It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22733 and fix it if it is affected.\n\nWhat it is: CVE-2021-22733 is a high-severity vulnerability in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior, published on 26 May 2021. 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-2021-22733 in the wild and no public exploit code.\n\nAffected product: homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior. 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-2021-22733/ (Markdown: https://insights.sbomify.com/CVE-2021-22733/index.md)","id":"CVE-2021-22733","markdown":"https://insights.sbomify.com/CVE-2021-22733/index.md","name":"CVE-2021-22733","record":{"aliases":["GHSA-6xx3-j36r-9j4v"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"KNX home automation","requires_auth":"low_privilege","summary":"Attackers can gain shell access and execute arbitrary code by loading unauthorized files into the system folder of Schneider homeLYnk and spaceLYnk devices.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"homelynk_firmware","vendor":"schneider-electric"},{"product":"spacelynk_firmware","vendor":"schneider-electric"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Improper Privilege Management vulnerability exists in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior which could cause shell access when unauthorized code is loaded into the system folder.","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":"Privilege escalation in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22734"},"packages":[],"prev":{"headline":"Privilege escalation in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22732"},"products":["homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior"],"published":"2021-05-26","related":[{"cvss_score":9.8,"headline":"Hardcoded credentials in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22737","kev_date_added":null,"published":"2021-05-26"},{"cvss_score":9.8,"headline":"Weak cryptography in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22738","kev_date_added":null,"published":"2021-05-26"},{"cvss_score":7.8,"headline":"Privilege escalation in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22732","kev_date_added":null,"published":"2021-05-26"},{"cvss_score":7.5,"headline":"Path traversal in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22736","kev_date_added":null,"published":"2021-05-26"},{"cvss_score":7.5,"headline":"Auth bypass in Wiser for KNX","id":"CVE-2018-7779","kev_date_added":null,"published":"2018-07-03"},{"cvss_score":7.2,"headline":"Security feature bypass in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22734","kev_date_added":null,"published":"2021-05-26"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can gain shell access and execute arbitrary code by loading unauthorized files into the system folder of Schneider homeLYnk and spaceLYnk devices.","url":"https://insights.sbomify.com/CVE-2021-22733/"}
