CVE-2025-48372

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. 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.
