Assigner: MITRE

Description
OPNsense before 25.1.8 contains an authenticated command injection vulnerability in its Bridge Interface Edit endpoint (interfaces_bridge_edit.php). The span POST parameter is concatenated into a system-level command without proper sanitization or escaping, allowing an administrator to inject arbitrary shell operators and payloads. Successful exploitation results in remote code execution with the privileges of the web service (typically root), potentially leading to full system compromise or lateral movement. This vulnerability arises from inadequate input validation and improper handling of user-supplied data in backend command invocations.

Executive Summary

This vulnerability is an authenticated command injection in OPNsense 25.1's Bridge Interface Edit endpoint. It occurs because the 'span' POST parameter is directly included in a system-level command without proper sanitization or escaping. This allows an administrator to inject arbitrary shell commands, leading to remote code execution with the privileges of the web service, typically root.

Impact Analysis

Exploitation of this vulnerability can lead to remote code execution with root privileges, potentially resulting in full system compromise or lateral movement within the network. This means an attacker could take complete control over the affected system and possibly use it to attack other systems.
