CVE-2024-6982

Vulnerability

Overview

CVE-2024-6982 is a remote code execution (RCE) vulnerability in the Calculate function of parisneo/lollms version 9.8. The flaw arises because the application uses Python's eval() function to evaluate mathematical expressions within a restricted sandbox. Although the sandbox disables __builtins__ and only permits functions from the math module, the restriction is insufficient [1].

Exploitation

Details

An attacker can bypass the sandbox by leveraging the _frozen_importlib.BuiltinImporter class to load the os module. This technique allows the execution of arbitrary system commands through the eval() call, without requiring prior authentication or special privileges. The attack can be mounted remotely, making it accessible to any unauthenticated user sending crafted requests to the vulnerable endpoint [1][3].

Impact

Successful exploitation grants the attacker the ability to execute arbitrary Python code and system commands on the server hosting LoLLMs. This can lead to full compromise of the application, data exfiltration, and potential lateral movement within the network. The CVSS v3 base score of 8.4 (High) reflects the significant impact on confidentiality, integrity, and availability [1].

Mitigation

The issue is fixed in version 9.10 of LoLLMs. Users should upgrade immediately to the patched version. There is no known workaround that completely mitigates the vulnerability without upgrading. Given the ease of exploitation and high impact, organizations using affected versions should prioritize patching [1][2][3].
