' function within the web user interface, where the application fails to adequately sanitize user-provided path parameters. The issue affects all versions from v9.6 through the latest release, indicating a persistent security weakness that has not been adequately addressed in the software lifecycle. The vulnerability exists at the HTTP endpoint '/add_reference_to_local_model' where the application processes incoming requests containing path data without proper validation mechanisms.
The technical exploitation of this vulnerability stems from the application's failure to implement proper input sanitization and validation controls for the path parameter. When an attacker submits malicious path data through the HTTP request to the designated endpoint, the application processes this input without adequate filtering or normalization. This allows attackers to craft specific requests that can traverse the file system hierarchy and enumerate directories and files present on the victim's system. The vulnerability essentially permits arbitrary file system access through predictable path manipulation, enabling attackers to discover system structure and potentially access sensitive files.
From an operational impact perspective, this vulnerability creates significant security risks for organizations utilizing the parisneo/lollms-webui application. The ability to predict and enumerate folders, subfolders, and files provides attackers with detailed reconnaissance information that can be leveraged for further exploitation. This information disclosure vulnerability can serve as a foundation for more sophisticated attacks including privilege escalation, data exfiltration, and system compromise. The vulnerability's presence in the local model reference functionality suggests that attackers could potentially access model files, configuration data, or other sensitive resources stored within the application's file system. This type of information disclosure aligns with CWE-22 Path Traversal vulnerabilities that are classified under the broader category of input validation failures.
The exploitation of this vulnerability demonstrates characteristics consistent with ATT&CK technique T1083 (File and Directory Discovery) where adversaries attempt to gather information about the file system structure. This reconnaissance activity enables attackers to understand system layout and identify potential targets for further compromise. The vulnerability's persistence across multiple versions indicates inadequate security testing and code review processes during the development lifecycle. Organizations should consider implementing network segmentation and access controls to limit exposure, while also recognizing that this vulnerability may be indicative of broader security gaps in the application's architecture.
Security mitigations for CVE-2024-4841 should focus on implementing comprehensive input validation and sanitization measures for all path parameters. The application must validate and normalize all user-provided path data before processing, ensuring that directory traversal sequences are properly filtered or removed. Organizations should immediately upgrade to patched versions of the parisneo/lollms-webui application if available, and implement proper access controls to limit exposure of the vulnerable endpoint. Additionally, network monitoring should be enhanced to detect suspicious path traversal patterns in HTTP requests, and regular security assessments should be conducted to identify similar vulnerabilities in other application components. The vulnerability serves as a reminder of the critical importance of secure coding practices and input validation in preventing information disclosure and privilege escalation attacks.
