CVE-2026-2330
Received Received - Intake
Unauthorized Filesystem Access via CROWN REST Interface Whitelist Bypass

Publication date: 2026-03-06

Last updated on: 2026-03-06

Assigner: SICK AG

Description
An attacker may access restricted filesystem areas on the device via the CROWN REST interface due to incomplete whitelist enforcement. Certain directories intended for internal testing were not covered by the whitelist and are accessible without authentication. An unauthenticated attacker could place a manipulated parameter file that becomes active after a reboot, allowing modification of critical device settings, including network configuration and application parameters.

Executive Summary

This vulnerability allows an attacker to access restricted filesystem areas on a device through the CROWN REST interface because the whitelist enforcement is incomplete.

Some directories meant only for internal testing are not included in the whitelist and can be accessed without any authentication.

An unauthenticated attacker can place a manipulated parameter file in these accessible directories, which becomes active after the device reboots.

This manipulated file can modify critical device settings such as network configuration and application parameters.

Impact Analysis

The vulnerability can have severe impacts including unauthorized modification of critical device settings.

An attacker could change network configurations and application parameters, potentially disrupting device operation or enabling further attacks.

Since the attacker does not need authentication, this increases the risk of exploitation and compromise of the device.
