Exchange Is Back on the Menu

Microsoft Exchange has been a recurring topic the last months with continuous problems and fixes being released. This month’s patch Tuesday includes a critical fix for Microsoft Exchange for CVE-2022-23277. A remote code execution vulnerability with a CVSS base score of 8.8. According to Microsoft’s exploitability assessment, this vulnerability’s exploitability is more likely, so quick pathing is recommended.

To exploit the vulnerability, the attacker must be authenticated, additionally, Microsoft lists that «As an authenticated user, the attacker could attempt to trigger malicious code in the context of the server’s account through a network call«.

In addition to the RCE, a spoofing vulnerability has also been disclosed. CVE-2022-24463 with a CVSS base score of 6.5 can lead to file content being exposed. Similar to the RCE, the attacker must be authenticated. To get file content the attacker would have to create a specially crafted network call to the target Exchange Server that causes the parsing of an http request made to an attacker-controlled server.

Video Codec RCE Vulnerabilities

Two video codec extensions offered through the Microsoft Store also contain remote code execution vulnerabilities. The VP9 video extension contains CVE-2022-24501 and the HEVC video extension contains CVE-2022-22006, both with a CVSS base score of 7.8.

The vulnerabilities can be exploited by convincing the user to open a specifically crafted file. Since these vulnerabilities lie in Microsoft Store apps, you’ll have to ensure that you’re not using or have the latest version with a fix installed. For VP9, this means version 1.0.42791.0. For HVEC, if the app is manufacturer pre-installed version 1.0.50361.0 or if you’ve purchased the app, version 1.0.50362.0.

Talking about Microsoft Store apps, Lansweeper 9.3, includes Microsoft Store app scanning, so you’ll be able to find exactly which devices have these apps installed and which version.
