CVE-2021-27664
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 · uneditedUnder certain configurations an unauthenticated remote user could be given access to credentials stored in the exacqVision Server.
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 confidenceIn certain configurations, exacqVision Server allows unauthenticated remote attackers to access stored credentials, likely due to an authentication bypass or improper access control on credential storage mechanisms.

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 exacqVision Web Service is installedCheck for exacqVision server software on the system by searching for the application process or service name, typically running as a Windows service or Linux daemon related to exacqVisionAffected if The exacqVision server software is present on the system
-
Determine the installed versionLocate the exacqVision Web Service executable or version information, commonly found in the program's directory, About section, or Windows Programs and Features entry, and compare it to the affected version 20.06.11.0Affected if The installed version is 20.06.11.0 or lower
-
Verify network exposure of the web serviceDetermine if the exacqVision web interface (typically ports 80/443 or 8081/8082) is accessible from untrusted network locations or the internet without requiring authenticationAffected if The web service port is exposed to untrusted networks without proper firewall restrictions or authentication barriers
-
Test for unauthenticated credential accessAttempt to access credential storage endpoints or configuration areas of the exacqVision web interface without providing valid login credentials to confirm if authentication is enforcedAffected if Credential storage mechanisms or sensitive configuration pages are accessible without authentication
-
Review credential storage configurationExamine the exacqVision configuration files or database where credentials are stored to verify that proper access controls and authentication requirements are in placeAffected if Credential storage lacks proper authentication enforcement or access controls
You are affected if exacqVision Web Service version 20.06.11.0 or lower is installed and the credential storage is accessible without authentication due to improper access controls.

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 dataIdentify and remediate the vulnerable configuration settings; restrict network exposure of the exacqVision Server and review credential storage mechanisms to ensure proper authentication is enforced.
