parisneo/lollms-webui: Improper Neutralization of Special Elements used in a Command
CVE-2024-2366 is a critical-severity improper neutralization of special elements used in a command vulnerability in parisneo/lollms-webui from ParisNeo, with a CVSS 3.0 base score of 9.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected parisneo/lollms-webui versions: latest and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.66% chance of exploitation within 30 days, higher than 52% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Lollms Web UI to 9.5 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
A remote code execution vulnerability exists in the parisneo/lollms-webui application, specifically within the reinstall_binding functionality in lollms_core/lollms/server/endpoints/lollms_binding_infos.py of the latest version. The vulnerability arises due to insufficient path sanitization, allowing an attacker to exploit path traversal to navigate to arbitrary directories. By manipulating the binding_path to point to a controlled directory and uploading a malicious __init__.py file, an attacker can execute arbitrary code on the server.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
