Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22740 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-2021-22740/ (Markdown: https://insights.sbomify.com/CVE-2021-22740/index.md)","id":"CVE-2021-22740","markdown":"https://insights.sbomify.com/CVE-2021-22740/index.md","name":"CVE-2021-22740","record":{"aliases":["GHSA-6wqw-44p4-565j"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"KNX home automation","requires_auth":"low_privilege","summary":"An attacker can upload unauthorized files to homeLYnk and spaceLYnk devices, resulting in the exposure of sensitive information.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"homelynk_firmware","vendor":"schneider-electric"},{"product":"spacelynk_firmware","vendor":"schneider-electric"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Information Exposure vulnerability exists in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior which could cause information to be exposed when an unauthorized file is uploaded.","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":"File upload in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22740","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Weak cryptography in ClearSCADA (all versions), EcoStruxure Geo SCADA Expert 2019 (all versions), and EcoStruxure Geo SCADA Expert 2020 (V83.7742.1 and prior)","id":"CVE-2021-22741"},"packages":[],"prev":{"headline":"Information disclosure in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22739"},"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":7.8,"headline":"Privilege escalation in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior","id":"CVE-2021-22733","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":"An attacker can upload unauthorized files to homeLYnk and spaceLYnk devices, resulting in the exposure of sensitive information.","url":"https://insights.sbomify.com/CVE-2021-22740/"}
