What is known about the Spoofing - Windows MSHTML Platform (CVE-2024-43573) vulnerability from the October Microsoft Patch Tuesday?

What is known about the Spoofing – Windows MSHTML Platform (CVE-2024-43573) vulnerability from the October Microsoft Patch Tuesday? In fact, just that it is being exploited in the wild. There are no write-ups or public exploits yet. The Acknowledgements section in the Microsoft bulletin is empty. It is not clear who reported it and from whom we can expect details.

ZDI suggested that this could be an additional fix for a similar July vulnerability Spoofing – Windows MSHTML Platform (CVE-2024-38112). The vulnerability type and component are the same. The July vulnerability was about “.url” file handling and was exploited by the APT group Void Banshee to install the Atlantida Stealer malware. Attackers may have bypassed the initial fix, prompting Microsoft to release a new patch. So far, this is only an assumption. But the vulnerability shouldn’t be ignored despite its low CVSS Base score (6.5).

September episode of “In The Trend of VM”: 7 CVEs, fake reCAPTCHA, lebanese pagers, VM and IT annual bonuses. Starting this month, we decided to slightly expand the topics of the videos and increase their duration. I cover not only the trending vulnerabilities of September, but also social engineering cases, real-world vulnerability exploitation, and practices of vulnerability management process. At the end we announce a contest of questions about Vulnerability Management with gifts. 🎁

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. 👍

Trending vulnerabilities of July according to Positive Technologies.

The SecLab film crew went on vacation. Therefore, there was a choice: to skip the episode of “In the trend of VM” about the July vulnerabilities, or to make a video myself. Which is what I tried to do. And from the next episode we will return to SecLab again.

🔻 According to Check Point, attackers use special “.url” files with icons that look like PDF documents. If the user clicks on the file and ignores 2 uninformative warnings, then a malicious HTA application is launched in the outdated Internet Explorer browser built into Windows. 😱 Why in IE? This is all due to the processing of the “mhtml:” prefix in the “.url” file. The July update blocks this. 👍

🔻 Check Point found “.url” samples that could date back to January 2023. According to Trend Micro, the vulnerability is exploited by the APT group Void Banshee to install the Atlantida Stealer malware and collect passwords, cookies and other sensitive data. Void Banshee add malicious “.url” files to archives with PDF books and distribute them through websites, instant messengers and phishing.
