Technical details
The vulnerability is a command injection flaw (CWE-94, CWE-184) in netrw's menu construction code. Functions s:NetrwBookmarkMenu(), s:NetrwTgtMenu(), and related code build :menu commands by concatenating user-controlled directory paths without properly escaping the pipe character (|) which terminates Ex commands, and in some cases without escaping single quotes embedded in strings. An attacker can craft a directory path containing | or ' characters to inject arbitrary Ex commands and, via :!, arbitrary OS commands. Attack requires GUI Vim with menus enabled (defaults) and the victim browsing or bookmarking an attacker-controlled path. The issue is fixed in version 9.2.0840.
