**Name of the Vulnerable Software and Affected Versions** Schule versions prior to 1.0.1 **Description** The issue concerns a lack of proper rate limiting controls in the file forgot password.php, which is responsible for email-based OTP generation. This allows attackers to abuse the OTP request functionality, potentially leading to denial-of-service (DoS) conditions or facilitating user harassment through email flooding. **Recommendations** For versions prior to 1.0.1, update to version 1.0.1 to resolve the issue. As a temporary workaround, consider implementing rate limiting controls on the forgot password.php file or equivalent endpoint to minimize the risk of exploitation. Restrict access to the forgot password.php file to prevent abuse of the OTP request functionality until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Schule versions prior to 1.0.1 **Description** The issue concerns the generateOTP() function, which generates a 4-digit numeric One-Time Password (OTP) with a limited range of 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. **Recommendations** For versions prior to 1.0.1, update to version 1.0.1 to fix the issue. As a temporary workaround, consider implementing strong rate-limiting or lockout mechanisms to minimize the risk of exploitation. Restrict access to the generateOTP() function until the issue is resolved.

**Name of the Vulnerable Software and Affected Versions** Schule versions prior to 1.0.1 **Description** The issue concerns the Schule open-source school management system software, which relies on client-side JavaScript to redirect users to different panels based on their role. This implementation poses a security risk because it assumes the value of `data.role` is trustworthy on the client side. Attackers can manipulate JavaScript in the browser and set `data.role` to any arbitrary value, gaining unauthorized access to restricted areas of the application. **Recommendations** For versions prior to 1.0.1, update to version 1.0.1 or later to resolve the issue. As a temporary workaround, consider implementing server-side validation of user roles to prevent unauthorized access. Restrict access to sensitive areas of the application until the update is applied.
