Summary
SICK FlexiCompact affected by Denial of Service vulnerability

Notes

SICK discovered a vulnerability in the configuration interface of FlexiCompact that can be accessed via Ethernet or USB. If exploited, this potentially allows a remote unauthenticated attacker to impact availabiltiy of the FlexiCompact. SICK recommends making sure to run a non-affected version. SICK is not aware of an exploit targeting this vulnerability.
General Security Measures
As general security measures, SICK recommends to minimize network exposure of the devices, restrict network access and follow recommended security practices in order to run the devices in a protected IT environment.
Vulnerability Classification
SICK performs vulnerability classification by using the CVSS scoring system (*CVSS v3.1*). The environmental score is dependent on the customer’s environment and can affect the overall CVSS score. SICK recommends that customers individually evaluate the environmental score to achieve final scoring.
