CVE-2019-1211 (GCVE-0-2019-1211)

Vulnerability from cvelistv5 – Published: 2019-08-14 20:55 – Updated: 2024-08-04 18:13

Title

Git for Visual Studio Elevation of Privilege Vulnerability

Summary

An elevation of privilege vulnerability exists in Git for Visual Studio when it improperly parses configuration files. An attacker who successfully exploited the vulnerability could execute code in the context of another local user. To exploit the vulnerability, an authenticated attacker would need to modify Git configuration files on a system prior to a full installation of the application. The attacker would then need to convince another user on the system to execute specific Git commands. The update addresses the issue by changing the permissions required to edit configuration files.

Severity

No CVSS data available.
