It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-12303 and fix it if it is affected.\n\nWhat it is: CVE-2020-12303 is a high-severity use after free vulnerability in Intel(R) CSME, Intel(R) TXE, published on 12 Nov 2020. 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-2020-12303 in the wild and no public exploit code.\n\nAffected product: Intel(R) CSME, 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-2020-12303/ (Markdown: https://insights.sbomify.com/CVE-2020-12303/index.md)","id":"CVE-2020-12303","markdown":"https://insights.sbomify.com/CVE-2020-12303/index.md","name":"CVE-2020-12303","record":{"aliases":["GHSA-hwgw-9wx9-2x6f"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel CSME/TXE firmware","requires_auth":"low_privilege","summary":"An authenticated local attacker can exploit a use-after-free flaw in Intel CSME/TXE firmware to escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"converged_security_and_manageability_engine","vendor":"intel"},{"product":"trusted_execution_technology","vendor":"intel"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in DAL subsystem for Intel(R) CSME versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70, 13.0.40, 13.30.10, 14.0.45 and 14.5.25, Intel(R) TXE 3.1.80, 4.0.30 may allow an authenticated user to potentially enable escalation of privileges via local 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":"Use after free in Intel(R) CSME, Intel(R) TXE","id":"CVE-2020-12303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in Intel(R) DAL SDK","id":"CVE-2020-12304"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) Driver \u0026 Support Assistant","id":"CVE-2020-12302"},"products":["Intel(R) CSME, Intel(R) TXE"],"published":"2020-11-12","related":[{"cvss_score":7.8,"headline":"Privilege escalation in Intel(R) CSME, Intel TXE","id":"CVE-2020-12297","kev_date_added":null,"published":"2020-11-12"},{"cvss_score":6.8,"headline":"Privilege escalation in Intel(R) CSME versions","id":"CVE-2020-24516","kev_date_added":null,"published":"2021-06-09"},{"cvss_score":6.8,"headline":"Misconfiguration in Intel(R) Boot Guard, Intel(R) CSME, Intel(R) TXE, Intel(R) SPS","id":"CVE-2020-8705","kev_date_added":null,"published":"2020-11-12"},{"cvss_score":6.8,"headline":"Privilege escalation in Intel(R) CSME, Intel(R) TXE","id":"CVE-2020-8745","kev_date_added":null,"published":"2020-11-12"},{"cvss_score":6.7,"headline":"Privilege escalation in Intel(R) CSME versions","id":"CVE-2020-8703","kev_date_added":null,"published":"2021-06-09"},{"cvss_score":6.7,"headline":"Privilege escalation in Intel(R) CSME","id":"CVE-2020-8756","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":"2024-08-04","vendors":["n/a"]},"summary":"An authenticated local attacker can exploit a use-after-free flaw in Intel CSME/TXE firmware to escalate privileges.","url":"https://insights.sbomify.com/CVE-2020-12303/"}
