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-2023-4996 in the wild and no public exploit code.\n\nAffected product: Netskope 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-2023-4996/ (Markdown: https://insights.sbomify.com/CVE-2023-4996/index.md)","id":"CVE-2023-4996","markdown":"https://insights.sbomify.com/CVE-2023-4996/index.md","name":"CVE-2023-4996","record":{"aliases":["GHSA-ccf8-r983-v699"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Netskope Client","requires_auth":"low_privilege","summary":"A local non-admin user can disable the Netskope client service due to missing permission checks, leading to privilege escalation and service disruption.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Netskope","cpe":[{"product":"netskope","vendor":"netskope"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-281","name":"Improper Preservation of Permissions"}],"description":"Netskope was made aware of a security vulnerability in its NSClient product for version 100 \u0026 prior where a malicious non-admin user can disable the Netskope client by using a specially-crafted package.
