CVE-2018-18602
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 · uneditedThe Cloud API on Guardzilla smart cameras allows user enumeration, with resultant arbitrary camera access and monitoring.
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 confidenceThe Guardzilla smart camera Cloud API contains a user enumeration vulnerability that allows attackers to discover valid user accounts through the authentication interface. Once valid usernames are identified, attackers can gain arbitrary access to associated cameras and monitor feeds without proper authorization.

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 Guardzilla Cloud API presenceLocate the Guardzilla authentication endpoint in your environment - typically at api.guardzilla.com or similar cloud URLs used by Guardzilla camerasAffected if Guardzilla devices or cloud services are in use and accessible
-
Verify authentication endpoint accessibilityConfirm the login/authentication API endpoint is reachable - typically a POST request to /api/v1/auth/login or similar authentication routeAffected if The authentication endpoint is exposed and accepts login requests
-
Test for user enumeration with invalid usernameSend a login request with a clearly invalid/nonexistent username (e.g., 'nonexistentuser123') and capture the exact error response messageAffected if API is accessible and returns an error message
-
Test for user enumeration with valid username formatSend a login request using a potentially valid username (e.g., an email address known to be used with Guardzilla) but wrong password, and compare the error message to step 3Affected if Different error messages are returned for valid vs invalid usernames, revealing which accounts exist
-
Check for consistent error responsesCompare authentication failure responses for both valid and invalid usernames - look for differences in HTTP status codes, error text, or response timing that indicate account existenceAffected if The API leaks information about account validity through varying responses
If Guardzilla camera cloud services are in use AND the authentication API returns different responses for valid versus invalid usernames (revealing which accounts exist), the environment is affected by this user enumeration vulnerability.

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 account enumeration protections including generic authentication error messages, rate limiting on login endpoints, account lockout policies, and consider transitioning to non-enumerable user identifiers to prevent user discovery.
