Fix not verifiedRockwell 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.

The product reads data past the end, or before the beginning, of the intended buffer.
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-125: Out-of-bounds Read. The product reads data past the end, or before the beginning, of the intended buffer.
