parisneo/lollms Local File Inclusion (LFI) attack

Critical severity GitHub Reviewed Published Jun 12, 2024 to the GitHub Advisory Database • Updated Jun 12, 2024

Package

pip lollms (pip)

Affected versions

< 9.5.0

Patched versions

9.5.0

Description

parisneo/lollms version 9.5 is vulnerable to Local File Inclusion (LFI) attacks due to insufficient path sanitization. The sanitize_path_from_endpoint function fails to properly sanitize Windows-style paths (backward slash \), allowing attackers to perform directory traversal attacks on Windows systems. This vulnerability can be exploited through various routes, including personalities and /del_preset, to read or delete any file on the Windows filesystem, compromising the system's availability.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
