CVE-2019-1010252: The Linux Foundation ONOS 2.0.0 and earlier is affected by: Poor Input-validation.

The Linux Foundation ONOS 2.0.0 and earlier is affected by: Poor Input-validation. The impact is: A network administrator (or attacker) can install unintended flow rules in the switch by mistake. The component is: applyFlowRules() and apply() functions in FlowRuleManager.java. The attack vector is: network management and connectivity.

Security readout for executives and security teams

Plain-English summary

ONOS 2.0.0 and earlier may accept insufficiently validated flow-rule input, allowing unintended rules to be installed on switches. For the business, the concern is network behavior being changed incorrectly through the SDN controller. Public data does not provide severity scoring, a fixed version, or proof of active exploitation.

Executive priority

Treat as a targeted network-control risk if ONOS is present in production. Priority depends on whether ONOS 2.0.0 or earlier is deployed and who can submit flow rules. Absence of severity and exploit evidence lowers confidence, not necessarily operational impact.

Technical view

The CVE cites poor input validation in FlowRuleManager.java, specifically applyFlowRules() and apply(). The stated impact is installation of unintended switch flow rules through network management and connectivity paths. The source bundle does not include CVSS, CWE mapping, authentication details, exploit maturity, or remediation details.

Likely exposure

Exposure appears limited to environments running The Linux Foundation ONOS 2.0.0 or earlier, especially where ONOS manages production switch flow rules. The sources do not define default exposure, required privileges, reachable interfaces, or affected deployments beyond ONOS version scope.

Exploitation context

No cited source states active exploitation, and the CVE is not marked KEV. The described vector is network management and connectivity, meaning abuse or mistakes would likely involve access to ONOS management workflows or integrations that submit flow rules.

Researcher notes

The public record is sparse. It names affected functions and impact but omits root-cause detail, patch status, proof-of-concept status, and exploit prerequisites. Do not infer remote unauthenticated exploitation from the available sources.

Mitigation direction

  • Inventory ONOS deployments and identify versions 2.0.0 or earlier.
  • Check ONOS or Linux Foundation guidance for fixed versions or workarounds.
  • Restrict ONOS management access to trusted administrators and automation.
  • Review recent flow-rule changes for unintended or unauthorized entries.
  • Apply change control to SDN rule deployments until remediation is confirmed.

Validation and detection

  • Confirm ONOS version on each controller managing switches.
  • Review whether applyFlowRules() or related APIs are reachable by untrusted users.
  • Audit switch flow tables for unexpected rules created through ONOS.
  • Check controller logs for unusual flow-rule submissions or failures.
  • Verify management interfaces are segmented and access-controlled.
