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-2023-44195 in the wild and no public exploit code.\n\nAffected product: Juniper Junos Os Evolved. 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-2023-44195/ (Markdown: https://insights.sbomify.com/CVE-2023-44195/index.md)","id":"CVE-2023-44195","markdown":"https://insights.sbomify.com/CVE-2023-44195/index.md","name":"CVE-2023-44195","record":{"aliases":["GHSA-f7rx-678f-vf6q"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Junos OS Evolved","requires_auth":"none","summary":"An unauthenticated attacker can bypass firewall filters to send packets to the Routing Engine, causing resource exhaustion and potential unauthorized access.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos_os_evolved","vendor":"juniper"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-923","name":"Improper Restriction of Communication Channel to Intended Endpoints"}],"description":"An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the NetworkStack agent daemon (nsagentd) of Juniper Networks Junos OS Evolved allows an unauthenticated network based attacker to cause limited impact to the availability of the system.\n\nIf specific packets reach the Routing-Engine (RE) these will be processed normally even if firewall filters are in place which should have prevented this.
