CVE-2022-50900Public exploit

LocalSystem code execution via unquoted service path

Published Jan 13, 2026 · Updated Jan 13, 2026

Unquoted service path in Wondershare Dr.Fone 12.0.18 allows local users to execute arbitrary code with LocalSystem privileges. The Wondershare InstallAssist service registers its automatic LocalSystem executable path without surrounding quotation marks. The referenced service path contains no whitespace, however, so the published artifact does not demonstrate an ambiguous executable search or successful code execution.
