CVE-2025-20256
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 Manager and Cisco Secure Network Analytics Virtual Manager could allow an authenticated, remote attacker with valid administrative credentials to execute arbitrary commands as root on the underlying operating system. This vulnerability is due to insufficient input validation in specific fields of the web-based management interface. An attacker with valid administrative credentials could exploit this vulnerability by sending crafted input to an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges.

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 Cisco Secure Network Analytics application on your system or network. This is typically deployed as a virtual appliance or on-premises solution with a web-based management interface.Affected if The product is installed and running.
-
Determine the installed versionAccess the web management interface or use the system's version check command to identify the exact version number of Cisco Secure Network Analytics.Affected if The installed version matches 7.4.1, 7.4.2, 7.5.0, 7.5.1, or 7.5.2.
-
Verify web management interface is accessibleConfirm the web-based management interface is reachable on the network. Check if HTTP/HTTPS ports for the management interface are open.Affected if The web management interface is accessible from the network.
-
Review admin account configurationCheck the list of administrative accounts configured in Cisco Secure Network Analytics. Identify all accounts with admin-level privileges.Affected if Valid admin credentials exist in the system.
-
Audit for suspicious command activityReview system logs, audit logs, and command execution history for unexpected or unauthorized commands, especially those originating from the web management interface.Affected if Unusual commands or suspicious activity is found in logs, particularly commands executed with root privileges.
Your environment is affected if Cisco Secure Network Analytics is installed with version 7.4.1, 7.4.2, 7.5.0, 7.5.1, or 7.5.2 and the web management interface with admin accounts is accessible.
