Synopsis

The Microsoft Visual Studio Products are affected by an information disclosure vulnerability.

Description

The Microsoft Visual Studio Products are missing a security update.
It is, therefore, affected by an information disclosure vulnerability:

- It is possible to obtain a user's NTLM hash by tricking them into cloning a malicious repository, or checking out a malicious branch that accesses an attacker-controlled server. By default, NTLM authentication does not need any user interaction. GitHub created this CVE on their behalf. The documented Visual Studio updates incorporate updates in Git which address this vulnerability.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Microsoft has released the following security updates to address this issue:
- Update to 15.9.79 for Visual Studio 2017 15.9
- Update to 16.11.55 for Visual Studio 2019 16.11
