Rockwell Automation 1734 POINT I/O
A denial-of-service vulnerability exists in Rockwell Automation 1734 POINT I/O version 3.023 that allows remote attackers to craft malicious CIP (Common Industrial Protocol) messages causing the module to fault and require restart. The issue stems from improper resource allocation without throttling limits and carries a CVSS score of 7.5. Rockwell Automation recommends migration to version 5034-OB8 for affected users.
Why it matters: Organizations operating Rockwell Automation 1734 POINT I/O modules in critical manufacturing environments face potential production disruptions if attackers trigger denial-of-service conditions on these industrial control devices; upgrade or network segmentation steps should be prioritized.
