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-2021-1441 in the wild and no public exploit code.\n\nAffected product: Cisco Ios Xe. 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-2021-1441/ (Markdown: https://insights.sbomify.com/CVE-2021-1441/index.md)","id":"CVE-2021-1441","markdown":"https://insights.sbomify.com/CVE-2021-1441/index.md","name":"CVE-2021-1441","record":{"aliases":["GHSA-75qr-v35g-mjqg"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IOS XE Router","requires_auth":"high_privilege","summary":"An authenticated local attacker with admin credentials can execute unsigned code at boot time by tampering with a diagnostic script, bypassing secure boot verification.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xe","vendor":"cisco"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A vulnerability in the hardware initialization routines of Cisco IOS XE Software for Cisco 1100 Series Industrial Integrated Services Routers and Cisco ESR6300 Embedded Series Routers could allow an authenticated, local attacker to execute unsigned code at system boot time. This vulnerability is due to incorrect validations of parameters passed to a diagnostic script that is executed when the device boots up. An attacker could exploit this vulnerability by tampering with an executable file stored on a device. A successful exploit could allow the attacker to execute unsigned code at boot time and bypass the software image verification check part of the secure boot process of an affected device. To exploit this vulnerability, the attacker would need administrative level credentials (level 15) on the device.","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":"Cisco IOS XE Software Hardware Initialization Routines Arbitrary Code Execution Vulnerability","id":"CVE-2021-1441","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios_xe","products":["cisco:ios_xe"],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IOS XE Software Plug-and-Play Privilege Escalation Vulnerability","id":"CVE-2021-1442"},"packages":[],"prev":{"headline":"Cisco IOS XR Software BGP Resource Public Key Infrastructure Denial of Service Vulnerability","id":"CVE-2021-1440"},"products":["Cisco IOS XE Software"],"published":"2021-03-24","related":[{"cvss_score":10,"headline":"Cisco IOS XE Web UI Privilege Escalation","id":"CVE-2023-20198","kev_date_added":"2023-10-16","published":"2023-10-16"},{"cvss_score":9.8,"headline":"Cisco IOS Software and Cisco IOS XE Software Quality of Service Remote Code Execution","id":"CVE-2018-0151","kev_date_added":"2022-03-03","published":"2018-03-28"},{"cvss_score":7.2,"headline":"Cisco IOS XE Web UI Command Injection","id":"CVE-2023-20273","kev_date_added":"2023-10-23","published":"2023-10-24"},{"cvss_score":10,"headline":"Hardcoded credentials in Cisco IOS XE Software","id":"CVE-2025-20188","kev_date_added":null,"published":"2025-05-07"},{"cvss_score":10,"headline":"Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Remote Code Execution Vulnerability","id":"CVE-2021-34770","kev_date_added":null,"published":"2021-09-23"},{"cvss_score":10,"headline":"Cisco REST API Container for IOS XE Software Authentication Bypass Vulnerability","id":"CVE-2019-12643","kev_date_added":null,"published":"2019-08-28"},{"cvss_score":9.8,"headline":"Cisco IOS XE Software Security Hardening Release","id":"CVE-2026-20272","kev_date_added":null,"published":"2026-08-05"}],"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":"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":"total"},"state":"PUBLISHED","updated":"2024-11-08","vendors":["Cisco"]},"summary":"An authenticated local attacker with admin credentials can execute unsigned code at boot time by tampering with a diagnostic script, bypassing secure boot verification.","url":"https://insights.sbomify.com/CVE-2021-1441/"}
