Affected sectors

Risk evaluation

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.

Mitigation summary

Users are strongly recommended to upgrade to release version 2.8.0.
