Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-21539 and fix it if it is affected.\n\nWhat it is: CVE-2021-21539 is a medium-severity vulnerability in Integrated Dell Remote Access Controller (iDRAC), published on 30 Apr 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-21539 in the wild and no public exploit code.\n\nAffected product: Integrated Dell Remote Access Controller (iDRAC). 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-2021-21539/ (Markdown: https://insights.sbomify.com/CVE-2021-21539/index.md)","id":"CVE-2021-21539","markdown":"https://insights.sbomify.com/CVE-2021-21539/index.md","name":"CVE-2021-21539","record":{"aliases":["GHSA-mvg3-9cx3-qjv5"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Dell iDRAC firmware","requires_auth":"low_privilege","summary":"Remote authenticated attackers can exploit a race condition in Dell iDRAC9 to gain elevated privileges during concurrent web interface access.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dell","cpe":[{"product":"idrac9_firmware","vendor":"dell"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Dell EMC iDRAC9 versions prior to 4.40.00.00 contain a Time-of-check Time-of-use (TOCTOU) race condition vulnerability.
