1756 En4Tr Firmware
Monthly
A security issue exists in the protected mode of EN4TR devices, where sending specifically crafted messages during a Forward Close operation can cause the device to crash. Rated high severity (CVSS 7.1), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
A security issue exists in the protected mode of 1756-EN4TR and 1756-EN2TR communication modules, where a Concurrent Forward Close operation can trigger a Major Non-Recoverable (MNFR) fault. Rated high severity (CVSS 7.1), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Due to a memory leak, a denial-of-service vulnerability exists in the Rockwell Automation affected products. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
A specific malformed fragmented packet type (fragmented packets may be generated automatically by devices that send large amounts of data) can cause a major nonrecoverable fault (MNRF) Rockwell. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Where this vulnerability exists in the Rockwell Automation 1756-EN4* Ethernet/IP communication products, it could allow a malicious user to cause a denial of service by asserting the target system. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
