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-2019-6840 in the wild and no public exploit code.\n\nAffected product: Schneider Electric SE U.motion Server. 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-2019-6840/ (Markdown: https://insights.sbomify.com/CVE-2019-6840/index.md)","id":"CVE-2019-6840","markdown":"https://insights.sbomify.com/CVE-2019-6840/index.md","name":"CVE-2019-6840","record":{"aliases":["GHSA-j26m-33c4-8m5q"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"U.motion KNX Server","requires_auth":"none","summary":"An attacker can execute arbitrary commands on Schneider Electric U.motion KNX servers by sending a crafted message exploiting a format string vulnerability.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"meg6260-0410_firmware","vendor":"schneider-electric"},{"product":"meg6260-0415_firmware","vendor":"schneider-electric"},{"product":"meg6501-0001_firmware","vendor":"schneider-electric"},{"product":"meg6501-0002_firmware","vendor":"schneider-electric"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"A Format String: CWE-134 vulnerability exists in U.motion Server (MEG6501-0001 - U.motion KNX server, MEG6501-0002 - U.motion KNX Server Plus, MEG6260-0410 - U.motion KNX Server Plus, Touch 10, MEG6260-0415 - U.motion KNX Server Plus, Touch 15), which could allow an attacker to send a crafted message to the target server, thereby causing arbitrary commands to be executed.","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":"Code injection in U.motion Server","id":"CVE-2019-6840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Modicon M580, Modicon M340, and Modicon BMxCRA / 140CRA modules (see notification for version info)","id":"CVE-2019-6841"},"packages":[],"prev":{"headline":"File upload in U.motion Servers (MEG6501-0001 - U.motion KNX server, MEG6501-0002 - U.motion KNX Server Plus, MEG6260-0410 - U.motion KNX Server Plus, Touch 10, and MEG6260-0415 - U.motion KNX Server Plus, Touch 1)","id":"CVE-2019-6839"},"products":["U.motion Server"],"published":"2019-09-17","related":[{"cvss_score":9.1,"headline":"Server-side request forgery in U.motion Server","id":"CVE-2019-6837","kev_date_added":null,"published":"2019-09-17"},{"cvss_score":8.8,"headline":"File upload in U.motion Servers (MEG6501-0001 - U.motion KNX server, MEG6501-0002 - U.motion KNX Server Plus, MEG6260-0410 - U.motion KNX Server Plus, Touch 10, and MEG6260-0415 - U.motion KNX Server Plus, Touch 1)","id":"CVE-2019-6839","kev_date_added":null,"published":"2019-09-17"},{"cvss_score":7.5,"headline":"Missing authorization in U.motion Servers (MEG6501-0001 - U.motion KNX server, MEG6501-0002 - U.motion KNX Server Plus, MEG6260-0410 - U.motion KNX Server Plus, Touch 10, and MEG6260-0415 - U.motion KNX Server Plus, Touch 1)","id":"CVE-2019-6836","kev_date_added":null,"published":"2019-09-17"},{"cvss_score":6.5,"headline":"Missing authorization in U.motion Servers (MEG6501-0001 - U.motion KNX server, MEG6501-0002 - U.motion KNX Server Plus, MEG6260-0410 - U.motion KNX Server Plus, Touch 10, and MEG6260-0415 - U.motion KNX Server Plus, Touch 1)","id":"CVE-2019-6838","kev_date_added":null,"published":"2019-09-17"},{"cvss_score":5.4,"headline":"Cross-site scripting in U.motion Server","id":"CVE-2019-6835","kev_date_added":null,"published":"2019-09-17"}],"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":"2024-08-04","vendors":["Schneider Electric SE"]},"summary":"An attacker can execute arbitrary commands on Schneider Electric U.motion KNX servers by sending a crafted message exploiting a format string vulnerability.","url":"https://insights.sbomify.com/CVE-2019-6840/"}
