An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-50240 exists.\n\nAffected product: LevelOne WBR-6013. 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-2023-50240/ (Markdown: https://insights.sbomify.com/CVE-2023-50240/index.md)","id":"CVE-2023-50240","markdown":"https://insights.sbomify.com/CVE-2023-50240/index.md","name":"CVE-2023-50240","record":{"aliases":["GHSA-2qjj-5hcf-4j4c"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Realtek router SDK","requires_auth":"high_privilege","summary":"Remote attackers can execute arbitrary code on Realtek-based routers via stack-based buffer overflows in the RadvdInterfaceParam functionality.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"wbr-6013_firmware","vendor":"level1"},{"product":"rtl819x_jungle_software_development_kit","vendor":"realtek"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Two stack-based buffer overflow vulnerabilities exist in the boa set_RadvdInterfaceParam functionality of Realtek rtl819x Jungle SDK v3.4.11.
