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-2024-21590 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-2024-21590/ (Markdown: https://insights.sbomify.com/CVE-2024-21590/index.md)","id":"CVE-2024-21590","markdown":"https://insights.sbomify.com/CVE-2024-21590/index.md","name":"CVE-2024-21590","record":{"aliases":["GHSA-53r8-h9fr-mwc7"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Junos OS Evolved","requires_auth":"none","summary":"An unauthenticated attacker within the MPLS domain can cause a Denial of Service on the Routing Engine by sending crafted transit MPLS IPv4 packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos_os_evolved","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:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An Improper Input Validation vulnerability in Juniper Tunnel Driver (jtd) and ICMP module of Juniper Networks Junos OS Evolved allows an unauthenticated attacker within the MPLS administrative domain to send specifically crafted packets to the Routing Engine (RE) to cause a Denial of Service (DoS). \n\nWhen specifically crafted transit MPLS IPv4 packets are received by the Packet Forwarding Engine (PFE), these packets are internally forwarded to the RE. Continued receipt of these packets may create a sustained Denial of Service (DoS) condition.\n\nThis issue affects Juniper Networks Junos OS:\n\n  *  All versions before 21.2R3-S8-EVO;\n  *  from 21.4-EVO before 21.4R3-S6-EVO;\n  *  from 22.2-EVO before 22.2R3-S4-EVO;\n  *  from 22.3-EVO before 22.3R3-S3-EVO;\n  *  from 22.4-EVO before 22.4R3-EVO;\n  *  from 23.2-EVO before 23.2R2-EVO.\n  *  from 23.4-EVO before 23.4R1-S1-EVO.","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 Evolved: Packets which are not destined to the device can reach the RE","id":"CVE-2024-21590","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"juniper:junos_os_evolved","products":["juniper:junos_os_evolved"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Junos OS: SRX Series and EX Series: Security Vulnerability in J-web allows a preAuth Remote Code Execution","id":"CVE-2024-21591"},"packages":[],"prev":{"headline":"Paragon Active Assurance Control Center: Information disclosure vulnerability","id":"CVE-2024-21589"},"products":["Junos OS Evolved"],"published":"2024-04-12","related":[{"cvss_score":9.3,"headline":"Junos OS Evolved: PTX Series: A vulnerability allows a unauthenticated, network-based attacker to execute code as root","id":"CVE-2026-21902","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":8.8,"headline":"Junos OS Evolved: Shell Injection vulnerability in the gNOI server","id":"CVE-2023-28983","kev_date_added":null,"published":"2023-04-17"},{"cvss_score":8.7,"headline":"Denial of service in Junos OS Evolved","id":"CVE-2025-21599","kev_date_added":null,"published":"2025-01-09"},{"cvss_score":8.7,"headline":"Junos OS Evolved: TCP session state is not always cleared on the Routing Engine leading to DoS","id":"CVE-2024-47502","kev_date_added":null,"published":"2024-10-11"},{"cvss_score":8.7,"headline":"Junos OS Evolved: ACX 7000 Series: Protocol specific DDoS configuration affects other protocols","id":"CVE-2024-39531","kev_date_added":null,"published":"2024-07-11"},{"cvss_score":8.7,"headline":"Junos OS Evolved: A high rate of SSH connections causes a Denial of Service","id":"CVE-2024-39562","kev_date_added":null,"published":"2024-07-10"},{"cvss_score":8.5,"headline":"Junos OS Evolved: Local, authenticated attacker can gain privileged access to FPCs","id":"CVE-2026-33788","kev_date_added":null,"published":"2026-04-09"}],"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":"2024-08-01","vendors":["Juniper Networks"]},"summary":"An unauthenticated attacker within the MPLS domain can cause a Denial of Service on the Routing Engine by sending crafted transit MPLS IPv4 packets.","url":"https://insights.sbomify.com/CVE-2024-21590/"}
