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-2024-30388 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-2024-30388/ (Markdown: https://insights.sbomify.com/CVE-2024-30388/index.md)","id":"CVE-2024-30388","markdown":"https://insights.sbomify.com/CVE-2024-30388/index.md","name":"CVE-2024-30388","record":{"aliases":["GHSA-fwcw-wmg8-r4vq"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Juniper network switch","requires_auth":"none","summary":"An unauthenticated adjacent attacker can cause a denial of service by sending malformed LACP packets to Juniper QFX5000 and EX Series switches.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-653","name":"Improper Isolation or Compartmentalization"}],"description":"An Improper Isolation or Compartmentalization vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on QFX5000 Series and EX Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).\n\nIf a specific malformed LACP packet is received by a QFX5000 Series, or an EX4400, EX4100 or EX4650 Series device, an LACP flap will occur resulting in traffic loss.\nThis issue affects Junos OS on QFX5000 Series, and on EX4400, EX4100 or EX4650 Series:\n\n  *  20.4 versions from \n\n20.4R3-S4\n\nbefore 20.4R3-S8,\n  *  21.2 versions from \n\n21.2R3-S2\n\nbefore 21.2R3-S6,\n  *  21.4 versions from \n\n21.4R2\n\nbefore 21.4R3-S4,\n\n  *  22.1 versions from\n\n22.1R2\n\n before 22.1R3-S3,\n  *  22.2 versions before 22.2R3-S1,\n  *  22.3 versions before 22.3R2-S2, 22.3R3,\n  *  22.4 versions before 22.4R2-S1, 22.4R3.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Junos OS: QFX5000 Series and EX Series: Specific malformed LACP packets will cause flaps","id":"CVE-2024-30388","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"juniper:junos","products":["juniper:junos"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Junos OS: EX4300 Series: Firewall filter not blocking egress traffic","id":"CVE-2024-30389"},"packages":[],"prev":{"headline":"Junos OS: ACX5448 \u0026 ACX710: Due to interface flaps the PFE process can crash","id":"CVE-2024-30387"},"products":["Junos OS"],"published":"2024-04-12","related":[{"cvss_score":9.8,"headline":"Juniper Junos OS EX Series and SRX Series PHP External Variable Modification","id":"CVE-2023-36845","kev_date_added":"2023-11-13","published":"2023-08-17"},{"cvss_score":8.8,"headline":"Juniper Junos OS Path Traversal","id":"CVE-2020-1631","kev_date_added":"2022-03-25","published":"2020-05-04"},{"cvss_score":6.7,"headline":"Juniper Junos OS Improper Isolation or Compartmentalization","id":"CVE-2025-21590","kev_date_added":"2025-03-13","published":"2025-03-12"},{"cvss_score":5.3,"headline":"Juniper Junos OS SRX Series Missing Authentication for Critical Function","id":"CVE-2023-36851","kev_date_added":"2023-11-13","published":"2023-09-26"},{"cvss_score":5.3,"headline":"Juniper Junos OS EX Series PHP External Variable Modification","id":"CVE-2023-36844","kev_date_added":"2023-11-13","published":"2023-08-17"},{"cvss_score":5.3,"headline":"Juniper Junos OS SRX Series Missing Authentication for Critical Function","id":"CVE-2023-36846","kev_date_added":"2023-11-13","published":"2023-08-17"},{"cvss_score":5.3,"headline":"Juniper Junos OS EX Series Missing Authentication for Critical Function","id":"CVE-2023-36847","kev_date_added":"2023-11-13","published":"2023-08-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Juniper Networks"]},"summary":"An unauthenticated adjacent attacker can cause a denial of service by sending malformed LACP packets to Juniper QFX5000 and EX Series switches.","url":"https://insights.sbomify.com/CVE-2024-30388/"}
