Summary

CVE-2025-46203 is a medium-severity Incorrect Privilege Assignment (CWE-266) vulnerability in Changeweb Unifiedtransform. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 24th 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-3 (Access Enforcement) and AC-2 (Account Management) — see the control section below for these in your framework.

Vulnerability Data

An issue in Unifiedtransform v2.0 allows a remote attacker to escalate privileges via the /students/edit/{id} endpoint.

CWE(s)

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1098 Account Manipulation Persistence
Adversaries may manipulate accounts to maintain and/or elevate access to victim systems.
T1565.001 Stored Data Manipulation Impact
Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.
Why these techniques?

Incorrect access control in Unifiedtransform v2.0 allows authenticated low-privileged users (students/teachers) to access the /students/edit/{id} endpoint and modify student records intended for admins only, facilitating exploitation for privilege escalation (T1068), account manipulation (T1098), and stored data manipulation (T1565.001).

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization checks on the /students/edit/{id} endpoint so that only properly assigned users may modify student records.

prevent

Requires that accounts and roles are provisioned with only the minimum privileges needed, reducing the impact of incorrect privilege assignments that enable the escalation.

prevent

Ensures that user accounts and their associated privileges for student data are created, reviewed, and revoked according to defined policy, limiting opportunities for erroneous privilege grants.

PR.AA-05 full match
prevents

Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.

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.

prevents

The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.

prevents

Privileged-access-rights control explicitly requires least-privilege assignment and ongoing validation, directly mitigating CWE-266.

prevents

Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.

mitigates

Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.

mitigates

Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.

prevents

Information-access-restriction mechanisms enforce the correct privilege boundaries once assignment rules are defined.
