CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2025-48375 – Schule Missing Rate Limiting on OTP Email Requests – Susceptible to Abuse & DoS
https://notcve.org/view.php?id=CVE-2025-48375
23 May 2025 — Schule is open-source school management system software. Prior to version 1.0.1, the file forgot_password.php (or equivalent endpoint responsible for email-based OTP generation) lacks proper rate limiting controls, allowing attackers to abuse the OTP request functionality. This vulnerability can be exploited to send an excessive number of OTP emails, leading to potential denial-of-service (DoS) conditions or facilitating user harassment through email flooding. Version 1.0.1 fixes the issue. • https://github.com/schule111/Schule/security/advisories/GHSA-h3f2-mc85-67gc • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2025-48373
22 May 2025 — Schule is open-source school management system software. The application relies on client-side JavaScript (index.js) to redirect users to different panels based on their role. Prior to version 1.0.1, this implementation poses a serious security risk because it assumes that the value of data.role is trustworthy on the client side. Attackers can manipulate JavaScript in the browser (e.g., via browser dev tools or intercepting API responses) and set data.role to any arbitrary value (e.g., "admin"), gaining una... • https://github.com/schule111/Schule/commit/cbf7f509c37acd69b4ab8ee19d842de867b46b7e • CWE-863: Incorrect Authorization •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2025-48372 – Schule Has Insecure OTP Length, is Susceptible to Brute-Force Attacks
https://notcve.org/view.php?id=CVE-2025-48372
22 May 2025 — 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. • https://github.com/schule111/Schule/commit/cd53abbea93943f2c60a5281d45bebadc57636b7 • CWE-521: Weak Password Requirements •
