The severity of the Spoofing - Windows MSHTML Platform vulnerability (CVE-2024-43461) has increased

The severity of the Spoofing – Windows MSHTML Platform vulnerability (CVE-2024-43461) has increased. The vulnerability was fixed in September Microsoft Patch Tuesday. At the time of publication, Microsoft had not yet flagged this vulnerability as being exploited in the wild. They did this only 3 days later, on September 13.

ZDI Threat Hunting team researcher Peter Girnus discovered the vulnerability while investigating the Void Banshee APT attack. The vulnerability was exploited in the same attack chain as the trending Spoofing – Windows MSHTML Platform (CVE-2024-38112) vulnerability, patched in July.

Using this vulnerability, the attackers hid the extension of the malicious HTA file being opened by adding 26 Braille space characters to its name. Thus, victims may think that they are opening a harmless PDF document.

Installing the security update does not remove spaces in the file name, but Windows now shows the actual file extension. 👍

I found that the research data for Remote Code Execution - Windows Remote Desktop Licensing Service MadLicense (CVE-2024-38077), which I wrote about 3 weeks ago, was deleted

I found that the research data for Remote Code Execution – Windows Remote Desktop Licensing Service “MadLicense” (CVE-2024-38077), which I wrote about 3 weeks ago, was deleted. Both on GitHub and on Google Sites.

And what does this all mean? 🤔 Who knows. 🤷‍♂️ Considering that it disappeared on two platforms at once, it was probably deleted by the Chinese researchers themselves. Why did they do this? Perhaps they established a dialogue with Microsoft and MS asked them to remove everything from the public (which, of course, is stupid – the Internet remembers everything). Perhaps someone else asked them to do this. 🫡 Another reason to pay attention to this vulnerability.

About Elevation of Privilege – Windows Ancillary Function Driver for WinSock (CVE-2024-38193) and other Windows EoP vulnerabilities from August Patch Tuesday

About Elevation of Privilege - Windows Ancillary Function Driver for WinSock (CVE-2024-38193) and other Windows EoP vulnerabilities from August Patch Tuesday

About Elevation of Privilege – Windows Ancillary Function Driver for WinSock (CVE-2024-38193) and other Windows EoP vulnerabilities from August Patch Tuesday. In total, in the August MSPT there were 3 EoPs with signs of exploitation in the wild. They have identical descriptions: an attacker can elevate privileges on the host to SYSTEM level. The vulnerability in Windows Kernel is more difficult to exploit, because it is necessary to win a race condition.

We only know the names of the attackers who exploited the EoP vulnerability in the Windows Ancillary Functions Driver (AFD.sys). It is exploited by the well-known group Lazarus. This was reported in a press release from Gen Digital, the company that owns Avira and Avast antiviruses. To neutralize information security products during an attack, Lazarus attackers use the Fudmodule rootkit. So, even if EDR is installed on the host, the host should be updated. 😏

Progress in exploitation of Remote Code Execution – Windows TCP/IP IPv6 (CVE-2024-38063)

Progress in exploitation of Remote Code Execution - Windows TCP/IP IPv6 (CVE-2024-38063)

Progress in exploitation of Remote Code Execution – Windows TCP/IP IPv6 (CVE-2024-38063). The vulnerability is from the August Patch Tuesday. 2 weeks ago I already wrote why it is potentially dangerous. Now the danger has increased significantly:

🔻 On August 24, a PoC of the exploit appeared on GitHub. There is a video with the launch of a small python script (39 lines), causing Windows to crash with the error “KERNEL SECURITY CHECK FAILURE”. Looks more like DoS than RCE. But this is only for now.

🔻 Well-known researcher Marcus Hutchins posted a blog post titled “CVE-2024-38063 – Remotely Exploiting The Kernel Via IPv6“. It describes the technical details of exploiting the vulnerability.

The probability that the vulnerability will be exploited in the wild has increased significantly.

❗️ Check if the vulnerability is patched or increase the priority of the fix if it is not yet.

Remote Code Execution – Scripting Engine (CVE-2024-38178)

Remote Code Execution - Scripting Engine (CVE-2024-38178)

Remote Code Execution – Scripting Engine (CVE-2024-38178). A vulnerability from the August Microsoft Patch Tuesday. The victim clicks on the attacker’s link, memory corruption occurs and arbitrary attacker’s code is executed.

The tricky part is that the victim has to open the link in Microsoft Edge browser in Internet Explorer compatibility mode. But why would the victim want to set the browser to this mode?

🔻 The victim may be using some old corporate web application that only works in Internet Explorer, so the browser is configured this way. Not such a rare situation. 😏

🔻An attacker may try to convince the victim to enable the setting “Allow sites to be reloaded in Internet Explorer mode (IE mode)” in Edge. 🤷‍♂️

One way or another, the vulnerability is exploited in the wild and there is already a (semi?🤔)public exploit for it. My colleagues at PT ESC shared today how they found and tested this exploit. 🔍
