CyberRota Analysis
AI-GeneratedA critical path traversal vulnerability in the NTP configuration module of OPNsense allows attackers to overwrite arbitrary files on the system with root privileges by manipulating specific parameters. This poses a significant risk to the integrity and security of the affected systems, particularly for organizations relying on OPNsense for firewall and routing functions. Users of versions prior to 26.1.9 of opnsense/core and 26.4_20 of BE/opnsense/core should prioritize immediate updates to mitigate this vulnerability.

Original NVD Description
OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.9 of opnsense/core and version 26.4_20 of BE/opnsense/core, a path traversal vulnerability in the NTP configuration module allows an attacker to overwrite arbitrary files on the system as the root user. By manipulating the GPS or PPS serial port parameter, an attacker with access to the NTP configuration can escape the intended directory and force the system to write user-controlled data to any file on the filesystem. Version 26.1.9 of opnsense/core and version 26.4_20 of BE/opnsense/core patch the issue.
