  • Zero-Day Vulnerability in Desktop Window Manager (CVE-2021-28310) Used in the Wild | Securelist
    4/14/2021 Zero-day vulnerability in Desktop Window Manager (CVE-2021-28310) used in the wild | Securelist Zero-day vulnerability in Desktop Window Manager (CVE-2021-28310) used in the wild securelist.com/zero-day-vulnerability-in-desktop-window-manager-cve-2021-28310-used-in-the-wild/101898 While analyzing the CVE-2021-1732 exploit originally discovered by the DBAPPSecurity Threat Intelligence Center and used by the BITTER APT group, we discovered another zero-day exploit we believe is linked to the same actor. We reported this new exploit to Microsoft in February and after confirmation that it is indeed a zero-day, it received the designation CVE-2021-28310. Microsoft released a patch to this vulnerability as a part of its April security updates. We believe this exploit is used in the wild, potentially by several threat actors. It is an escalation of privilege (EoP) exploit that is likely used together with other browser exploits to escape sandboxes or get system privileges for further access. Unfortunately, we weren’t able to capture a full chain, so we don’t know if the exploit is used with another browser zero-day, or coupled with known, patched vulnerabilities. The exploit was initially identified by our advanced exploit prevention technology and related detection records. In fact, over the past few years, we have built a multitude of exploit protection technologies into our products that have detected several zero-days, proving their effectiveness time and again. We will continue to improve defenses for our users by enhancing technologies and working with third-party vendors to patch vulnerabilities, making the internet more secure for everyone.
