CVE-2022-20797
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 Secure Network Analytics, formerly Cisco Stealthwatch Enterprise, could allow an authenticated, remote attacker to execute arbitrary commands as an administrator on the underlying operating system. This vulnerability is due to insufficient user input validation by the web-based management interface of the affected software. An attacker could exploit this vulnerability by injecting arbitrary commands in the web-based management interface. A successful exploit could allow the attacker to make configuration changes on the affected device or cause certain services to restart unexpectedly.
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.

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 Cisco Secure Network Analytics installationLocate the installation directory or check system services for Cisco Secure Network Analytics (formerly Stealthwatch). On Linux, check common paths like /opt/cisco/sna/ or look for the 'sna' service process.Affected if The software is installed and running on the system
-
Determine installed versionCheck the version of Cisco Secure Network Analytics. This can typically be found in the web management interface under Help > About, or via CLI if available, or by inspecting version files in the installation directory.Affected if The installed version is lower than 7.4.1 (e.g., 7.3.x, 7.2.x, etc.)
-
Verify web-based management interface accessibilityConfirm the web management interface is reachable. Check if TCP ports (commonly 443 or 8443) for the management UI are listening and accessible from the network.Affected if The web management interface is exposed and reachable from network segments where untrusted users could authenticate
-
Confirm authentication to management interface is possibleVerify that valid credentials exist for the management interface and that user authentication is not restricted to localhost only or VPN-only access.Affected if Attacker can obtain valid credentials to authenticate to the web interface
The environment is affected if Cisco Secure Network Analytics version is below 7.4.1 AND the web-based management interface is accessible to an authenticated attacker who can inject commands through user-supplied parameters.

dbcve · scoped7.4.1
Apply Cisco's security patch for this vulnerability and restrict access to the management interface to authorized personnel only using network segmentation and strong authentication.
7.4.1
- 1. Check the current version of Cisco Secure Network Analytics by accessing the web-based management interface or using the system console.
- 2. If the current version is below 7.4.1, plan for an upgrade during a scheduled maintenance window.
- 3. Back up the current system configuration and data according to Cisco backup procedures for Secure Network Analytics.
- 4. Download Cisco Secure Network Analytics version 7.4.1 or later from the Cisco software download portal (software.cisco.com).
- 5. Follow the Cisco upgrade guide for Secure Network Analytics to install version 7.4.1, ensuring all prerequisites are met.
- 6. After upgrade completion, verify the new version is 7.4.1 or later via the web-based management interface.
- 7. Validate that the web-based management interface is functioning properly and test that command injection is no longer possible.
