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-2026-40456 in the wild and no public exploit code.\n\nAffected product: LMS. 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-2026-40456/ (Markdown: https://insights.sbomify.com/CVE-2026-40456/index.md)","id":"CVE-2026-40456","markdown":"https://insights.sbomify.com/CVE-2026-40456/index.md","name":"CVE-2026-40456","record":{"aliases":["GHSA-765c-7qf8-cw9w"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LAN Management System","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary OS commands via an unvalidated IP address parameter in LMS, requiring a patch to mitigate.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An OS Command Injection vulnerability exists in LMS (LAN Management System) before commit 9fcb4de due to an IP address parameter being passed to the \"exec()\" function without proper validation, allowing attackers to execute arbitrary operating system commands.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"OS Command Injection in LMS","id":"CVE-2026-40456","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Reflected XSS in LMS","id":"CVE-2026-40457"},"packages":[],"prev":{"headline":"SQL Injection in LMS","id":"CVE-2026-40455"},"products":["LMS"],"published":"2026-06-18","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":"2026-06-18","vendors":["LMS"]},"summary":"Attackers can execute arbitrary OS commands via an unvalidated IP address parameter in LMS, requiring a patch to mitigate.","url":"https://insights.sbomify.com/CVE-2026-40456/"}
