Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20043 in the wild and no public exploit code.\n\nAffected product: SonicWall SMA100. 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-2021-20043/ (Markdown: https://insights.sbomify.com/CVE-2021-20043/index.md)","id":"CVE-2021-20043","markdown":"https://insights.sbomify.com/CVE-2021-20043/index.md","name":"CVE-2021-20043","record":{"aliases":["GHSA-857m-46rq-rj5c"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SonicWall SSL VPN","requires_auth":"low_privilege","summary":"Remote authenticated attackers can execute arbitrary code via a heap-based buffer overflow in the getBookmarks method of SonicWall SMA100 appliances.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sonicwall","cpe":[{"product":"sma_200_firmware","vendor":"sonicwall"},{"product":"sma_210_firmware","vendor":"sonicwall"},{"product":"sma_400_firmware","vendor":"sonicwall"},{"product":"sma_410_firmware","vendor":"sonicwall"},{"product":"sma_500v_firmware","vendor":"sonicwall"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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 in SonicWall SMA100 getBookmarks method allows a remote authenticated attacker to potentially execute code as the nobody user in the appliance.
