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 scripting (XSS) vulnerability in the 'Certificate' feature of totemomail 6.0.0 build 570 allows remote attackers to inject arbitrary web script or HTML.

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 installed Totemomail versionLocate the Totemomail installation directory and check the version information file, or run the version command provided by Totemomail (typically found in the admin interface or via command line tool such as 'totemomail --version' or checking the About section in the admin panel)Affected if The installed version is exactly 6.0.0 build 570 (or any 6.0.0 variant)
-
Confirm Certificate feature is enabledAccess the Totemomail admin interface and navigate to the Certificate feature/module. Check if the feature is listed as active or accessible in the feature management or module status sectionAffected if The Certificate feature is enabled and accessible to users
-
Inspect Certificate functionality for user input fieldsIn the web interface, access the Certificate feature and identify all input fields where users can submit data (such as certificate name, description, or metadata fields). These are the potential injection points for XSSAffected if The Certificate feature contains user-supplied input fields that are not visibly sanitized
-
Check HTTP response headers for security headersUse browser developer tools or a command-line tool (curl) to capture HTTP responses from the Certificate feature pages. Examine if Content-Type and X-Content-Type-Options headers are properly set, and look for any reflected user input in the response bodyAffected if User input from Certificate fields appears reflected in the HTML response without encoding
-
Review application logs for XSS indicatorsExamine Totemomail log files (typically found in the logs directory) for entries containing script tags, alert() calls, or other XSS patterns that may indicate exploitation attemptsAffected if Logs contain suspicious patterns consistent with XSS exploitation attempts against the Certificate feature
A user is affected if they are running Totemomail version 6.0.0 with the Certificate feature enabled and accessible, where unsanitized user input in Certificate functionality can be exploited for XSS.

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 dataApply vendor patch for CVE-2018-15510; until then, disable or restrict access to the Certificate feature, and implement output encoding/validation on all user-supplied data in the Certificate module.
