CVE-2020-36642Network attack vector

Root privilege escalation via unescaped cputime parameter

Published Jan 6, 2023 · Updated Apr 10, 2025

Command injection in trampgeek Jobe 1.6 and earlier allows remote attackers to execute commands via a crafted cputime run parameter. LanguageTask.php's run_in_sandbox path places the unchecked nonnumeric value directly into a sandbox command executed as www-data. On installations reachable without API keys, www-data command execution enables modification of runguard for root execution.
