Command Injection in ascii-art

  • Disclosed: 01.09.2020
  • Updated: 11.10.2026 10:22

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.
