Security readout for executives and security teams
Plain-English summary
This vulnerability can let an unauthenticated network sender crash Rockwell Automation RSLinx Enterprise LogReceiver in affected CPR9 releases. In an industrial environment, that is primarily an availability risk: logging or related software services may stop until manually rebooted.
Executive priority
Treat this as a targeted operational resilience issue, not confirmed active exploitation. Prioritize remediation where affected RSLinx systems support production operations or are reachable beyond a tightly controlled ICS segment.
Technical view
CVE-2013-2806 is an input-handling logic error associated with CWE-190. Malformed UDP traffic to the LogReceiver service can cause incorrect record-size calculations, access violations, and a service crash. The source bundle names CPR9 through CPR9-SR6 as affected.
Likely exposure
Exposure is likely limited to organizations still running the listed legacy RSLinx Enterprise CPR9 versions, especially where LogReceiver is reachable over UDP port 4444 from untrusted or broadly routed networks.
Exploitation context
The bundle does not indicate CISA KEV listing or active exploitation. It describes a remote network-triggered crash condition, but provides no public evidence of exploitation in the supplied sources.
Researcher notes
The public details support denial of service, not code execution. Patch details are referenced through a Rockwell advisory requiring login, so fix specificity is limited in the supplied bundle.
Mitigation direction
- Check Rockwell Automation advisory 537599 for applicable patches and supported upgrade paths.
- Apply vendor patches or upgrade affected CPR9 deployments where guidance confirms applicability.
- Restrict UDP port 4444 access to trusted ICS management hosts only.
- Segment RSLinx Enterprise systems away from enterprise and internet-reachable networks.
- Prepare operational recovery steps for service crash and manual reboot scenarios.
Validation and detection
- Inventory RSLinx Enterprise versions and identify any CPR9 through CPR9-SR6 installations.
- Confirm whether LogReceiver is enabled on affected hosts.
- Review firewall rules for UDP port 4444 reachability.
- Check system and application logs for LogReceiver crashes or access violations.
- Verify applied patches or upgraded versions against Rockwell guidance.
