An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-0039 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-2019-0039/ (Markdown: https://insights.sbomify.com/CVE-2019-0039/index.md)","id":"CVE-2019-0039","markdown":"https://insights.sbomify.com/CVE-2019-0039/index.md","name":"CVE-2019-0039","record":{"aliases":["GHSA-6q78-gprw-j4gg"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Junos OS","requires_auth":"none","summary":"Attackers can brute-force login credentials via the REST API if enabled, potentially gaining unauthorized access to Junos OS devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"If REST API is enabled, the Junos OS login credentials are vulnerable to brute force attacks.
