CVE-2025-70147
Access Control in Projectworlds Online Time Table Generator 1.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
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 at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and AC-24 (Access Control Decisions) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.
Advisories and additional details are available in the referenced sources, including the project page at https://projectworlds.com/online-time-table-generator-php-mysql/ and a technical write-up at https://youngkevinn.github.io/posts/CVE-2025-70147-OTTTG-Info-Disclosure/. Security practitioners should consult these for any guidance on patches or workarounds, as no specific mitigation steps are detailed in the CVE description.

Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly requires enforcement of authorization decisions on every access request, structurally eliminating missing authorization checks.
Directly mandates unique identification and authentication of users before access to functions requiring identity.
Extends the same authentication requirement to non-organizational users accessing critical functionality.
Requires authentication of services before they can invoke or expose critical functions.
Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.
AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.
Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing authorization checks.
Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.
Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
The control explicitly calls for authentication before any critical function is reached, eliminating the possibility of bypassing authentication for high-value operations.
Requiring authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.
Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.
Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.
Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.
By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.
