Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Always invoking the reference monitor prevents missing authorization checks for protected resources.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Requiring authorization servers ensures authorization is performed for protected functions.
Tailoring determines which functions require authentication and selects the appropriate baseline or compensating authentication controls.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Missing authentication on public web endpoints directly enables T1190 exploitation of a public-facing application; exposure of plaintext passwords facilitates T1552 unsecured credential access.
NVD Description
Missing authentication in /admin/student.php and /admin/teacher.php in ProjectWorlds Online Time Table Generator 1.0 allows remote attackers to obtain sensitive information (including plaintext password field values) via direct HTTP GET requests to these endpoints without a valid session.
Deeper analysisAI
CVE-2025-70147 is a missing authentication vulnerability in the /admin/student.php and /admin/teacher.php endpoints of ProjectWorlds Online Time Table Generator 1.0. Published on 2026-02-18, it stems from CWE-306 (Missing Authentication for Critical Function) and CWE-862 (Missing Authorization), allowing remote attackers to access sensitive information, including plaintext password field values, via direct HTTP GET requests without a valid session. The issue carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting high confidentiality impact with low attack complexity and no privileges required.
Remote attackers on the network can exploit this vulnerability without authentication, user interaction, or special privileges. By issuing unauthenticated GET requests to the affected admin endpoints, they can directly retrieve sensitive data such as plaintext passwords and other student or teacher details from the application, enabling potential further compromise like account takeover or data exfiltration.
