CVE-2024-29021Public exploitNetwork attack vector

Host takeover via SSRF-assisted command injection

Published Apr 18, 2024 · Updated Aug 2, 2024

Server-side request forgery in Judge0 1.13.0 and earlier allows remote attackers to execute code as root on the Linux host. The enable_network option lets submitted code reach PostgreSQL; a default or brute-forceable database password permits column-type changes that inject values into the shell-built isolate command. The chain requires network access to be allowed and a weak database password, then escapes the privileged worker container and grants full host control.
