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-2023-6340 in the wild and no public exploit code.\n\nAffected product: SonicWall Capture 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-2023-6340/ (Markdown: https://insights.sbomify.com/CVE-2023-6340/index.md)","id":"CVE-2023-6340","markdown":"https://insights.sbomify.com/CVE-2023-6340/index.md","name":"CVE-2023-6340","record":{"aliases":["GHSA-pvh3-5rhh-wcg5"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SonicWall client software","requires_auth":"low_privilege","summary":"A stack-based buffer overflow in the sfpmonitor.sys driver allows attackers to cause a denial of service in SonicWall Capture Client and NetExtender.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sonicwall","cpe":[{"product":"capture_client","vendor":"sonicwall"},{"product":"netextender","vendor":"sonicwall"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"SonicWall Capture Client version 3.7.10, NetExtender client version 10.2.337 and earlier versions are installed with sfpmonitor.sys driver.
