CVE-2025-6386 Details
Description
The parisneo/lollms repository is affected by a timing attack vulnerability in the `authenticate_user` function within the `lollms_authentication.py` file. This vulnerability allows attackers to enumerate valid usernames and guess passwords incrementally by analyzing response time differences. The affected version is the latest, and the issue is resolved in version 20.1. The vulnerability arises from the use of Python's default string equality operator for password comparison, which compares characters sequentially and exits on the first mismatch, leading to variable response times based on the number of matching initial characters.
A timing attack vulnerability has been identified in the Parisneo Lollms repository, specifically within the authenticate_user function of the lollms_authentication.py file. This vulnerability allows attackers to incrementally guess passwords and enumerate valid usernames by analyzing variations in response times. The issue arises from the use of Python's default string equality operator for password comparisons, which processes characters sequentially and terminates at the first mismatch. As a result, response times vary based on the number of initial matching characters, enabling exploitation. This vulnerability affects the latest version of the lollms repository and has been resolved in version 20.1.
Users can update to version 20.1 of the Parisneo Lollms repository to address this vulnerability.
