It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-27562 in the wild since at least 3 Nov 2021.\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-2021-27562/ (Markdown: https://insights.sbomify.com/CVE-2021-27562/index.md)","id":"CVE-2021-27562","markdown":"https://insights.sbomify.com/CVE-2021-27562/index.md","name":"CVE-2021-27562","record":{"aliases":["GHSA-3352-gx8m-f7v5"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Arm Trusted Firmware","requires_auth":"low_privilege","summary":"Attackers in the non-secure world can trigger system halts, overwrite secure data, or leak secure data via secure function calls.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"trusted_firmware-m","vendor":"trustedfirmware"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In Arm Trusted Firmware M through 1.2, the NS world may trigger a system halt, an overwrite of secure data, or the printing out of secure data when calling secure functions under the NSPE handler mode.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Arm Trusted Firmware Out-of-Bounds Write","id":"CVE-2021-27562","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2021-11-17","knownRansomwareCampaignUse":"Unknown","product":"Trusted Firmware","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Arm","vulnerabilityName":"Arm Trusted Firmware Out-of-Bounds Write Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-27564"},"packages":[],"prev":{"headline":"Yealink Device Management Server-Side Request Forgery (SSRF)","id":"CVE-2021-27561"},"products":["n/a"],"published":"2021-05-25","related":[{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-43619","kev_date_added":null,"published":"2022-03-01"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2023-40271","kev_date_added":null,"published":"2023-09-08"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-32032","kev_date_added":null,"published":"2021-05-21"},{"cvss_score":5.9,"headline":"Missing authorization in n/a","id":"CVE-2021-40327","kev_date_added":null,"published":"2022-01-13"},{"cvss_score":4.7,"headline":"Information disclosure in n/a","id":"CVE-2023-51712","kev_date_added":null,"published":"2024-09-05"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Attackers in the non-secure world can trigger system halts, overwrite secure data, or leak secure data via secure function calls.","url":"https://insights.sbomify.com/CVE-2021-27562/"}
