CVE-2021-33360Public exploitNetwork attack vector

Arbitrary code execution via unsanitized output filename

Published Mar 10, 2023 · Updated Feb 28, 2025

Command injection in Stoqey gnuplot 0.0.3 and earlier allows attackers to execute arbitrary code via a crafted output filename. The plotCallack function interpolates options.filename into touch and gnuplot shell commands passed to child_process.exec without neutralization. Exploitation requires an application to pass attacker-controlled data into the filename option, after which commands run with the application's privileges.
