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-2024-39547 in the wild and no public exploit code.\n\nAffected product: Juniper Networks Junos OS. 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-2024-39547/ (Markdown: https://insights.sbomify.com/CVE-2024-39547/index.md)","id":"CVE-2024-39547","markdown":"https://insights.sbomify.com/CVE-2024-39547/index.md","name":"CVE-2024-39547","record":{"aliases":["GHSA-37f4-v37x-33qj"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Juniper Junos OS","requires_auth":"none","summary":"Unauthenticated attackers can cause high CPU utilization and denial of service in Junos OS by sending crafted TCP traffic to the routing engine.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos_containerized_routing_protocol_daemon","vendor":"juniper"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/AU:Y/R:U","version":"4.0"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"}],"description":"An Improper Handling of Exceptional Conditions vulnerability in the rpd-server of Juniper Networks Junos OS and Junos OS Evolved within cRPD allows an unauthenticated network-based attacker sending crafted TCP traffic to the routing engine (RE) to cause a CPU-based Denial of Service (DoS).\n\nIf specially crafted TCP traffic is received by the control plane, or a TCP session terminates unexpectedly, it will cause increased control plane CPU utilization by the rpd-server process.\n\nWhile not explicitly required, the impact is more severe when RIB sharding is enabled.\n\nTask accounting shows unexpected reads by the RPD Server jobs for shards:\n\nuser@junos\u003e show task accounting detail\n...\nread:RPD Server.0.0.0.0+780.192.168.0.78+48886 TOT:00000003.00379787 MAX:00000000.00080516 RUNS: 233888\\\nread:RPD Server.0.0.0.0+780.192.168.0.78+49144 TOT:00000004.00007565 MAX:00000000.00080360 RUNS: 233888\\\nread:RPD Server.0.0.0.0+780.192.168.0.78+49694 TOT:00000003.00600584 MAX:00000000.00080463 RUNS: 233888\\\nread:RPD Server.0.0.0.0+780.192.168.0.78+50246 TOT:00000004.00346998 MAX:00000000.00080338 RUNS: 233888\\\n\nThis issue affects:\n\nJunos OS with cRPD: \n\n  *  All versions before 21.2R3-S8, \n  *  21.4 before 21.4R3-S7, \n  *  22.1 before 22.1R3-S6, \n  *  22.2 before 22.2R3-S4, \n  *  22.3 before 22.3R3-S3, \n  *  22.4 before 22.4R3-S2, \n  *  23.2 before 23.2R2-S2, \n  *  24.2 before 24.2R2; \n\nJunos OS Evolved with cRPD: \n\n  *  All versions before 21.4R3-S7-EVO, \n  *  22.2 before 22.2R3-S4-EVO, \n  *  22.3 before 22.3R3-S3-EVO, \n  *  22.4 before 22.4R3-S2-EVO, \n  *  23.2 before 23.2R2-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 and Junos OS Evolved: cRPD: Receipt of crafted TCP traffic can trigger high CPU utilization","id":"CVE-2024-39547","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Junos OS Evolved: Receipt of specific packets in the aftmand process will lead to a memory leak","id":"CVE-2024-39548"},"packages":[],"prev":{"headline":"Junos OS Evolved: Local low-privilege user can gain root permissions leading to privilege escalation","id":"CVE-2024-39546"},"products":["Junos OS","Junos OS Evolved"],"published":"2024-10-11","related":[],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-11","vendors":["Juniper Networks"]},"summary":"Unauthenticated attackers can cause high CPU utilization and denial of service in Junos OS by sending crafted TCP traffic to the routing engine.","url":"https://insights.sbomify.com/CVE-2024-39547/"}
