It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-1618 in the wild and no public exploit code.\n\nAffected product: Juniper Junos. 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-2020-1618/ (Markdown: https://insights.sbomify.com/CVE-2020-1618/index.md)","id":"CVE-2020-1618","markdown":"https://insights.sbomify.com/CVE-2020-1618/index.md","name":"CVE-2020-1618","record":{"aliases":["GHSA-2r53-mrx4-q6h9"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Juniper network switch","requires_auth":"none","summary":"An attacker with physical console access can bypass authentication to gain root privileges on Juniper EX and QFX switches under specific reboot conditions.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"On Juniper Networks EX and QFX Series, an authentication bypass vulnerability may allow a user connected to the console port to login as root without any password.
