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-2020-12355 in the wild and no public exploit code.\n\nAffected product: Intel(R) TXE. 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-2020-12355/ (Markdown: https://insights.sbomify.com/CVE-2020-12355/index.md)","id":"CVE-2020-12355","markdown":"https://insights.sbomify.com/CVE-2020-12355/index.md","name":"CVE-2020-12355","record":{"aliases":["GHSA-84pm-g9xr-pqcm"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel TXE firmware","requires_auth":"none","summary":"An attacker with physical access can bypass authentication in Intel TXE firmware to escalate privileges via replay attacks.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"trusted_execution_engine","vendor":"intel"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"Authentication bypass by capture-replay in RPMB protocol message authentication subsystem in Intel(R) TXE versions before 4.0.30 may allow an unauthenticated user to potentially enable escalation of privilege via physical access.","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":"Auth bypass in Intel(R) TXE","id":"CVE-2020-12355","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in Intel(R) AMT","id":"CVE-2020-12356"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) AMT SDK","id":"CVE-2020-12354"},"products":["Intel(R) TXE"],"published":"2020-11-12","related":[{"cvss_score":7.8,"headline":"Use after free in Intel(R) TXE","id":"CVE-2020-8750","kev_date_added":null,"published":"2020-11-12"}],"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":"2025-11-04","vendors":["n/a"]},"summary":"An attacker with physical access can bypass authentication in Intel TXE firmware to escalate privileges via replay attacks.","url":"https://insights.sbomify.com/CVE-2020-12355/"}
