# CVE-2019-1387: Git for Visual Studio Remote Code Execution Vulnerability CVE-2019-1387 is fixed in 20 products on 1 platform, first by git 1:2.17.1-1ubuntu0.5, released December 10, 2019. It is not reported as exploited. Patch Radar priority: Urgent. - Web page: https://patchblox.com/security/cve/CVE-2019-1387 - Priority: Urgent - CVSS: 8.8 (Critical) - EPSS: 0.0443 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Vendor exploitability assessment: Exploitation Less Likely - Published: Dec 10, 2019 - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2019-1387 ## Description

A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

To exploit the vulnerability, an attacker would first need to convince the user to clone a malicious repo.

The security update addresses the vulnerability by correcting how Git for Visual Studio validates command-line input.
