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-2023-36836 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-2023-36836/ (Markdown: https://insights.sbomify.com/CVE-2023-36836/index.md)","id":"CVE-2023-36836","markdown":"https://insights.sbomify.com/CVE-2023-36836/index.md","name":"CVE-2023-36836","record":{"aliases":["GHSA-jmpv-5c86-5fj9"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Juniper Junos OS","requires_auth":"low_privilege","summary":"A local authenticated attacker can cause a routing daemon crash and denial of service in a specific MoFRR configuration scenario.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"},{"product":"junos_os_evolved","vendor":"juniper"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"A Use of an Uninitialized Resource vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with low privileges to cause a Denial of Service (DoS).\n\nOn all Junos OS and Junos OS Evolved platforms, in a Multicast only Fast Reroute (MoFRR) scenario, the rpd process can crash when a a specific low privileged CLI command is executed. The rpd crash will impact all routing protocols until the process has automatically been restarted. As the operational state which makes this issue exploitable is outside the attackers control, this issue is considered difficult to exploit. Continued execution of this command will lead to a sustained DoS.\n\nThis issue affects:\nJuniper Networks Junos OS\n19.4 version 19.4R3-S5 and later versions prior to 19.4R3-S9;\n20.1 version 20.1R2 and later versions;\n20.2 versions prior to 20.2R3-S7;\n20.3 versions prior to 20.3R3-S5;\n20.4 versions prior to 20.4R3-S6;\n21.1 versions prior to 21.1R3-S4;\n21.2 versions prior to 21.2R3-S2;\n21.3 versions prior to 21.3R3-S1;\n21.4 versions prior to 21.4R3;\n22.1 versions prior to 22.1R1-S2, 22.1R2;\n22.2 versions prior to 22.2R2.\n\nJuniper Networks Junos OS Evolved\nAll versions prior to 20.4R3-S6-EVO;\n21.1-EVO version 21.1R1-EVO and later versions;\n21.2-EVO version 21.2R1-EVO and later versions;\n21.3-EVO versions prior to 21.3R3-S1-EVO;\n21.4-EVO versions prior to 21.4R3-EVO;\n22.1-EVO versions prior to 22.1R1-S2-EVO, 22.1R2-EVO;\n22.2-EVO versions prior to 22.2R2-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":"Denial of service in Junos OS","id":"CVE-2023-36836","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"juniper:junos","products":["juniper:junos","juniper:junos_os_evolved"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Junos OS: SRX Series: A flowd core occurs when running a low privileged CLI command","id":"CVE-2023-36838"},"packages":[],"prev":{"headline":"Denial of service in Junos OS","id":"CVE-2023-36835"},"products":["Junos OS","Junos OS Evolved"],"published":"2023-07-14","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":"2024-10-22","vendors":["Juniper Networks"]},"summary":"A local authenticated attacker can cause a routing daemon crash and denial of service in a specific MoFRR configuration scenario.","url":"https://insights.sbomify.com/CVE-2023-36836/"}
