Full vulnerability record from the local CVENow database.
Description
An issue was discovered in weijiang1994 university-bbs (aka Blogin) in commit 9e06bab430bfc729f27b4284ba7570db3b11ce84 (2025-01-13). A weak verification code generation mechanism combined with missing rate limiting allows attackers to perform brute-force attacks on verification codes without authentication. Successful exploitation may result in account takeover via password reset or other authentication bypass methods.

Un mecanismo débil de generación de códigos de verificación combinado con la falta de limitación de velocidad permite a los atacantes realizar ataques de fuerza bruta en los códigos de verificación sin autenticación. La explotación exitosa puede resultar en la toma de control de la cuenta a través del restablecimiento de contraseña o de otros métodos de omisión de autenticación."
