Résumé
TCC Bypass via Downloader XPC Service in Sparkle
Description d'origine
La description telle que publiée par la source (souvent en anglais).
The Sparkle framework includes an XPC service Downloader.xpc, by default this service is private to the application its bundled with. A local unprivileged attacker can register this XPC service globally which will inherit TCC permissions of the application.
Lack of validation of connecting client allows the attacker to copy TCC-protected files to an arbitrary location. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission.
This issue was fixed in version 2.7.2
