An attacker could send a crafted HTTP/HTTPS request to render the web server unavailable and/or lead to remote code execution caused by a stack-based buffer overflow vulnerability. A cold restart is required for recovering
CompactLogix 5370 L1, L2, and L3 Controllers, Compact GuardLogix 5370 controllers, and Armor Compact GuardLogix 5370 Controllers Versions 20 - 30 and earlier.
An attacker could send crafted SMTP packets to cause a denial-of-service condition where the controller enters a major non-recoverable faulted state (MNRF) in CompactLogix 5370 L1, L2, and L3 Controllers, Compact GuardLogix 5370 controllers, and Armor Compact GuardLogix 5370 Controllers Versions 20 - 30 and earlier.
In Rockwell Automation MicroLogix 1400 Controllers Series A, All Versions Series B, v15.002 and earlier, MicroLogix 1100 Controllers v14.00 and earlier, CompactLogix 5370 L1 controllers v30.014 and earlier, CompactLogix 5370 L2 controllers v30.014 and earlier, CompactLogix 5370 L3 controllers (includes CompactLogix GuardLogix controllers) v30.014 and earlier, an open redirect vulnerability could allow a remote unauthenticated attacker to input a malicious link to redirect users to a malicious site that could run or download arbitrary malware on the user’s machine.
Rockwell Automation PowerFlex 525 AC Drives 5.001 and earlier allow remote attackers to cause a denial of service by crashing the Common Industrial Protocol (CIP) network stack. The vulnerability allows the attacker to crash the CIP in a way that it does not accept new connections, but keeps the current connections active, which can prevent legitimate users from recovering control.
A vulnerability was found in Rockwell Automation RSLinx Classic versions 4.10.00 and prior. An input validation issue in a .dll file of RSLinx Classic where the data in a Forward Open service request is passed to a fixed size buffer, allowing an attacker to exploit a stack-based buffer overflow condition.
Rockwell Automation EtherNet/IP Web Server Modules 1756-EWEB (includes 1756-EWEBK) Version 5.001 and earlier, and CompactLogix 1768-EWEB Version 2.005 and earlier. A remote attacker could send a crafted UDP packet to the SNMP service causing a denial-of-service condition to occur until the affected product is restarted.
The potential exists for exposure of the product's password used to restrict unauthorized access to Rockwell PLC5/SLC5/0x/RSLogix 1785-Lx and 1747-L5x controllers. The potential exists for an unauthorized programming and configuration client to gain access to the product and allow changes to the product’s configuration or program. When applicable, upgrade product firmware to a version that includes enhanced security functionality compatible with Rockwell Automation's FactoryTalk Security services.
Rockwell Automation RSLinx Enterprise Software (LogReceiver.exe) CPR9, CPR9-SR1, CPR9-SR2, CPR9-SR3, CPR9-SR4, CPR9-SR5, CPR9-SR5.1, and CPR9-SR6 does not handle input correctly and results in a logic error if it receives a datagram with an incorrect value in the “Record Data Size” field. By sending a datagram to the service over Port 4444/UDP with the “Record Data Size” field modified to an oversized value, an attacker could cause an out-of-bounds read access violation that leads to a service crash. The service can be recovered with a manual reboot.

Rockwell Automation RSLinx Enterprise Software (LogReceiver.exe) CPR9, CPR9-SR1, CPR9-SR2, CPR9-SR3, CPR9-SR4, CPR9-SR5, CPR9-SR5.1, and CPR9-SR6 does not handle input correctly and results in a logic error if it calculates an incorrect value for the “End of Current Record” field. By sending a datagram to the service over Port 4444/UDP with the “Record Data Size” field modified to a specifically oversized value, the service will calculate an undersized value for the “Total Record Size.” Then the service will calculate an incorrect value for the “End of Current Record” field causing access violations that lead to a service crash. The service can be recovered with a manual reboot.
