CVE-2026-9636 1 Rockwellautomation 5 1756-en4tr, Compact Guardlogix 5380, Compactlogix 5380 and 2 more 2026-11-11 N/A
A security issue exists within CompactLogix® 5380, ControlLogix® 5580, and EN4 communication modules related to CIP Security certificate revocation handling. The security issue stems from the controller failing to properly reject certificates signed by an intermediate certificate that has been revoked via a Certificate Revocation List (CRL). This could allow a network-based attacker to establish a connection using a certificate that should be untrusted, potentially bypassing CIP Security protections.
CVE-2025-8007 1 Rockwellautomation 11 1756-en2tr Series A, 1756-en2tr Series A Firmware, 1756-en2tr Series B and 8 more 2025-09-17 6.5 Medium
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. This condition may lead to unexpected system crashes and loss of device availability.
CVE-2025-8008 1 Rockwellautomation 11 1756-en2tr Series A, 1756-en2tr Series A Firmware, 1756-en2tr Series B and 8 more 2025-09-17 6.5 Medium
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.
CVE-2024-5659 1 Rockwellautomation 12 1756-en4, 1756-en4 Firmware, Compact Guardlogix 5380 and 9 more 2024-11-21 6.5 Medium
Rockwell Automation was made aware of a vulnerability that causes all affected controllers on the same network to result in a major nonrecoverable fault(MNRF/Assert). This vulnerability could be exploited by sending abnormal packets to the mDNS port. If exploited, the availability of the device would be compromised.
CVE-2024-3493 1 Rockwellautomation 16 1756-en4tr, 1756-en4tr Firmware, Compact Guardlogix 5380 and 13 more 2024-11-21 8.6 High
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 Automation's ControlLogix 5580, Guard Logix 5580, CompactLogix 5380, and 1756-EN4TR. If exploited, the affected product will become unavailable and require a manual restart to recover it. Additionally, an MNRF could result in a loss of view and/or control of connected devices.
CVE-2023-3596 1 Rockwellautomation 6 1756-en4tr, 1756-en4tr Firmware, 1756-en4trk and 3 more 2024-11-21 7.5 High
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 through maliciously crafted CIP messages.
CVE-2024-8626 1 Rockwellautomation 12 1756-en4tr, 1756-en4tr Firmware, Compact Guardlogix 5380 and 9 more 2024-10-10 7.5 High
Due to a memory leak, a denial-of-service vulnerability exists in the Rockwell Automation affected products. A malicious actor could exploit this vulnerability by performing multiple actions on certain web pages of the product causing the affected products to become fully unavailable and require a power cycle to recover.
CVE-2024-6077 1 Rockwellautomation 18 1756-en4, 1756-en4 Firmware, Compact Guardlogix 5380 Sil2 Firmware and 15 more 2024-09-19 7.5 High
A denial-of-service vulnerability exists in the Rockwell Automation affected products when specially crafted packets are sent to the CIP Security Object. If exploited the device will become unavailable and require a factory reset to recover.
