CVE-2020-7604Public exploitNetwork attack vector

Arbitrary command execution via unsanitized image filename

Published Mar 15, 2020 · Updated Aug 4, 2024

OS command injection in Benjamin Truyman Pulverizr 0.7.0 and earlier allows attackers to execute arbitrary commands via crafted image filenames. In lib/job.js, Job.prototype.compress concatenates an attacker-controlled filename into a shell cp command passed to child_process.exec without neutralizing shell metacharacters. Exploitation requires the attacker to create a specially named supported image file and cause Pulverizr to process it; commands run with the Pulverizr process's privileges.
