CVE-2018-17924 1 Rockwellautomation 32 1756-en2f Series A, 1756-en2f Series A Firmware, 1756-en2f Series B and 29 more 2022-05-02 7.8 HIGH 8.6 HIGH
Rockwell Automation MicroLogix 1400 Controllers and 1756 ControlLogix Communications Modules An unauthenticated, remote threat actor could send a CIP connection request to an affected device, and upon successful connection, send a new IP configuration to the affected device even if the controller in the system is set to Hard RUN mode. When the affected device accepts this new IP configuration, a loss of communication occurs between the device and the rest of the system as the system traffic is still attempting to communicate with the device via the overwritten IP address.
CVE-2021-32926 1 Rockwellautomation 4 Micro800, Micro800 Firmware, Micrologix 1400 and 1 more 2021-06-15 5.0 MEDIUM 7.5 HIGH
When an authenticated password change request takes place, this vulnerability could allow the attacker to intercept the message that includes the legitimate, new password hash and replace it with an illegitimate hash. The user would no longer be able to authenticate to the controller (Micro800: All versions, MicroLogix 1400: Version 21 and later) causing a denial-of-service condition
CVE-2021-22659 1 Rockwellautomation 2 Micrologix 1400, Micrologix 1400 Firmware 2021-03-31 7.5 HIGH 8.6 HIGH
Rockwell Automation MicroLogix 1400 Version 21.6 and below may allow a remote unauthenticated attacker to send a specially crafted Modbus packet allowing the attacker to retrieve or modify random values in the register. If successfully exploited, this may lead to a buffer overflow resulting in a denial-of-service condition. The FAULT LED will flash RED and communications may be lost. Recovery from denial-of-service condition requires the fault to be cleared by the user.
CVE-2020-6984 1 Rockwellautomation 6 Micrologix 1100, Micrologix 1100 Firmware, Micrologix 1400 and 3 more 2020-03-20 5.0 MEDIUM 7.5 HIGH
Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior, The cryptographic function utilized to protect the password in MicroLogix is discoverable.
CVE-2020-6988 1 Rockwellautomation 6 Micrologix 1100, Micrologix 1100 Firmware, Micrologix 1400 and 3 more 2020-03-20 5.0 MEDIUM 7.5 HIGH
Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior, A remote, unauthenticated attacker can send a request from the RSLogix 500 software to the victim’s MicroLogix controller. The controller will then respond to the client with used password values to authenticate the user on the client-side. This method of authentication may allow an attacker to bypass authentication altogether, disclose sensitive information, or leak credentials.
CVE-2017-12093 1 Rockwellautomation 2 Micrologix 1400, Micrologix 1400 B Firmware 2019-10-03 5.0 MEDIUM 7.5 HIGH
An exploitable insufficient resource pool vulnerability exists in the session communication functionality of Allen Bradley Micrologix 1400 Series B Firmware 21.2 and before. A specially crafted stream of packets can cause a flood of the session resource pool resulting in legitimate connections to the PLC being disconnected. An attacker can send unauthenticated packets to trigger this vulnerability.
CVE-2017-12089 1 Rockwellautomation 2 Micrologix 1400, Micrologix 1400 B Firmware 2019-10-03 7.8 HIGH 7.5 HIGH
An exploitable denial of service vulnerability exists in the program download functionality of Allen Bradley Micrologix 1400 Series B FRN 21.2 and before. A specially crafted packet can cause a device fault resulting in halted operations. An attacker can send an unauthenticated packet to trigger this vulnerability.
CVE-2017-12092 1 Rockwellautomation 2 Micrologix 1400, Micrologix 1400 B Firmware 2018-08-01 5.0 MEDIUM 7.5 HIGH
An exploitable file write vulnerability exists in the memory module functionality of Allen Bradley Micrologix 1400 Series B FRN 21.2 and before. A specially crafted packet can cause a file write resulting in a new program being written to the memory module. An attacker can send an unauthenticated packet to trigger this vulnerability.
CVE-2017-12088 1 Rockwellautomation 2 Micrologix 1400, Micrologix 1400 B Firmware 2018-05-18 7.8 HIGH 7.5 HIGH
An exploitable denial of service vulnerability exists in the Ethernet functionality of the Allen Bradley Micrologix 1400 Series B FRN 21.2 and below. A specially crafted packet can cause a device power cycle resulting in a fault state and deletion of ladder logic. An attacker can send one unauthenticated packet to trigger this vulnerability
CVE-2017-12090 1 Rockwellautomation 2 Micrologix 1400, Micrologix 1400 B Firmware 2018-05-15 7.8 HIGH 7.5 HIGH
An exploitable denial of service vulnerability exists in the processing of snmp-set commands of the Allen Bradley Micrologix 1400 Series B FRN 21.2 and below. A specially crafted snmp-set request, when sent without associated firmware flashing snmp-set commands, can cause a device power cycle resulting in downtime for the device. An attacker can send one packet to trigger this vulnerability.
