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-2024-20391 in the wild and no public exploit code.\n\nAffected product: Cisco Secure 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-2024-20391/ (Markdown: https://insights.sbomify.com/CVE-2024-20391/index.md)","id":"CVE-2024-20391","markdown":"https://insights.sbomify.com/CVE-2024-20391/index.md","name":"CVE-2024-20391","record":{"aliases":["GHSA-gmvc-mphj-2pr4"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Secure Client","requires_auth":"none","summary":"An unauthenticated attacker with physical access can bypass authentication in Cisco Secure Client to execute arbitrary code with SYSTEM privileges.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_client","vendor":"cisco"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"A vulnerability in the Network Access Manager (NAM) module of Cisco Secure Client could allow an unauthenticated attacker with physical access to an affected device to elevate privileges to SYSTEM.\r\n\r This vulnerability is due to a lack of authentication on a specific function.
