It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20037 in the wild and no public exploit code.\n\nAffected product: SonicWall Global VPN Client. 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-2021-20037/ (Markdown: https://insights.sbomify.com/CVE-2021-20037/index.md)","id":"CVE-2021-20037","markdown":"https://insights.sbomify.com/CVE-2021-20037/index.md","name":"CVE-2021-20037","record":{"aliases":["GHSA-m3j4-rxwq-wxv7"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SonicWall Global VPN Client","requires_auth":"low_privilege","summary":"Incorrect default file permissions in the SonicWall Global VPN Client installer allow local attackers to escalate privileges and execute arbitrary code.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sonicwall","cpe":[{"product":"global_vpn_client","vendor":"sonicwall"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"SonicWall Global VPN Client 4.10.5 installer (32-bit and 64-bit) incorrect default file permission vulnerability leads to privilege escalation which potentially allows command execution in the host operating system.
