Command Injection in ascii-art
GHSA-9hqj-38j2-5jgm
- Affected
- npm ascii-art <= 1.4.2
- Fixed in
- 1.4.4· Vendor fix available
- Issue
- Versions of ascii-art before 1.4.4 are vulnerable to command injection. This is exploitable when user input is passed into the argument of the ascii-art preview command. Example Proof of concept: ascii-art preview 'doom"; touch /tmp/malicious; echo "' Given that the input is passed on the command line and none of the api methods are vulnerable to this, the likely exploitation vector is when the ascii-art comment is being called programmatically using something like execFile. Recommendation Update to version 1.4.4 or later.
Recommended action: Upgrade to 1.4.4 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
