A zero-day vulnerability in Microsoft Office is being actively exploited in the wild, and while there isn’t currently a patch, the software giant has published workarounds to thwart attacks. CVE-2022-30190, also known as “Follina,” is a remote code execution (RCE) vulnerability affecting the Microsoft Support Diagnostic Tool (MSDT) in Windows.
CVE-2022-30190
Microsoft Windows could allow a remote attacker to execute arbitrary code on the system, caused by a flaw in the Support Diagnostic Tool (MSDT) component. By persuading a victim to open specially-crafted content, an attacker could exploit this vulnerability to execute arbitrary code on the system. Microsoft Support Diagnostics Tool (MSDT) is used by support professionals for troubleshooting.
According to the researcher, maldoc retrieves an HTML file from a server using Word’s template feature. The malicious payload is then obtained via the “ms-msdt: //” URI scheme.
The attackers who successfully exploit this vulnerability can run arbitrary code with the privileges of the calling application. The attacker can then install programs, view, change, delete data, or create new accounts in the context allowed by the user’s permissions.
Here are the workaround guidance shared by Microsoft:
