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-2024-21778 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-2024-21778/ (Markdown: https://insights.sbomify.com/CVE-2024-21778/index.md)","id":"CVE-2024-21778","markdown":"https://insights.sbomify.com/CVE-2024-21778/index.md","name":"CVE-2024-21778","record":{"aliases":["GHSA-pjqw-c568-j595"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Realtek RTL819x SDK","requires_auth":"high_privilege","summary":"A heap-based buffer overflow in Realtek RTL819x SDK allows arbitrary code execution via a malicious .dat file, impacting devices using this firmware.","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-122","name":"Heap-based Buffer Overflow"}],"description":"A heap-based buffer overflow vulnerability exists in the configuration file mib_init_value_array functionality of Realtek rtl819x Jungle SDK v3.4.11.
