Candidate: CVE-2021-42740 PublicDate: 2021-10-21 15:15:00 UTC References: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-42740 https://github.com/substack/node-shell-quote/commit/5799416ed454aa4ec9afafc895b4e31760ea1abe https://www.npmjs.com/package/shell-quote https://github.com/substack/node-shell-quote/blob/master/CHANGELOG.md#173 Description: The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is {A-z] instead of the correct {A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.
