Security readout for executives and security teams
Plain-English summary
This CVE describes a denial-of-service issue in OpenDaylight’s l2switch OpenFlow communication component. If an affected controller is still in use, switch-controller communication could be disrupted. The provided sources do not include CVSS, a named patch, or evidence of active exploitation.
Executive priority
Treat as a legacy SDN control-plane risk. Prioritize if OpenDaylight controls business-critical network paths; otherwise handle through legacy platform retirement and vendor-supported upgrade planning.
Technical view
CVE-2017-1000357 affects OpenDaylight odl-l2switch-switch, the feature responsible for OpenFlow communication. Listed affected versions are 3.3 Lithium-SR3, 3.4 Lithium-SR4, 4.0 Beryllium, 4.1 Beryllium-SR1, 4.2 Beryllium-SR2, and 4.4 Beryllium-SR4.
Likely exposure
Exposure is likely limited to environments still running the listed legacy OpenDaylight versions with the odl-l2switch-switch feature in use for OpenFlow switch management.
Exploitation context
The source bundle describes a denial-of-service condition when a switch rejects packets from the controller. It does not cite public exploitation, CISA KEV listing, exploit maturity, or attacker prerequisites.
Researcher notes
Evidence is sparse. The CVE record names the component, affected versions, and DoS impact, but does not provide CVSS, CWE, patch details, or confirmed exploitation. Avoid assuming broader OpenDaylight components are affected.
Mitigation direction
- Inventory OpenDaylight deployments and identify listed Lithium or Beryllium versions.
- Check OpenDaylight or vendor guidance for fixed releases or supported upgrade paths.
- Restrict controller-switch management-plane access to trusted network segments.
- Disable or replace the affected l2switch feature if it is unnecessary.
- Monitor controller availability and OpenFlow communication failure patterns.
Validation and detection
- Confirm whether OpenDaylight is deployed in production or lab control-plane networks.
- Verify the exact OpenDaylight version against the affected version list.
- Determine whether odl-l2switch-switch is installed and actively used.
- Review controller logs for switch packet rejection or OpenFlow communication failures.
- Document compensating controls around switch-to-controller connectivity.
