CVE-2025-48372

Schule is open-source school management system software. The generateOTP() function generates a 4-digit numeric One-Time Password (OTP). Prior to version 1.0.1, even if a secure random number generator is used, the short length and limited range (1000–9999) results in only 9000 possible combinations. This small keyspace makes the OTP highly vulnerable to brute-force attacks, especially in the absence of strong rate-limiting or lockout mechanisms. Version 1.0.1 fixes the issue.

Summary		(es) Schule es un software de gestión escolar de código abierto. La función generateOTP() genera una contraseña de un solo uso (OTP) numérica de 4 dígitos. Antes de la versión 1.0.1, incluso utilizando un generador de números aleatorios seguro, la corta longitud y el rango limitado (1000-9999) resultaban en solo 9000 combinaciones posibles. Este pequeño espacio de claves hace que la OTP sea muy vulnerable a ataques de fuerza bruta, especialmente en ausencia de mecanismos de limitación de velocidad o bloqueo robustos. La versión 1.0.1 corrige este problema.
