It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-6679 in the wild and no public exploit code.\n\nAffected product: Cisco Umbrella Virtual Appliance Version 2.0.3 and prior. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2017-6679/ (Markdown: https://insights.sbomify.com/CVE-2017-6679/index.md)","id":"CVE-2017-6679","markdown":"https://insights.sbomify.com/CVE-2017-6679/index.md","name":"CVE-2017-6679","record":{"aliases":["GHSA-x42g-fj2g-26mm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Umbrella Virtual Appliance","requires_auth":"high_privilege","summary":"An undocumented auto-initiated SSH tunnel allowed Cisco personnel to access the appliance without explicit customer approval, bypassing security controls.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"umbrella_virtual_appliance","vendor":"cisco"}],"cvss":{"score":6.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The Cisco Umbrella Virtual Appliance Version 2.0.3 and prior contained an undocumented encrypted remote support tunnel (SSH) which auto initiated from the customer's appliance to Cisco's SSH Hubs in the Umbrella datacenters.
