CVE-2021-38137
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 · uneditedCorero SecureWatch Managed Services 9.7.2.0020 does not correctly check swa-monitor and cns-monitor user’s privileges, allowing a user to perform actions not belonging to his role.
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 confidenceCorero SecureWatch Managed Services 9.7.2.0020 contains an Insecure Privilege Management vulnerability (CWE-269) where the system fails to properly enforce role-based access control checks for swa-monitor and cns-monitor user accounts, allowing authenticated users to perform actions outside their assigned role permissions.

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 installed versionUse system inventory or version lookup commands/tools provided by Corero SecureWatch to determine the currently installed version numberAffected if the installed version is exactly 9.7.2.0020
-
Identify monitor user accountsQuery the user account database or examine the user management configuration to list all defined user accounts, specifically looking for accounts named 'swa-monitor' and 'cns-monitor'Affected if either the swa-monitor or cns-monitor account exists in the system
-
Verify role assignments for monitor accountsExamine the role-based access control configuration for the swa-monitor and cns-monitor accounts to determine what permissions and role they have been assignedAffected if these accounts have permissions that exceed standard monitoring role boundaries or have elevated privileges assigned
-
Test access control enforcementLog in using the swa-monitor or cns-monitor account credentials and attempt to perform administrative or configuration actions outside standard monitoring functionsAffected if the authenticated monitor account can successfully execute actions beyond its assigned monitoring role permissions
A user is affected if their Corero SecureWatch Managed Services installation is version 9.7.2.0020 and the swa-monitor or cns-monitor accounts exist with the ability to perform actions outside their intended monitoring role.

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 vendor security patch or upgrade to a patched version; until then, restrict access to monitoring accounts and implement additional compensating controls such as enhanced audit logging.
