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-2016-4926 in the wild and no public exploit code.\n\nAffected product: Juniper Junos Space. 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-2016-4926/ (Markdown: https://insights.sbomify.com/CVE-2016-4926/index.md)","id":"CVE-2016-4926","markdown":"https://insights.sbomify.com/CVE-2016-4926/index.md","name":"CVE-2016-4926","record":{"aliases":["GHSA-cg68-rv98-xxqj"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Junos Space","requires_auth":"none","summary":"Remote attackers can perform administrative tasks without authentication on Junos Space, requiring an upgrade to secure the network management interface.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos_space","vendor":"juniper"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Insufficient authentication vulnerability in Junos Space before 15.2R2 allows remote network based users with access to Junos Space web interface to perform certain administrative tasks without authentication.","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":"Auth bypass in n/a","id":"CVE-2016-4926","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"juniper:junos_space","products":["juniper:junos_space"],"type":"auth_bypass","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2016-4927"},"packages":[],"prev":{"headline":"JUNOSe: Line Card Reset: processor exception 0x68616c74 (halt) task: scheduler, upon receipt of crafted IPv6 packet","id":"CVE-2016-4925"},"products":["n/a"],"published":"2017-03-20","related":[{"cvss_score":10,"headline":"Command injection in n/a","id":"CVE-2014-3412","kev_date_added":null,"published":"2014-05-20"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2014-3413","kev_date_added":null,"published":"2018-04-05"},{"cvss_score":9.8,"headline":"Junos Space: privilege escalation vulnerabilities in Junos Space","id":"CVE-2016-1265","kev_date_added":null,"published":"2017-10-13"},{"cvss_score":9.8,"headline":"Junos Space: Authentication bypass vulnerability","id":"CVE-2017-10622","kev_date_added":null,"published":"2017-10-13"},{"cvss_score":9.4,"headline":"Junos Space: Stored cross-site scripting vulnerability in web application","id":"CVE-2025-59978","kev_date_added":null,"published":"2025-10-09"},{"cvss_score":8.8,"headline":"Junos Space: Reflected Cross-site Scripting vulnerability in OpenNMS","id":"CVE-2018-0046","kev_date_added":null,"published":"2018-10-10"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can perform administrative tasks without authentication on Junos Space, requiring an upgrade to secure the network management interface.","url":"https://insights.sbomify.com/CVE-2016-4926/"}
