An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-28188 in the wild and no public exploit code.\n\nAffected product: ASUS BMC firmware for ASMB8-iKVM. 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-2021-28188/ (Markdown: https://insights.sbomify.com/CVE-2021-28188/index.md)","id":"CVE-2021-28188","markdown":"https://insights.sbomify.com/CVE-2021-28188/index.md","name":"CVE-2021-28188","record":{"aliases":["GHSA-v57h-2cmj-gqr2"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ASUS BMC firmware","requires_auth":"high_privilege","summary":"Remote attackers can cause a buffer overflow in the user modification function, leading to abnormal termination of the web service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"asmb8-ikvm_firmware","vendor":"asus"},{"product":"z10pe-d16_ws_firmware","vendor":"asus"},{"product":"z10pr-d16_firmware","vendor":"asus"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"The specific function in ASUS BMC’s firmware Web management page (Modify user’s information function) does not verify the string length entered by users, resulting in a Buffer overflow vulnerability.
