It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-26264 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-26264/ (Markdown: https://insights.sbomify.com/CVE-2021-26264/index.md)","id":"CVE-2021-26264","markdown":"https://insights.sbomify.com/CVE-2021-26264/index.md","name":"CVE-2021-26264","record":{"aliases":["GHSA-x46h-6fmr-m5fr"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DeltaV DCS Controller","requires_auth":"none","summary":"Attackers can send crafted scripts to restart DeltaV DCS controllers, causing denial of service due to missing authentication.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"deltav_distributed_control_system","vendor":"emerson"},{"product":"deltav_workstation","vendor":"emerson"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"A specially crafted script could cause the DeltaV Distributed Control System Controllers (All Versions) to restart and cause a 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":"Emerson DeltaV Missing Authentication for Critical Function","id":"CVE-2021-26264","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2021-26266"},"packages":[],"prev":{"headline":"Cross-site scripting in Odoo Community","id":"CVE-2021-26263"},"products":["n/a"],"published":"2022-01-28","related":[{"cvss_score":7.8,"headline":"Missing authorization in n/a","id":"CVE-2022-29957","kev_date_added":null,"published":"2022-07-26"},{"cvss_score":5.5,"headline":"Weak cryptography in n/a","id":"CVE-2022-29965","kev_date_added":null,"published":"2022-07-26"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-17","vendors":["n/a"]},"summary":"Attackers can send crafted scripts to restart DeltaV DCS controllers, causing denial of service due to missing authentication.","url":"https://insights.sbomify.com/CVE-2021-26264/"}
