Vulnerability Details : CVE-2013-2806
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.

CWE ids for CVE-2013-2806
-
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 occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.Assigned by:
