Summary
Improper handling of exceptional conditions in the platform mechanism AutoIP can lead to a reboot of the device, if parsing malformed network packets. This can lead to a temporary impact of the availability of the device. The AutoIP mechanism is used by the SOPAS Engineering Tool (SOPAS-ET), e.g. to detect SICK devices in the network and change their IP configuration. This is intended to simplify the initial setup and the maintenance of the devices. The devices listen on port 30718 for UDP broadcasts. SICK has released a new firmware version for the MSC800, Bulkscan LMS111, Bulkscan LMS511 and other LMS1xx devices.
Remediation
Update to version V1.04 SICK removed the AutoIP weakness with the same available fix for the MSC800. The update can only be implemented by a SICK service technician, either by remote access or on site. To obtain the update, please contact your local service technician.

01

What, why and how

Platform mechanism AutoIP allows remote attackers to reboot the device via a crafted packet in SICK AG solutions Bulkscan LMS111, Bulkscan LMS511, CLV62x – CLV65x, ICR890-3, LMS10x, LMS11x, LMS15x, LMS12x, LMS13x, LMS14x, LMS5xx, LMS53x, MSC800, RFH.

What

Platform mechanism AutoIP allows remote attackers to reboot the device via a crafted packet in SICK AG solutions Bulkscan LMS111, Bulkscan LMS511, CLV62x – CLV65x, ICR890-3, LMS10x, LMS11x, LMS15x, LMS12x, LMS13x, LMS14x, LMS5xx, LMS53x, MSC800, RFH.

Why

The product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

CWE-703: Improper Check or Handling of Exceptional Conditions. The product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product.
