EPSS · scored 2026-10-23

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.

Vendor and ecosystem advisories describing this.

  • SCA-2026-0006Vulnerabilities affecting SICK Lector85x and SICK Lector83x2026-03-06csaf · sick_psirtDE

    Two vulnerabilities affecting the SICK Lector85x and SICK Lector83x product families have been identified. Both vulnerabilities are caused by insufficient access restrictions in HTTP-based interfaces, which may allow unauthenticated access to sensitive device resources. Depending on the configuration, this could lead to unauthorized modification of device settings and security-relevant data. SICK recommends applying the defined remediations for both vulnerabilities. SICK is currently not aware of any public exploits.
