An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-4041 in the wild and no public exploit code.\n\nAffected product: Silicon Labs Gecko Bootloader. 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-2023-4041/ (Markdown: https://insights.sbomify.com/CVE-2023-4041/index.md)","id":"CVE-2023-4041","markdown":"https://insights.sbomify.com/CVE-2023-4041/index.md","name":"CVE-2023-4041","record":{"aliases":["GHSA-hvfc-3xxp-p6hw"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Gecko Bootloader","requires_auth":"none","summary":"Attackers can exploit a buffer overflow in the Gecko Bootloader parser to inject code and bypass authentication during firmware updates.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[{"product":"gecko_bootloader","vendor":"silabs"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"},{"id":"CWE-913","name":"Improper Control of Dynamically-Managed Code Resources"},{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Copy without Checking Size of Input ('Classic Buffer Overflow'), Out-of-bounds Write, Download of Code Without Integrity Check vulnerability in Silicon Labs Gecko Bootloader on ARM (Firmware Update File Parser modules) allows Code Injection, Authentication Bypass.This issue affects \"Standalone\" and \"Application\" versions of Gecko Bootloader.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Second Stage Gecko Bootloader GBL Parser Buffer Overrun Vulnerability","id":"CVE-2023-4041","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Ghostscript: incomplete fix for cve-2020-16305","id":"CVE-2023-4042"},"packages":[],"prev":{"headline":"Missing authorization in Stripe Payment Plugin for WooCommerce","id":"CVE-2023-4040"},"products":["Gecko Bootloader"],"published":"2023-08-23","related":[{"cvss_score":8.3,"headline":"Gecko Standalone Bootloader vulnerability may allow bypassing application secure boot in some Series 2 devices","id":"CVE-2022-24936","kev_date_added":null,"published":"2022-11-02"},{"cvss_score":7.7,"headline":"Integer overflow in Silicon Labs Gecko Bootloader leads to unbounded memory access","id":"CVE-2023-3487","kev_date_added":null,"published":"2023-10-20"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-03","vendors":["Silicon Labs"]},"summary":"Attackers can exploit a buffer overflow in the Gecko Bootloader parser to inject code and bypass authentication during firmware updates.","url":"https://insights.sbomify.com/CVE-2023-4041/"}
