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-2021-47663 in the wild and no public exploit code.\n\nAffected product: Franka Emika Robot. 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-2021-47663/ (Markdown: https://insights.sbomify.com/CVE-2021-47663/index.md)","id":"CVE-2021-47663","markdown":"https://insights.sbomify.com/CVE-2021-47663/index.md","name":"CVE-2021-47663","record":{"aliases":["GHSA-wwjc-h7f8-cqv5"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial robot controller","requires_auth":"none","summary":"An unauthenticated attacker can guess session IDs due to weak JWT implementation, allowing user impersonation and full system access on Franka Emika robots.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Due to improper JSON Web Tokens implementation an unauthenticated remote attacker can guess a valid session ID and therefore impersonate a user to gain full access.","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":"Improper session handling","id":"CVE-2021-47663","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Enumeration of valid user names","id":"CVE-2021-47664"},"packages":[],"prev":{"headline":"Unauthenticated remote shutdown of the cobot","id":"CVE-2021-47662"},"products":["Franka Emika Robot"],"published":"2025-04-24","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":"total"},"state":"PUBLISHED","updated":"2025-04-24","vendors":["Franka Robotics"]},"summary":"An unauthenticated attacker can guess session IDs due to weak JWT implementation, allowing user impersonation and full system access on Franka Emika robots.","url":"https://insights.sbomify.com/CVE-2021-47663/"}
