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-2026-101983 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-2026-101983/ (Markdown: https://insights.sbomify.com/CVE-2026-101983/index.md)","id":"CVE-2026-101983","markdown":"https://insights.sbomify.com/CVE-2026-101983/index.md","name":"CVE-2026-101983","record":{"aliases":["GHSA-wg6r-2r3p-3vc7"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Juniper Junos OS","requires_auth":"none","summary":"An unauthenticated attacker can achieve remote code execution and denial of service via a stack-based buffer overflow in J-Web when virtual-domain is configured.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A Stack-based Buffer Overflow vulnerability in the httpd process of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network attacker to cause remote code execution and denial of service via a J-Web virtual-domain configured.","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 remote code execution when J-Web virtual-domain is configured","id":"CVE-2026-101983","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Junos OS and Junos OS Evolved: A BGP peer causes an rpd crash when labeled-unicast aggregate-label is configured","id":"CVE-2026-101984"},"packages":[],"prev":{"headline":"Junos OS and Junos OS Evolved: A EVPN peer causes an rpd crash or root-level compromise when EVPN-VPWS is used","id":"CVE-2026-101982"},"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Juniper Networks"]},"summary":"An unauthenticated attacker can achieve remote code execution and denial of service via a stack-based buffer overflow in J-Web when virtual-domain is configured.","url":"https://insights.sbomify.com/CVE-2026-101983/"}
