Twitter User Discloses Second Microsoft Zero-Day

The vulnerability can be used to elevate privileges and delete files on target systems.

Twitter user SandboxEscaper has published a Microsoft Windows zero-day flaw on Twitter, along with a proof-of-concept (PoC) on GitHub, for the second time since August.

This vulnerability affects Microsoft Data Sharing, which manages data handled between applications. Security analysts who analyzed the bug say it can be used to elevate privilege after an attacker gains system access.The PoC shows once they have that access, an attacker would be able to eliminate files that typically require administrative privilege to delete.

All versions of Windows 10, including the most recent update, are affected, in addition to Server 2016 and Server 2019, ZDNet reports. "The Data Sharing Service (dssvc.dll) does not seem to be present on Windows 8.1 and earlier systems," says Will Dormann, vulnerability analyst at the CERT/CC.

SandboxEscaper also used Twitter to disclose a Windows zero-day on Aug. 27. The bug affected the Advanced Local Procedure Call (ALPC) function within the Windows Task Manager in Windows 7 through Windows 10. A local user could use the flaw to gain system privileges.

Two days after the bug was posted on Twitter and its PoC on GitHub, researchers found the exploit in a campaign from the PowerPool threat group. Threat actors modified and recompiled the source code to insert their own malware and gain system privileges in targeted attacks.

0Patch reports it has issued a "micropatch" for the bug in fully updated Windows 10 1803 and in Server 2016.
