CVE-2023-30261Public exploitNetwork attack vector

Unauthenticated root command execution via callback parameters

Published Jun 26, 2023 · Updated Dec 3, 2024

OS command injection in openWB 1.6 and 1.7 allows remote attackers to execute arbitrary host commands via crafted GET requests. The callback_lp.php, callback_lp1.php, and callback_lp2.php endpoints pass unsanitized request input to system(), allowing shell metacharacters to alter the command. No authentication is required, and the default www-data account has unconstrained sudo access, so successful exploitation executes commands as root.
