CVE-2024-7108 Overview
CVE-2024-7108 is an Incorrect Authorization vulnerability [CWE-863] in National Keep Cyber Security Services CyberMath. The flaw allows authenticated local users to access functionality that is not properly constrained by Access Control Lists (ACLs). Affected versions include all CyberMath releases prior to CYBM.240816253.
The weakness stems from missing or incomplete authorization checks on protected functionality. An attacker with low-privilege local access can invoke operations reserved for higher-privileged roles, leading to unauthorized read or modification of restricted resources.
Critical Impact
Authenticated low-privilege users can bypass ACL restrictions and reach functionality intended for privileged roles, resulting in confidentiality and integrity exposure across the CyberMath application.

Technical Details for CVE-2024-7108
Vulnerability Analysis
The vulnerability is classified under [CWE-863]: Incorrect Authorization. CyberMath fails to correctly enforce authorization decisions when an authenticated user requests access to specific application functionality. The application performs authentication but does not consistently validate that the calling principal possesses the required role or permission for the requested action.
Exploitation requires local access and low privileges. No user interaction is needed. A successful attack yields high confidentiality impact within the application scope and limited integrity and availability impact. The EPSS probability is 0.101%, indicating low observed exploitation activity in the wild.
Root Cause
The root cause is missing or insufficient ACL enforcement on privileged code paths. Authorization logic relies on client-controlled state or omits server-side checks before executing sensitive operations. As a result, the application trusts request parameters or session attributes that any authenticated user can supply, instead of revalidating role membership server-side.
Attack Vector
The attack vector is local. A user with valid low-privilege credentials interacts with the CyberMath application and issues requests targeting functionality reserved for administrators or other elevated roles. Because the application does not constrain these requests by ACL, the operation executes with the privileges associated with the function rather than the requester. See the USOM Security Notification TR-24-1549 for vendor-coordinated advisory details.
No public proof-of-concept or exploit code is currently available for CVE-2024-7108.
Detection Methods for CVE-2024-7108
Indicators of Compromise
- Authenticated users accessing administrative endpoints or functionality outside their assigned role scope within CyberMath.
- Unexpected modifications to records, configuration, or user permissions performed by accounts that should lack such rights.
- Application logs showing successful execution of privileged operations without a corresponding role-elevation event.
Detection Strategies
- Audit CyberMath application logs for requests to privileged routes initiated by non-privileged session identifiers.
- Compare the requesting user's role against the sensitivity of executed actions and alert on mismatches.
- Deploy server-side request monitoring that records the authorization decision alongside each privileged action.
Monitoring Recommendations
- Forward CyberMath application and authentication logs to a centralized SIEM for correlation with identity events.
- Establish a baseline of normal per-role activity and flag deviations such as low-privilege accounts invoking admin functions.
- Review user-account-to-action mappings weekly until the patched version is deployed.
How to Mitigate CVE-2024-7108
Immediate Actions Required
- Upgrade CyberMath to version CYBM.240816253 or later, which contains the vendor fix.
- Inventory all CyberMath deployments and confirm version status across environments.
- Review existing user accounts and remove unnecessary local access to systems running CyberMath.
Patch Information
National Keep Cyber Security Services has released a fixed build identified as CYBM.240816253. All earlier versions are affected. Refer to the USOM Security Notification TR-24-1549 for the official advisory and remediation guidance.
Workarounds
- Restrict local access to CyberMath hosts to trusted administrators until patching is complete.
- Apply the principle of least privilege to all CyberMath user accounts and disable inactive accounts.
- Increase logging verbosity on the application to capture authorization decisions for forensic review.
# Verify installed CyberMath version against the patched build
# Replace the path with the actual CyberMath installation directory
grep -i "version" /opt/cybermath/VERSION
# Expected patched value: CYBM.240816253 or later
