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-2021-20595 in the wild and no public exploit code.\n\nAffected product: Air Conditioning System/Centralized Controllers G-50A; GB-50A; GB-24A; AG-150A-A; AG-150A-J; GB-50ADA-A; GB-50ADA-J; EB-50GU-A; EB-50GU-J; AE-200A; AE-200E; AE-50A; AE-50E; EW-50A; EW-50E; TE-200A; TE-50A; TW-50A; CMS-RMD-J; Air Conditioning System/Expansion Controllers PAC-YG50ECA; Air Conditioning System/BM adapter BAC-HD150. 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-2021-20595/ (Markdown: https://insights.sbomify.com/CVE-2021-20595/index.md)","id":"CVE-2021-20595","markdown":"https://insights.sbomify.com/CVE-2021-20595/index.md","name":"CVE-2021-20595","record":{"aliases":["GHSA-rmww-xfp2-vx9m"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi AC controllers","requires_auth":"none","summary":"Remote unauthenticated attackers can exploit XML External Entity flaws in Mitsubishi air conditioning controllers to disclose data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[{"product":"ae-200a_firmware","vendor":"mitsubishi"},{"product":"ae-200e_firmware","vendor":"mitsubishi"},{"product":"ae-50a_firmware","vendor":"mitsubishi"},{"product":"ae-50e_firmware","vendor":"mitsubishi"},{"product":"ag-150a-a_firmware","vendor":"mitsubishi"},{"product":"ag-150a-j_firmware","vendor":"mitsubishi"},{"product":"cms-rmd-j_firmware","vendor":"mitsubishi"},{"product":"eb-50gu-a_firmware","vendor":"mitsubishi"},{"product":"eb-50gu-j_firmware","vendor":"mitsubishi"},{"product":"ew-50a_firmware","vendor":"mitsubishi"},{"product":"ew-50e_firmware","vendor":"mitsubishi"},{"product":"g-50a_firmware","vendor":"mitsubishi"},{"product":"gb-50a_firmware","vendor":"mitsubishi"},{"product":"gb-50ada-a_firmware","vendor":"mitsubishi"},{"product":"gb-50ada-j_firmware","vendor":"mitsubishi"},{"product":"pac-yg50eca_firmware","vendor":"mitsubishi"},{"product":"te-200a_firmware","vendor":"mitsubishi"},{"product":"te-50a_firmware","vendor":"mitsubishi"},{"product":"tw-50a_firmware","vendor":"mitsubishi"}],"cvss":{"score":8.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"Improper Restriction of XML External Entity Reference vulnerability in Mitsubishi Electric Air Conditioning System/Centralized Controllers (G-50A Ver.3.35 and prior, GB-50A Ver.3.35 and prior, GB-24A Ver.9.11 and prior, AG-150A-A Ver.3.20 and prior, AG-150A-J Ver.3.20 and prior, GB-50ADA-A Ver.3.20 and prior, GB-50ADA-J Ver.3.20 and prior, EB-50GU-A Ver 7.09 and prior, EB-50GU-J Ver 7.09 and prior, AE-200A Ver 7.93 and prior, AE-200E Ver 7.93 and prior, AE-50A Ver 7.93 and prior, AE-50E Ver 7.93 and prior, EW-50A Ver 7.93 and prior, EW-50E Ver 7.93 and prior, TE-200A Ver 7.93 and prior, TE-50A Ver 7.93 and prior, TW-50A Ver 7.93 and prior, CMS-RMD-J Ver.1.30 and prior), Air Conditioning System/Expansion Controllers (PAC-YG50ECA Ver.2.20 and prior) and Air Conditioning System/BM adapter(BAC-HD150 Ver.2.21 and prior) allows a remote unauthenticated attacker to disclose some of data in the air conditioning system or cause a DoS condition by sending specially crafted packets.","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":"XML external entity in Air Conditioning System/Centralized Controllers G-50A;
