CVE-2023-6676
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCross-Site Request Forgery (CSRF) vulnerability in National Keep Cyber Security Services CyberMath allows Cross Site Request Forgery. This issue affects CyberMath: from v1.4 before v1.5.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceCross-Site Request Forgery (CSRF) vulnerability in CyberMath v1.4 allows attackers to trick authenticated users into performing unintended state-changing actions by forging malicious requests. The vulnerability stems from missing or inadequate anti-CSRF protections on sensitive endpoints.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Cybermath versionLocate the installed Cybermath version number (typically found in admin panel, about page, or version file)Affected if The installed version is exactly 1.4 (this is the only affected version)
-
Identify state-changing endpointsLocate forms or API endpoints that perform actions like user management, configuration changes, or data submissionsAffected if Any state-changing endpoint exists in the Cybermath v1.4 installation
-
Inspect forms for anti-CSRF tokensView page source or intercept form submissions to check for hidden CSRF token fieldsAffected if Forms lack hidden CSRF token input fields on sensitive endpoints
-
Check cookie SameSite attributesInspect session cookies using browser developer tools or command-line tools to verify SameSite attribute valuesAffected if Session cookies do not have SameSite=Strict or SameSite=Lax attributes set
-
Verify referer header validationCheck server-side code or configuration for referer/origin header validation on sensitive requestsAffected if Sensitive endpoints do not validate HTTP referer or origin headers
A user is affected if they are running Nationalkeep Cybermath version 1.4 and their installation lacks CSRF tokens on forms, does not use SameSite cookies, and does not validate request origins on state-changing operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImplement anti-CSRF tokens (synchronizer token pattern) or SameSite cookie attributes on all state-changing operations, or upgrade to v1.5 which contains the fix.
CyberMath v1.5
- Backup the current CyberMath installation and database before upgrading
- Download CyberMath version 1.5 from the official vendor source or trusted distribution channel
- Follow the vendor's documented upgrade procedure for CyberMath
- After upgrading, verify that the application is functioning correctly
- Confirm the CSRF protection mechanisms are properly implemented in the upgraded version
