An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-20016 in the wild since at least 3 Nov 2021, including in ransomware campaigns.\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-2021-20016/ (Markdown: https://insights.sbomify.com/CVE-2021-20016/index.md)","id":"CVE-2021-20016","markdown":"https://insights.sbomify.com/CVE-2021-20016/index.md","name":"CVE-2021-20016","record":{"aliases":["GHSA-c283-6775-92m9"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SonicWall SSLVPN SMA100","requires_auth":"none","summary":"Remote unauthenticated attackers can exploit SQL injection in SonicWall SMA100 to access sensitive user credentials and session data.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sonicwall","cpe":[{"product":"sma_100_firmware","vendor":"sonicwall"},{"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","vendor":"sonicwall"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"A SQL-Injection vulnerability in the SonicWall SSLVPN SMA100 product allows a remote unauthenticated attacker to perform SQL query to access username password and other session related information.
