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 · uneditedZoho ManageEngine ADSelfService Plus before 6218 allows anyone to conduct a Denial-of-Service attack via the Mobile App Authentication API.
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 confidenceZoho ManageEngine ADSelfService Plus versions prior to 6218 contain a denial-of-service vulnerability in the Mobile App Authentication API that allows remote attackers to crash or make the service unavailable. The issue is exploitable without authentication, making it easily weaponizable.

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 ADSelfService Plus versionLocate the product version information in the ADSelfService Plus administration console or check the product build/version file in the installation directoryAffected if The installed version is 4.5, 5.0, 5.0.6, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, or 6.0, or any version prior to 6218
-
Verify Mobile App Authentication API is accessibleCheck whether the Mobile App Authentication API endpoints are exposed and reachable on the ADSelfService Plus serverAffected if The Mobile App Authentication API is enabled and reachable from a network perspective, as the vulnerability is exploitable without authentication
-
Confirm external or internal API exposureReview network configuration and firewall rules to determine if the ADSelfService Plus web interface (particularly the Mobile App API paths) is accessible from untrusted networksAffected if The API is accessible from external networks or untrusted internal segments, as the exploit requires network access to the vulnerable endpoint
A user is affected if their ADSelfService Plus version is prior to 6218 and the Mobile App Authentication API is network-accessible, enabling a remote unauthenticated attacker to cause denial of service.
