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-2020-3196 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-2020-3196/ (Markdown: https://insights.sbomify.com/CVE-2020-3196/index.md)","id":"CVE-2020-3196","markdown":"https://insights.sbomify.com/CVE-2020-3196/index.md","name":"CVE-2020-3196","record":{"aliases":["GHSA-57vc-vmwg-pg76"],"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 exhaust memory via SSL/TLS connections, causing a denial of service on Cisco ASA and FTD devices.","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":"asa_5505_firmware","vendor":"cisco"},{"product":"asa_5510_firmware","vendor":"cisco"},{"product":"asa_5512-x_firmware","vendor":"cisco"},{"product":"asa_5515-x_firmware","vendor":"cisco"},{"product":"asa_5520_firmware","vendor":"cisco"},{"product":"asa_5525-x_firmware","vendor":"cisco"},{"product":"asa_5540_firmware","vendor":"cisco"},{"product":"asa_5545-x_firmware","vendor":"cisco"},{"product":"asa_5550_firmware","vendor":"cisco"},{"product":"asa_5555-x_firmware","vendor":"cisco"},{"product":"asa_5580_firmware","vendor":"cisco"},{"product":"asa_5585-x_firmware","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) handler of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to exhaust memory resources on the affected device, leading to a denial of service (DoS) condition. The vulnerability is due to improper resource management for inbound SSL/TLS connections. An attacker could exploit this vulnerability by establishing multiple SSL/TLS connections with specific conditions to the affected device. A successful exploit could allow the attacker to exhaust the memory on the affected device, causing the device to stop accepting new SSL/TLS connections and resulting in a DoS condition for services on the device that process SSL/TLS traffic. Manual intervention is required to recover an affected device.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2020-3196","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:adaptive_security_appliance_software","products":["cisco:adaptive_security_appliance_software","cisco:secure_firewall_threat_defense"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Meetings App Missing TURN Server Credentials Expiration Vulnerability","id":"CVE-2020-3197"},"packages":[],"prev":{"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2020-3195"},"products":["Cisco Adaptive Security Appliance (ASA) Software"],"published":"2020-05-06","related":[{"cvss_score":9.9,"headline":"Cisco Secure Firewall Adaptive Security Appliance (ASA) and Secure Firewall Threat Defense (FTD) Buffer Overflow","id":"CVE-2025-20333","kev_date_added":"2025-09-25","published":"2025-09-25"},{"cvss_score":8.8,"headline":"Cisco Adaptive Security Appliance (ASA) SNMP Buffer Overflow","id":"CVE-2016-6366","kev_date_added":"2022-05-24","published":"2016-08-18"},{"cvss_score":8.6,"headline":"Cisco Secure Firewall Adaptive Security Appliance (ASA) and Secure Firewall Threat Defense (FTD) Heap Inspection","id":"CVE-2026-20349","kev_date_added":"2026-08-11","published":"2026-08-11"},{"cvss_score":8.6,"headline":"Cisco ASA and FTD Denial of Service","id":"CVE-2024-20353","kev_date_added":"2024-04-24","published":"2024-04-24"},{"cvss_score":7.8,"headline":"Cisco Adaptive Security Appliance (ASA) CLI Remote Code Execution","id":"CVE-2016-6367","kev_date_added":"2022-05-24","published":"2016-08-18"},{"cvss_score":7.5,"headline":"Cisco ASA and FTD Read-Only Path Traversal","id":"CVE-2020-3452","kev_date_added":"2021-11-03","published":"2020-07-22"},{"cvss_score":7.5,"headline":"Cisco ASA and FTD Information Disclosure","id":"CVE-2020-3259","kev_date_added":"2024-02-15","published":"2020-05-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-15","vendors":["Cisco"]},"summary":"Unauthenticated remote attackers can exhaust memory via SSL/TLS connections, causing a denial of service on Cisco ASA and FTD devices.","url":"https://insights.sbomify.com/CVE-2020-3196/"}
