Authentication bypass in Google Quick Share for Windows unknown-file handling
CVE-2024-10668 is an authentication/session-bypass flaw in Google Quick Share for Windows that allows an attacker to cause an unknown file type to be written to the victim's Downloads folder. According to the provided description, the issue is triggered by sending a Payload Transfer frame of type FILE to Quick Share, which causes the embedded file to be written to disk. Quick Share is intended to delete unknown file types, but the deletion logic can be bypassed by sending two FILE Payload Transfer frames that reuse the same payload ID. In that condition, the cleanup logic deletes only the first file and leaves the second file on disk. The root cause, based on the supplied information, is flawed validation/state handling around duplicate payload IDs and post-write deletion of unapproved file types.
