Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 49.7th 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 are NIST 800-53 AC-3 (Access Enforcement) and AC-6 (Least Privilege).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

AC-3 requires enforcement of approved authorizations for logical access, directly preventing unauthorized users from accessing and manipulating administrative endpoints like teacher/edit/{id}.

AC-6 Least Privilege good match

prevent

AC-6 enforces least privilege, ensuring only authorized administrators can access sensitive teacher edit functions, mitigating the incorrect access control flaw.

AC-14 Permitted Actions Without Identification or Authentication partial match

prevent

AC-14 limits and documents actions permitted without identification or authentication, countering the vulnerability's allowance of admin operations by unauthenticated users.

NVD Description

Unifiedtransform v2.X is vulnerable to Incorrect Access Control. Unauthorized users can access and manipulate endpoints intended exclusively for administrative use. This issue specifically affects teacher/edit/{id}.

Deeper analysisAI

Unifiedtransform v2.X, an open-source school management system, is affected by CVE-2024-53573, an incorrect access control vulnerability classified under CWE-284. The flaw allows unauthorized users to access and manipulate endpoints intended exclusively for administrative use, with the teacher/edit/{id} endpoint specifically impacted. Assigned a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), it represents a critical risk due to its potential for high-impact unauthorized modifications without requiring authentication or user interaction.

Attackers can exploit this vulnerability remotely over the network with no privileges or special conditions needed. Any unauthenticated user, including external adversaries, can directly access the vulnerable endpoint to view, edit, or delete sensitive teacher information, potentially leading to data tampering, unauthorized privilege escalation within the system, or broader compromise of school administrative functions.
