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 · uneditedWondershare Dr. Fone Latest version as of 2021-12-06 is vulnerable to Incorrect Access Control. A normal user can send manually crafted packets to the ElevationService.exe and execute arbitrary code without any validation with SYSTEM privileges.
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 confidenceWondershare Dr. Fone's ElevationService.exe runs with SYSTEM privileges but lacks proper access control validation. A normal (unprivileged) user can send manually crafted packets directly to this service to execute arbitrary code with elevated privileges, resulting in local privilege escalation.
