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.
-
Confirm HGiga MailSherlock installationIdentify if the HGiga Oaklouds Mailsherlock product is installed in your environment by checking installed software, services, or product documentation.Affected if The product is present and running in the environment.
-
Check installed versionLocate and verify the version number of the MailSherlock installation. Consult the product's about page, version info, or installation directory for version metadata.Affected if The installed version is exactly 4.5.
-
Verify administrator access configurationDetermine whether administrator-level accounts exist and are enabled for the MailSherlock system. Check user management settings or authentication configuration.Affected if Administrator accounts are configured and accessible.
-
Confirm mail query function availabilityIdentify whether the mail query function/module is accessible in the deployment. Check the web interface, API endpoints, or administrative console for this feature.Affected if The mail query function is exposed and functional.
-
Review database interaction logsExamine application logs, database audit trails, or web access logs for unusual or unexpected SQL syntax in mail query operations.Affected if Logs show SQL syntax anomalies or unauthorized database queries.

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 proper input validation and use parameterized queries (prepared statements) for all database interactions in the mail query function. Apply any available vendor patches and follow the principle of least privilege for administrative accounts.
