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-2024-30390 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-2024-30390/ (Markdown: https://insights.sbomify.com/CVE-2024-30390/index.md)","id":"CVE-2024-30390","markdown":"https://insights.sbomify.com/CVE-2024-30390/index.md","name":"CVE-2024-30390","record":{"aliases":["GHSA-6w72-x59c-h2c9"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Junos OS Evolved","requires_auth":"none","summary":"An unauthenticated attacker can cause a limited Denial of Service on the management plane by bypassing connection limits.","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":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"An Improper Restriction of Excessive Authentication Attempts vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a limited Denial of Service (DoS) to the management plane.\n\nWhen an incoming connection was blocked because it exceeded the connections-per-second rate-limit, the system doesn't consider existing connections anymore for subsequent connection attempts so that the connection limit can be exceeded.\nThis issue affects Junos OS Evolved:\n\n  *  All versions before 21.4R3-S4-EVO,\n  *  22.1-EVO versions before 22.1R3-S3-EVO,\n  *  22.2-EVO versions before 22.2R3-S2-EVO, \n  *  22.3-EVO versions before 22.3R2-S1-EVO, 22.3R3-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: Connection limits is not being enforced while the resp. rate limit is being enforced","id":"CVE-2024-30390","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":"Auth bypass in Junos OS","id":"CVE-2024-30391"},"packages":[],"prev":{"headline":"Junos OS: EX4300 Series: Firewall filter not blocking egress traffic","id":"CVE-2024-30389"},"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":"2024-08-02","vendors":["Juniper Networks"]},"summary":"An unauthenticated attacker can cause a limited Denial of Service on the management plane by bypassing connection limits.","url":"https://insights.sbomify.com/CVE-2024-30390/"}
