An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-7594 in the wild and no public exploit code.\n\nAffected product: Johnson Controls Metasys versions prior to 9.0. 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-2019-7594/ (Markdown: https://insights.sbomify.com/CVE-2019-7594/index.md)","id":"CVE-2019-7594","markdown":"https://insights.sbomify.com/CVE-2019-7594/index.md","name":"CVE-2019-7594","record":{"aliases":["GHSA-vhqp-g9vm-gc6g"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Building automation system","requires_auth":"none","summary":"Attackers can exploit a hardcoded RC2 key in Metasys servers to bypass encryption and access sensitive Site Management Portal data.","user_interaction":"required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[{"product":"metasys_system","vendor":"johnsoncontrols"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"},{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"Metasys® ADS/ADX servers and NAE/NIE/NCE engines prior to 9.0 make use of a hardcoded RC2 key for certain encryption operations involving the Site Management Portal (SMP).","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":"Metasys use of hardcoded RC2 key","id":"CVE-2019-7594","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Kibana","id":"CVE-2019-7608"},"packages":[],"prev":{"headline":"Metasys use of shared RSA key pairs","id":"CVE-2019-7593"},"products":["Metasys versions prior to 9.0"],"published":"2019-08-20","related":[{"cvss_score":6.8,"headline":"Metasys use of shared RSA key pairs","id":"CVE-2019-7593","kev_date_added":null,"published":"2019-08-20"}],"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":["Johnson Controls"]},"summary":"Attackers can exploit a hardcoded RC2 key in Metasys servers to bypass encryption and access sensitive Site Management Portal data.","url":"https://insights.sbomify.com/CVE-2019-7594/"}
