Quote:A researcher has made public technical details, a video and proof-of-concept (PoC) exploit code for an unpatched local privilege escalation (LPE) vulnerability affecting Windows.
 
The flaw, disclosed by a researcher who uses the online moniker SandboxEscaper, is related to discretionary access control lists (DACL) and the Task Scheduler, and the exploit has been confirmed to work reliably on a fully patched Windows 10 machine, including 64-bit systems.
 
The vulnerability allows an attacker with limited privileges to change permissions for a specified file by importing a .job file into the Task Scheduler using schtasks.

SecurityWeek has reached out to Microsoft for comment and will update this article if the company responds. Unless in-the-wild exploitation is detected, the company will likely address the flaw with Patch Tuesday updates.
