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.
-
Locate F-RevoCRM installation directoryIdentify the web root directory where F-RevoCRM is installed. Common locations include /var/www/html/, /www/html/, or C:\inetpub\wwwroot\ on Windows servers. Look for directories containing 'frevvo', 'f-revocrm', or 'RevoCRM' in the name.Affected if F-RevoCRM is not found in the expected installation paths, then the product may not be deployed.
-
Determine installed F-RevoCRM versionCheck the version file in the F-RevoCRM installation directory. Common version file names include version.php, About.php, or a config/include file that stores the application version. Alternatively, access the admin About or System Info page in the CRM web interface if available.Affected if The detected version is 7.3.7 or 7.3.8 exactly.
-
Verify exact version matchCompare the discovered version number against the affected versions: 7.3.7 and 7.3.8. Ensure no patches or hotfixes have modified the base version string.Affected if The installed version is exactly 7.3.7 or exactly 7.3.8.
-
Confirm the product access feature is enabledF-RevoCRM is a web-based CRM. Verify that the web application is accessible and user authentication/login functionality is operational. The vulnerability requires an attacker to have product access (valid credentials).Affected if The CRM is running and accepts user authentication, meaning the command injection attack surface is present.
If F-RevoCRM is installed and the version is exactly 7.3.7 or 7.3.8 with user authentication enabled, the environment is affected by this OS command injection 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 dataUpdate to a patched version of F-RevoCRM if available; otherwise, restrict network access to the CRM application and implement strict input validation at all application entry points.
