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-2021-27665 in the wild and no public exploit code.\n\nAffected product: Johnson Controls exacqVision Web Service. 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-2021-27665/ (Markdown: https://insights.sbomify.com/CVE-2021-27665/index.md)","id":"CVE-2021-27665","markdown":"https://insights.sbomify.com/CVE-2021-27665/index.md","name":"CVE-2021-27665","record":{"aliases":["GHSA-vhxw-gj92-g74w"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Video surveillance server","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial-of-service condition in exacqVision Server via an integer overflow in a crafted script.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[{"product":"exacqvision_server","vendor":"johnsoncontrols"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An unauthenticated remote user could exploit a potential integer overflow condition in the exacqVision Server with a specially crafted script and cause denial-of-service condition.","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 Server 32-bit","id":"CVE-2021-27665","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in n/a","id":"CVE-2021-27668"},"packages":[],"prev":{"headline":"exacqVision Web Service","id":"CVE-2021-27664"},"products":["exacqVision Web Service"],"published":"2021-10-11","related":[{"cvss_score":6.7,"headline":"exacqVision Server Unquoted Service Path","id":"CVE-2019-7590","kev_date_added":null,"published":"2019-07-19"},{"cvss_score":6.4,"headline":"exacqVison - TLS certificate validation","id":"CVE-2024-32865","kev_date_added":null,"published":"2024-08-01"}],"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":"An unauthenticated remote attacker can cause a denial-of-service condition in exacqVision Server via an integer overflow in a crafted script.","url":"https://insights.sbomify.com/CVE-2021-27665/"}
