Hacker Discloses New Windows Zero-Day Exploit On Twitter

A security researcher with Twitter alias SandboxEscaper—who two months ago publicly dropped azero-day exploit for Microsoft Windows Task Scheduler—has yesterday released another proof-of-concept exploit for a new Windows zero-day vulnerability. SandboxEscaper posted a link to a Github page hosting a proof-of-concept (PoC) exploit for the vulnerability that appears to be a privilege escalation flaw residing in Microsoft Data Sharing (dssvc.dll). The PoC exploit has successfully been tested against “fully-patched Windows 10 system” with the latest October 2018 security updates, Server 2016 and Server 2019, but we do not recommend you to run the PoC, as it could crash your operating system.
