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 · uneditedPotential security vulnerability of Insufficient Access Controls has been identified in ArcSight Management Center (ArcMC) for versions prior to 2.81. This vulnerability could be exploited to allow for insufficient access controls.
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 confidenceInsufficient access controls vulnerability in ArcSight Management Center (ArcMC) affecting versions prior to 2.81. The vulnerability could allow unauthorized users to access functionality or data they should not have permission to access due to missing or inadequate authentication/authorization checks.

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 ArcSight Management Center is installedIdentify if ArcMC is present in the environment by checking for the application or its typical installation directoriesAffected if ArcSight Management Center is found in the environment
-
Determine the installed ArcMC versionLocate the version information through the product's web interface, command-line interface, or version files included with the installationAffected if The installed version cannot be determined or is below 2.81
-
Compare version against affected rangeCompare the discovered version number to the affected range: any version prior to 2.81 is vulnerableAffected if The installed version is less than 2.81 (for example, 2.7, 2.6, or any 2.x version prior to 2.81)
-
Verify access control configurationReview the authentication and authorization settings in the ArcMC administrative interface or configuration files to confirm whether access controls are properly enforcedAffected if Access controls are missing, misconfigured, or allow unauthenticated access to sensitive functions
The environment is affected if the installed ArcSight Management Center version is prior to 2.81, as the insufficient access controls vulnerability exists in those versions.
