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-2026-102047 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-2026-102047/ (Markdown: https://insights.sbomify.com/CVE-2026-102047/index.md)","id":"CVE-2026-102047","markdown":"https://insights.sbomify.com/CVE-2026-102047/index.md","name":"CVE-2026-102047","record":{"aliases":["GHSA-w88x-j48x-p6wf"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Juniper Junos OS","requires_auth":"none","summary":"An adjacent attacker can cause a denial of service in Layer 2 control protocols by sending crafted MVRP frames to enabled interfaces.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[],"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/AU:Y/R:A/V:C/RE:M","version":"4.0"},"cwes":[{"id":"CWE-1288","name":"Improper Validation of Consistency within Input"}],"description":"An Improper Validation of Consistency within Input vulnerability in the l2cpd process of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated Layer 2 attacker to cause a denial of service in associated Layer 2 control protocols via a crafted MVRP Ethernet frame sent to an MVRP-enabled interface.","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: An attacker causes l2cpd denial of service when MVRP is used","id":"CVE-2026-102047","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Junos OS: An attacker causes l2cpd crash when FNP is used with VLAN-VPLS encapsulation enabled","id":"CVE-2026-102048"},"packages":[],"prev":{"headline":"Junos OS: MX Series: An attacker causes a Routing Engine denial of service when SCTP service is used","id":"CVE-2026-102046"},"products":["Junos OS","Junos OS Evolved"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-14","vendors":["Juniper Networks"]},"summary":"An adjacent attacker can cause a denial of service in Layer 2 control protocols by sending crafted MVRP frames to enabled interfaces.","url":"https://insights.sbomify.com/CVE-2026-102047/"}
