By sending malformed common industrial protocol (CIP) packet, an attacker may be able to overflow a stack-based buffer and execute code on the controller or initiate a nonrecoverable fault resulting in a denial of service.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 10.5%, higher than 95% of all known CVEs. Patch or mitigate before the next change window.
