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 · unedited
A vulnerability in the web UI of Cisco SD-WAN Solution vManage software could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. The vulnerability exists because the web UI improperly validates SQL values. An attacker could exploit this vulnerability by authenticating to the application and sending malicious SQL queries to an affected system. A successful exploit could allow the attacker to modify values on, or return values from, the underlying database as well as the operating system.

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 confidence

SQL injection vulnerability in the web UI of Cisco SD-WAN vManage allows authenticated attackers to inject malicious SQL queries due to improper validation of SQL values. Successful exploitation enables modification or extraction of database contents and potentially command execution on the underlying operating system.

MitigationApply the Cisco patch for this vulnerability; until then, restrict administrative access to trusted users only and monitor for anomalous SQL queries in web UI logs.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Cisco SD-WAN vManage version
    Access the vManage admin interface or use the CLI command 'show version' to retrieve the installed firmware version. Compare against the affected range of versions prior to 19.2.2.
    Affected if The installed version is lower than 19.2.2
  2. Verify web UI is enabled
    Confirm that the vManage web UI service is running and accessible. Check via CLI with 'show web-server config' or verify the service status.
    Affected if The web UI is exposed and accessible to the network
  3. Confirm authentication is configured
    Check if local or remote authentication (RADIUS/TACACS+) is enabled for vManage admin access. Verify with 'show authentication' CLI command.
    Affected if Admin authentication is enabled (which is required for the authenticated SQL injection to execute)

Your environment is affected if you run Cisco SD-WAN vManage firmware versions prior to 19.2.2 with the web UI accessible and administrative authentication enabled.
