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-2019-1736 in the wild and no public exploit code.\n\nAffected product: Cisco Identity Services Engine. 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-2019-1736/ (Markdown: https://insights.sbomify.com/CVE-2019-1736/index.md)","id":"CVE-2019-1736","markdown":"https://insights.sbomify.com/CVE-2019-1736/index.md","name":"CVE-2019-1736","record":{"aliases":["GHSA-pwvv-633w-65j9"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco UCS Servers","requires_auth":"high_privilege","summary":"An authenticated physical attacker can bypass UEFI Secure Boot to load compromised firmware images on Cisco UCS servers.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"fmc1000-k9_bios","vendor":"cisco"},{"product":"fmc1000-k9_firmware","vendor":"cisco"},{"product":"fmc2500-k9_bios","vendor":"cisco"},{"product":"fmc2500-k9_firmware","vendor":"cisco"},{"product":"fmc4500-k9_bios","vendor":"cisco"},{"product":"fmc4500-k9_firmware","vendor":"cisco"},{"product":"identity_services_engine","vendor":"cisco"},{"product":"sns-3515-k9_bios","vendor":"cisco"},{"product":"sns-3515-k9_firmware","vendor":"cisco"},{"product":"sns-3595-k9_bios","vendor":"cisco"},{"product":"sns-3595-k9_firmware","vendor":"cisco"},{"product":"sns-3615-k9_bios","vendor":"cisco"},{"product":"sns-3615-k9_firmware","vendor":"cisco"},{"product":"sns-3655-k9_bios","vendor":"cisco"},{"product":"sns-3655-k9_firmware","vendor":"cisco"},{"product":"sns-3695-k9_bios","vendor":"cisco"},{"product":"sns-3695-k9_firmware","vendor":"cisco"},{"product":"tg5004-k9-rf_bios","vendor":"cisco"},{"product":"tg5004-k9-rf_firmware","vendor":"cisco"},{"product":"tg5004-k9_bios","vendor":"cisco"},{"product":"tg5004-k9_firmware","vendor":"cisco"},{"product":"unified_computing_system","vendor":"cisco"}],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:P/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"A vulnerability in the firmware of the Cisco UCS C-Series Rack Servers could allow an authenticated, physical attacker to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot validation checks and load a compromised software image on an affected device. The vulnerability is due to improper validation of the server firmware upgrade images. An attacker could exploit this vulnerability by installing a server firmware version that would allow the attacker to disable UEFI Secure Boot. A successful exploit could allow the attacker to bypass the signature validation checks that are done by UEFI Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco.","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":"Multiple Cisco UCS-Based Products UEFI Secure Boot Bypass Vulnerability","id":"CVE-2019-1736","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:identity_services_engine","products":["cisco:identity_services_engine","cisco:unified_computing_system"],"type":"security_feature_bypass","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IOS and IOS XE Software IP Service Level Agreement Denial of Service Vulnerability","id":"CVE-2019-1737"},"packages":[],"prev":{"headline":"Cisco NX-OS Software Command Injection Vulnerability (CVE-2019-1735)","id":"CVE-2019-1735"},"products":["Cisco Identity Services Engine Software"],"published":"2020-09-23","related":[],"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":"2024-11-13","vendors":["Cisco"]},"summary":"An authenticated physical attacker can bypass UEFI Secure Boot to load compromised firmware images on Cisco UCS servers.","url":"https://insights.sbomify.com/CVE-2019-1736/"}
