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-2025-21589 in the wild and no public exploit code.\n\nAffected product: Juniper Networks Session Smart Conductor. 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-2025-21589/ (Markdown: https://insights.sbomify.com/CVE-2025-21589/index.md)","id":"CVE-2025-21589","markdown":"https://insights.sbomify.com/CVE-2025-21589/index.md","name":"CVE-2025-21589","record":{"aliases":["GHSA-vjjg-c428-g9r3"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Juniper Session Smart Router","requires_auth":"none","summary":"A network-based attacker can bypass authentication via an alternate path to gain administrative control of Juniper Session Smart Router devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"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:N","version":"4.0"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"An Authentication Bypass Using an\nAlternate Path or Channel vulnerability in Juniper Networks Session Smart\nRouter may allows a network-based attacker to bypass authentication\nand take administrative control of the device.\n\nThis issue affects Session Smart Router: \n\n  *  from 5.6.7 before 5.6.17, \n  *  from 6.0 before 6.0.8 (affected from 6.0.8),\n\n  *  from 6.1 before 6.1.12-lts, \n  *  from 6.2 before 6.2.8-lts, \n  *  from 6.3 before 6.3.3-r2; \n\nThis issue affects Session Smart Conductor: \n\n  *  from 5.6.7 before 5.6.17, \n  *  from 6.0 before 6.0.8 (affected from 6.0.8),\n\n  *  from 6.1 before 6.1.12-lts, \n  *  from 6.2 before 6.2.8-lts, \n  *  from 6.3 before 6.3.3-r2; \n\nThis issue affects WAN Assurance Managed Routers: \n\n  *  from 5.6.7 before 5.6.17, \n  *  from 6.0 before 6.0.8 (affected from 6.0.8),\n\n  *  from 6.1 before 6.1.12-lts, \n  *  from 6.2 before 6.2.8-lts, \n  *  from 6.3 before 6.3.3-r2.","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":"Session Smart Router, Session Smart Conductor, WAN Assurance Router: API Authentication Bypass vulnerability","id":"CVE-2025-21589","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Juniper Junos OS Improper Isolation or Compartmentalization","id":"CVE-2025-21590"},"packages":[],"prev":{"headline":"Denial of service in MySQL Server","id":"CVE-2025-21588"},"products":["Session Smart Conductor","Session Smart Router","WAN Assurance Managed Router"],"published":"2026-01-27","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":"2026-01-27","vendors":["Juniper Networks"]},"summary":"A network-based attacker can bypass authentication via an alternate path to gain administrative control of Juniper Session Smart Router devices.","url":"https://insights.sbomify.com/CVE-2025-21589/"}
