CVE-2024-6281 in lollms
Summary
by MITRE • 07/20/2024
A path traversal vulnerability exists in the `apply_settings` function of parisneo/lollms versions prior to 9.5.1. The `sanitize_path` function does not adequately secure the `discussion_db_name` parameter, allowing attackers to manipulate the path and potentially write to important system folders.

The vulnerability identified as CVE-2024-6281 represents a critical path traversal flaw within the parisneo/lollms application ecosystem. This security weakness resides in the `apply_settings` function where the `sanitize_path` function fails to properly validate and restrict the `discussion_db_name` parameter. The flaw stems from inadequate input sanitization mechanisms that permit malicious actors to manipulate file paths through crafted input sequences. The vulnerability affects all versions prior to 9.5.1, indicating a regression or oversight in the security implementation that has persisted across multiple releases. This type of vulnerability falls under the common weakness enumeration CWE-22, which specifically addresses path traversal or directory traversal attacks that allow attackers to access files and directories outside the intended scope.
The technical exploitation of this vulnerability enables attackers to manipulate the application's file system operations by injecting malicious path sequences into the `discussion_db_name` parameter. When the application processes these inputs through the `apply_settings` function, the insufficient `sanitize_path` implementation fails to properly validate or normalize the path components, allowing attackers to traverse directories and potentially write to critical system folders. This path traversal capability can be leveraged to overwrite configuration files, inject malicious code, or access sensitive data stored outside the application's designated directories. The vulnerability essentially bypasses the intended file system access controls and creates an attack surface where arbitrary file system operations can be performed with the privileges of the running application.
The operational impact of CVE-2024-6281 extends beyond simple unauthorized file access, as it can potentially lead to complete system compromise when combined with other attack vectors. Attackers could exploit this vulnerability to escalate privileges, install backdoors, or exfiltrate sensitive information from the system. The vulnerability's presence in the discussion database management functionality suggests that it could affect user data persistence and application configuration integrity. Given that this vulnerability allows for arbitrary file system manipulation, it could enable attackers to modify application binaries, configuration files, or even system-level components depending on the application's execution privileges. This makes the vulnerability particularly dangerous in environments where the application runs with elevated permissions or in multi-tenant systems where user data isolation is critical.
Mitigation strategies for CVE-2024-6281 should prioritize immediate remediation through the deployment of version 9.5.1 or later, which includes the necessary fixes to the `sanitize_path` function. Organizations should implement comprehensive input validation measures that enforce strict path normalization and reject any input containing path traversal sequences such as double dots or forward slashes. The application should implement a whitelist-based approach for path validation, ensuring that all file operations occur within explicitly defined and restricted directories. Additionally, the principle of least privilege should be enforced by running the application with minimal necessary permissions and implementing proper file system access controls. Security teams should monitor for any signs of exploitation attempts and consider implementing file integrity monitoring solutions to detect unauthorized modifications to critical system files. The vulnerability's classification under ATT&CK technique T1059.007 for path traversal attacks underscores the need for defensive measures that specifically address file system access control violations.
