Service interruption via enabled ICMP redirection
Published Mar 25, 2025 · Updated Mar 31, 2025
Resource allocation failure in B&R APROL before 4.4-00P5 allows unauthenticated adjacent attackers to interrupt product operation. The operating-system network configuration enables ICMP redirection, but B&R has not disclosed the exact resource exhausted by malicious traffic. Access to an adjacent control network is required, and B&R describes a denial-of-service condition without specifying whether operation hangs, crashes, or reboots.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
