CVE-2025-7958
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 Code Injection vulnerability existed in Trellix Network Security CM and NX. A locally authenticated admin user can execute arbitrary code using the web interface and Alert artifact details.
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 · high confidenceA code injection vulnerability exists in Trellix Network Security CM and NX that allows a locally authenticated admin user to execute arbitrary code through the web interface via Alert artifact details. The vulnerability stems from insufficient input validation/sanitization on alert artifact fields that are processed by the backend, enabling an authenticated attacker to inject and execute arbitrary code on the system.

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 Trellix Network Security product and versionLocate the installed Trellix Network Security CM or NX installation directory and check the version information file, or run 'Product Name --version' from the command line if availableAffected if The installed product is Trellix Network Security CM or NX and the version matches or predates the vendor patch date
-
Verify web interface is accessibleConfirm the Trellix web interface service is running by checking process status or attempting to access the management URL (typically port 443 or 8443)Affected if The web interface service is active and reachable on the network
-
Confirm admin user accounts existCheck the local user database or authentication configuration for admin-level accounts that have web interface accessAffected if At least one locally authenticated admin user account exists with access to the web interface
-
Verify Alert artifact feature is enabledCheck if the Alert or Analysis module that displays alert artifact details is available in the web interface by navigating to the alert management sectionAffected if The Alert artifact details feature is accessible to authenticated admin users in the web interface
A user is affected if they run Trellix Network Security CM or NX with the web interface enabled, have admin accounts configured, and the Alert artifact details feature is accessible to authenticated users, before applying the vendor patch.

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 dataImplement strict input validation and output encoding on all Alert artifact details fields in the web interface. Apply the vendor-supplied patch when available and follow least-privilege principles for admin accounts.
