CVE-2026-119560: OPNsense core configuration injection in NTP GPS/PPS fudge

CVE-2026-119560 · Severity: medium · CVSS 5.9 · Published 2026-10-30

OPNsense is an open-source firewall and router that manages system services through a web interface. A configuration injection vulnerability in the NTP GPS/PPS settings allows authenticated users with specific privileges to inject arbitrary directives into the NTP daemon configuration file, potentially giving attackers the ability to manipulate time synchronization or execute commands with root privileges. An attacker would need an existing GPS or PPS device connected to the system and the page-services-ntp-gps or page-services-ntp-pps privilege to exploit this.

Technical details

The vulnerability is a newline injection flaw in the fudge1, fudge2, and refid input fields of the GPS/PPS NTP configuration pages (services_ntpd_gps.php and services_ntpd_pps.php). Unlike earlier fixes that strip CR/LF from timeserver host inputs, these GPS/PPS fudge fields do not sanitize embedded newlines, allowing authenticated users to inject arbitrary directives into /var/etc/ntpd.conf. Since ntpd runs as root without a -u flag for privilege separation, injected directives execute with root privileges; attackers can abuse this to manipulate configuration, create files, or potentially achieve code execution through ntpd's configuration capabilities.
