An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-20402 in the wild and no public exploit code.\n\nAffected product: Cisco Adaptive Security Appliance Software. 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-2024-20402/ (Markdown: https://insights.sbomify.com/CVE-2024-20402/index.md)","id":"CVE-2024-20402","markdown":"https://insights.sbomify.com/CVE-2024-20402/index.md","name":"CVE-2024-20402","record":{"aliases":["GHSA-2jcv-f397-c9m8"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco ASA/FTD","requires_auth":"none","summary":"Unauthenticated remote attackers can cause Cisco ASA and FTD devices to reload unexpectedly via crafted SSL/TLS packets, resulting in a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"adaptive_security_appliance_software","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-788","name":"Access of Memory Location After End of Buffer"}],"description":"A vulnerability in the SSL VPN feature for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition.\r\n\r This vulnerability is due to a logic error in memory management when the device is handling SSL VPN connections.
