Detailsinfo

A vulnerability, which was classified as problematic, was found in Rockwell Automation RSLinx Enterprise up to CPR9-SR6 (Automation Software). Affected is an unknown functionality of the file LogReceiver.exe of the component Service Port 4444. The manipulation as part of a Datagram leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on availability. CVE summarizes:

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.
