CVE-2020-3339
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 · uneditedA vulnerability in the web-based management interface of Cisco Prime Infrastructure could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. The vulnerability is due to improper validation of user-submitted parameters. An attacker could exploit this vulnerability by authenticating to the application and sending malicious requests to an affected system. A successful exploit could allow the attacker to obtain and modify sensitive information that is stored in the underlying database.

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 Cisco Prime Infrastructure is installedCheck if the Cisco Prime Infrastructure application is present on the system. This is typically deployed as a virtual appliance. Look for the product in your inventory or run 'show version' on the CLI if you have console access.Affected if Cisco Prime Infrastructure software is not found in the environment, this CVE does not apply.
-
Identify the installed versionAccess the web-based management interface and navigate to Home > Settings > Software Updates > Installed Software to view the installed version. Alternatively, log into the CLI and run 'show version' to display the Cisco Prime Infrastructure version.Affected if The installed version is 3.7.1 or lower, or exactly 3.8 - the environment is within the affected version range.
-
Verify web-based management interface is enabledConfirm that the Cisco Prime Infrastructure web-based management interface (HTTP/HTTPS on port 443 or 8080) is active and listening. Check with 'netstat -an | grep -E '443|8080'' or review the running services on the appliance.Affected if The web-based management interface is disabled or not accessible, the SQL injection vulnerability cannot be exploited.
-
Confirm authentication is required for the interfaceVerify that the web management interface requires valid credentials for access. Check if anonymous or unauthenticated access is possible through the interface configuration.Affected if The interface is exposed without authentication, the specific authenticated SQL injection may not apply, but other risks exist.
The environment is affected by CVE-2020-3339 if Cisco Prime Infrastructure is installed with a version <= 3.7.1 or exactly 3.8, and the web-based management interface is accessible to the attacker with valid authentication credentials.

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 the vendor patch from Cisco for this vulnerability. As an interim control, restrict access to the web-based management interface to trusted IP addresses or networks and implement additional input validation at the application layer.
