Description (CNA)
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.
