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.
-
Identify the eExamhall plugin installationLocate the Aarvanshinfotech Online Exam Software installation directory and identify if the eExamhall plugin component is present. Check plugin configuration files, database records, or admin panel plugin listings for eExamhall.Affected if The eExamhall plugin is found in the Online Exam Software installation
-
Determine the installed eExamhall versionInspect the plugin version file, changelog, or admin interface plugin details to obtain the exact version number of the eExamhall plugin.Affected if The installed version is 4.0 or below
-
Inspect state-changing endpoints for anti-CSRF tokensExamine the source code of forms and API endpoints that perform state-changing operations (such as user creation, exam modifications, or result submissions) within the eExamhall plugin. Look for the presence of anti-CSRF token generation and validation logic.Affected if State-changing operations lack anti-CSRF token validation
-
Check SameSite cookie configurationReview the session and authentication cookie settings in the application configuration or code. Inspect Set-Cookie headers to verify if SameSite attributes are properly set.Affected if SameSite cookie attributes are missing, set to None, or not configured
-
Verify Origin and Referer header validationAnalyze the server-side code handling form submissions and API requests to determine if Origin or Referer HTTP headers are validated against an allowlist.Affected if Origin and Referer headers are not validated for state-changing requests
A user is affected if the eExamhall plugin version is 4.0 or below AND state-changing operations lack anti-CSRF token validation, SameSite cookie attributes, and Origin/Referer header validation.

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.
From vendor dataImplement anti-CSRF token validation on all state-changing operations, configure SameSite cookie attributes, and validate Origin/Referer headers to prevent CSRF attacks.
