Detailsinfo

A vulnerability classified as problematic has been found in OPNsense core up to 26.7.8. Affected is some unknown processing of the file ntpd.inc of the component NTP Daemon. The manipulation of the argument fudge/refid with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on integrity, and availability. CVE summarizes:

OPNsense core through 26.7.8 contains a configuration injection vulnerability that allows authenticated users to append ntpd.conf directives by embedding newlines in the fudge and refid fields. Attackers holding the page-services-ntp-gps or PPS privilege can submit CR/LF characters via services_ntpd_gps.php or services_ntpd_pps.php to inject directives loaded by ntpd running as root.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-119560 since 10/30/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
