"The version of Microsoft Visual Studio Code installed on the remote
Windows host is prior to 1.48.2. It is, therefore, affected by the
following vulnerability:
- A remote code execution vulnerability exists in Visual
Studio Code when a user is tricked into opening a
malicious 'package.json' file. An attacker who
successfully exploited the vulnerability could run
arbitrary code in the context of the current user. If
the current user is logged on with administrative user
rights, an attacker could take control of the affected
system. An attacker could then install programs; view,
change, or delete data; or create new accounts with full
user rights. To exploit this vulnerability, an
attacker would need to convince a target to clone a
repository and open it in Visual Studio Code. Attacker-
specified code would execute when the target opens the
malicious 'package.json' file. The update address the
vulnerability by modifying the way Visual Studio Code
handles JSON files.");
