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."}, {"lang": "es", "value": "El repositorio parisneo/lollms se ve afectado por una vulnerabilidad de ataque de tiempo en la funci\u00f3n `authenticate_user` del archivo `lollms_authentication.py`. Esta vulnerabilidad permite a los atacantes enumerar nombres de usuario v\u00e1lidos y adivinar contrase\u00f1as de forma incremental mediante el an\u00e1lisis de las diferencias en los tiempos de respuesta. La versi\u00f3n afectada es la m\u00e1s reciente y el problema se ha resuelto en la versi\u00f3n 20.1. La vulnerabilidad surge del uso del operador de igualdad de cadenas predeterminado de Python para la comparaci\u00f3n de contrase\u00f1as, que compara caracteres secuencialmente y finaliza con la primera discrepancia, lo que genera tiempos de respuesta variables seg\u00fan el n\u00famero de caracteres iniciales coincidentes."}], "lastModified": "2025-07-08T16:18:34.923", "sourceIdentifier": "security@huntr.dev"}
