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-2021-27656 in the wild and no public exploit code.\n\nAffected product: Johnson Controls exacqVision Web Service version 20.12.2.0 and prior. 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-2021-27656/ (Markdown: https://insights.sbomify.com/CVE-2021-27656/index.md)","id":"CVE-2021-27656","markdown":"https://insights.sbomify.com/CVE-2021-27656/index.md","name":"CVE-2021-27656","record":{"aliases":["GHSA-4v7v-2c44-w644"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Video surveillance software","requires_auth":"none","summary":"Unauthenticated attackers can view sensitive system-level information about the exacqVision Web Service and operating system.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[{"product":"exacqvision_web_service","vendor":"johnsoncontrols"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A vulnerability in exacqVision Web Service 20.12.2.0 and prior could allow an unauthenticated attacker to view system-level information about the exacqVision Web Service and the operating system.","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":"exacqVision Web Services - Information Exposure","id":"CVE-2021-27656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Metasys Improper Privilege Management","id":"CVE-2021-27657"},"packages":[],"prev":{"headline":"Auth bypass in Pega Infinity","id":"CVE-2021-27654"},"products":["exacqVision Web Service version 20.12.2.0 and prior"],"published":"2021-03-18","related":[{"cvss_score":9.8,"headline":"exacqVision Web Service","id":"CVE-2021-27664","kev_date_added":null,"published":"2021-10-11"},{"cvss_score":6.8,"headline":"exacqVision CORS","id":"CVE-2024-32862","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":6.8,"headline":"exacqVison - CSRF issues with Web Service","id":"CVE-2024-32863","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":6.4,"headline":"exacqVison - HTTPS Session Establishment","id":"CVE-2024-32864","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":5.7,"headline":"exacqVison - Token Disclosed in URL","id":"CVE-2024-32931","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":5.3,"headline":"exacqVision Web Service CSS","id":"CVE-2021-27659","kev_date_added":null,"published":"2021-06-24"}],"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":"2024-09-17","vendors":["Johnson Controls"]},"summary":"Unauthenticated attackers can view sensitive system-level information about the exacqVision Web Service and operating system.","url":"https://insights.sbomify.com/CVE-2021-27656/"}
