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-2025-3699 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation AE-200A. 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-2025-3699/ (Markdown: https://insights.sbomify.com/CVE-2025-3699/index.md)","id":"CVE-2025-3699","markdown":"https://insights.sbomify.com/CVE-2025-3699/index.md","name":"CVE-2025-3699","record":{"aliases":["GHSA-73r7-73gp-j7mv"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi HVAC controller","requires_auth":"none","summary":"Remote attackers can bypass authentication to control air conditioning systems, disclose information, and tamper with firmware.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing Authentication for Critical Function vulnerability in Mitsubishi Electric Corporation G-50 all versions, G-50-W all versions, G-50A all versions, GB-50 all versions, GB-50A all versions, GB-24A all versions, G-150AD all versions, AG-150A-A all versions, AG-150A-J all versions, GB-50AD all versions, GB-50ADA-A all versions, GB-50ADA-J all versions, EB-50GU-A all versions, EB-50GU-J all versions, AE-200J all versions, AE-200A all versions, AE-200E all versions, AE-50J all versions, AE-50A all versions, AE-50E all versions, EW-50J all versions, EW-50A all versions, EW-50E all versions, TE-200A all versions, TE-50A all versions, TW-50A all versions, and CMS-RMD-J all versions allows a remote unauthenticated attacker to bypass authentication and then control the air conditioning systems illegally, or disclose information in them by exploiting this vulnerability.
