Security readout for executives and security teams
Plain-English summary
ONOS 1.15.0 has a reported flaw in its YANG web resource that mishandles backquote characters in strings used by a shell command. That pattern can be dangerous because crafted input may affect command execution. The source bundle does not provide CVSS, exploit requirements, or a confirmed patch status.
Executive priority
Prioritize assessment if ONOS manages production network infrastructure. Business urgency depends on whether ONOS 1.15.0 and the YANG web component are exposed to untrusted or broad internal users.
Technical view
CVE-2019-13624 identifies apps/yang/web/src/main/java/org/onosproject/yang/web/YangWebResource.java in ONOS 1.15.0 as mishandling backquotes inside strings later used in a shell command. The bundle does not document authentication needs, reachable endpoints, impact boundaries, or affected versions beyond ONOS 1.15.0.
Likely exposure
Exposure appears limited to environments running ONOS 1.15.0 with the YANG web functionality present and reachable. The supplied affected-product metadata is incomplete, so confirm exposure from deployed versions and enabled ONOS applications rather than relying on CPE data.
Exploitation context
The bundle does not cite CISA KEV listing or active exploitation. It indicates a shell-command string handling issue, but does not provide exploit prerequisites, proof of exploitation, or real-world abuse evidence.
Researcher notes
Evidence is sparse: no CVSS, CWE, detailed advisory, or affected-version range is included. Treat the shell-command context as potentially serious, but avoid assuming remote unauthenticated exploitation without confirming the endpoint, permissions, and vendor patch details.
Mitigation direction
- Inventory ONOS deployments and identify any running version 1.15.0.
- Review the referenced ONOS Gerrit change and vendor guidance for the intended fix.
- Restrict access to ONOS web and YANG management interfaces to trusted administrators.
- Upgrade or patch ONOS if vendor-maintained guidance confirms a fixed release.
- Monitor ONOS logs for unusual YANG web requests or command-related errors.
Validation and detection
- Confirm whether ONOS 1.15.0 is deployed in production or lab networks.
- Check whether the YANG app and YangWebResource path exist in the deployed build.
- Verify whether the referenced Gerrit change is present in source or packaged artifacts.
- Review access controls around ONOS management, web, and API surfaces.
- Document any compensating controls if immediate upgrade is unavailable.
