Attack profile from CVSS 3.1 · CNA. Fix status from CNA. Impact type from CWE-78.

Summary

Zuke before 1.51.0, including @zuke/core, launches resolved .cmd and .bat shims on Windows through cmd.exe. Because cmd.exe re-parses the command line, it interprets unquoted &, |, or ^ characters in attacker-influenced text as commands (CWE-78). A local attacker who can influence text passed to a tool in node_modules/.bin during a Windows build can run an extra command with the build's credentials, and user interaction is required. POSIX platforms are not affected.

Description from the CNA

Zuke is a code-first, strongly typed build automation system for Deno. Prior to 1.51.0, @zuke/core launches resolved Windows .cmd and .bat shims by prepending cmd /c, causing cmd.exe to reparse a command line assembled with C-runtime quoting rules. A build running on Windows that resolves a tool from node_modules/.bin and passes attacker-influenced text containing an unquoted &, |, or ^ metacharacter can execute an additional attacker-chosen command in the build's context with access to its credentials. POSIX platforms are not affected. This issue is fixed in version 1.51.0.
