CVE-2024-27710

Vulnerability

Eskooly Free Online School Management Software version 3.0 and earlier suffers from broken authentication due to insufficient security measures. The application lacks multi-factor authentication (MFA), has a weak password policy, and does not implement account lockout after multiple failed login attempts. This allows attackers to exploit the authentication mechanism [1].

Exploitation

An attacker can perform a brute-force attack against the login endpoint. By capturing the POST request to signin, the attacker can distinguish between a bad password (status code 200, response length between 12169 and 12192) and a correct password (status code 302 Found, response length less than 12169). Without account lockout, the attacker can repeatedly guess passwords until successful [1].

Impact

Successful exploitation grants the attacker unauthorized access to any user account, including administrator accounts. This can lead to data breaches, identity theft, and further malicious activities. The vulnerability allows privilege escalation from a low-privileged user to a higher-privileged role such as admin [1].

Mitigation

As of the publication date, no patched version has been released. Mitigation requires implementing account lockout policies, enforcing strong passwords, and enabling multi-factor authentication. Users should monitor for updates and consider restricting network access to the application [1].
