Assigner: GitHub, Inc.

Description

Vim is an open source, command line text editor. Prior to version 9.2.0202, a command injection vulnerability exists in Vim's glob() function on Unix-like systems. By including a newline character (\n) in a pattern passed to glob(), an attacker may be able to execute arbitrary shell commands. This vulnerability depends on the user's 'shell' setting. This issue has been patched in version 9.2.0202.

Attack-Flow Graph

Executive Summary

This vulnerability exists in the glob() function of the Vim text editor on Unix-like systems prior to version 9.2.0202. An attacker can include a newline character (\n) in a pattern passed to the glob() function, which may allow them to execute arbitrary shell commands. The exploitability depends on the user's 'shell' setting.

Impact Analysis

If exploited, this vulnerability can allow an attacker to execute arbitrary shell commands with the privileges of the user running Vim. This could lead to unauthorized actions such as modifying files, stealing data, or further compromising the system.
