CVE-2025-70147
Published: 18 February 2026
Summary
CVE-2025-70147 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Projectworlds Online Time Table Generator. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 48.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-22 (Publicly Accessible Content).
Deeper analysis
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.

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.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-14 explicitly requires limiting and documenting permitted actions without identification or authentication, directly preventing unauthorized access to sensitive admin endpoints like /admin/student.php and /admin/teacher.php.
AC-22 mandates controlling access to and protecting the confidentiality of publicly accessible content, mitigating the disclosure of sensitive information via unauthenticated GET requests to public web endpoints.
AC-3 requires enforcement of approved authorizations for logical access to system resources, addressing the core failure to restrict access to sensitive data in the vulnerable admin endpoints.
