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 · uneditedSES Evolution before 2.1.0 allows deleting some parts of a security policy by leveraging access to a computer having the administration console installed.
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 confidenceSES Evolution before version 2.1.0 contains an improper access control vulnerability where a user with access to a computer running the administration console can delete certain portions of a security policy that they should not have permission to modify. This is a local privilege escalation issue allowing unauthorized policy modification.

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 installed SES Evolution versionOpen the Stormshield Endpoint Security administration console or check the software inventory on the system. Locate the version number of SES Evolution installed.Affected if The installed version is 2.0.0, 2.0.1, or 2.0.2.
-
Confirm administration console accessVerify whether the local or remote administration console for SES Evolution is accessible. Check if the console service is running and reachable.Affected if The administration console is accessible to users who should not have full policy modification rights.
-
Review policy modification permissionsExamine the user access controls within the SES Evolution administration console. Identify which user accounts have permission to modify security policies.Affected if Users with limited privileges can access console functions that allow deletion of policy components they should not be authorized to modify.
-
Audit recent policy changesReview the security policy change logs or audit trail within the SES Evolution console for any unauthorized or unexpected modifications to security policies.Affected if Policy deletions or modifications exist that were made by users lacking proper authorization.
A user is affected if SES Evolution version 2.0.0 through 2.0.2 is installed and the administration console is accessible to users who should not have full policy modification permissions.
