It's under active attack, there's no patch, the vendor didn't know etc.- Kevin Beaumont September 8, 2021 Security experts say this flaw appears destined to pose a serious threat for the foreseeable future.ītw, although Microsoft has stopped using the term zero day to describe them in their own products, this one (CVE-2021-40444) is specifically a zero day. It won't help defenders." Flaw Poses Serious Risk "Now is also a great time for security testers and researchers to not be the first to release an exploit, especially pre-patch.

"Now is a great time to remind defenders that they need to focus on comprehensive post-exploitation mitigation and detection," he tweets. These in-the-wild attacks are a reminder that fresh zero-day exploits remain a fact of life, says Andrew Thompson, a threat analyst at Mandiant. He adds: "Since there's no patch, we strongly recommend that Office users be extremely cautious about Office files" and avoid opening any such files from unknown or not fully trusted sources. The exploit uses logical flaws so the exploitation is perfectly reliable (& dangerous).- EXPMON September 7, 2021

We have reproduced the attack on the latest Office 2019 / Office 365 on Windows 10 (typical user environment), for all affected versions please read the Microsoft Security Advisory. Microsoft credits multiple researchers for discovering the flaw: Rick Cole of the Microsoft Threat Intelligence Center Bryce Abdo, Genwei Jiang and Dhanesh Kizhakkinan of Mandiant and Haifei Li of EXPMON, who notes he alerted Microsoft to the problem on Sunday.Ĭode for exploiting the flaw has not yet become public.īut Li tweets that the vulnerability involves "logical flaws" in how MSHTML was built, rather than coding errors that have given rise to attacks based on "memory corruption."

In other words, the greater a user's access rights, the greater the risk posed by a successful attack, since it gives attackers the ability to remotely execute any code on a victim's system. "Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights," Microsoft adds. Unfortunately, as the continuing prevalence of malicious macro attacks demonstrates, this remains a viable attack tactic. Attackers Wield Malicious ActiveX Controlsĭue to the vulnerability, "an attacker could craft a malicious ActiveX control to be used by a Microsoft Office document that hosts the browser rendering engine," after which "the attacker would then have to convince the user to open the malicious document," Microsoft says. While Microsoft has been progressively retiring IE in favor of its newer Edge browser, the MSHTML component continues to be "also used by Microsoft Office," Broadcom's Symantec notes in its own security alert about the flaw.

The newly discovered flaw, designated CVE-2021-40444, exists in MSHTML, aka Trident, which is the HTML engine that's been built into Windows since Internet Explorer debuted more than 20 years ago, and which has allowed Windows to read and display HTML files.

In the meantime, however, its security alert details workarounds and mitigations that it recommends security teams immediately put in place.

Microsoft says its security research team is still probing the flaw, and no full security fixes or patches are yet available, although it's weighing issuing a regular security update as part of its monthly patch-release cycle, or releasing an emergency fix.

Microsoft says in a Tuesday security alert that the remote execution vulnerability exists in MSHTML, and that it "is aware of targeted attacks that attempt to exploit this vulnerability by using specially crafted Microsoft Office documents."
