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-2020-3189 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Threat Defense. 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-2020-3189/ (Markdown: https://insights.sbomify.com/CVE-2020-3189/index.md)","id":"CVE-2020-3189","markdown":"https://insights.sbomify.com/CVE-2020-3189/index.md","name":"CVE-2020-3189","record":{"aliases":["GHSA-hc53-772h-hrgp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco FTD firewall","requires_auth":"none","summary":"Unauthenticated remote attackers can cause a denial of service by repeatedly creating or deleting VPN tunnels, leading to memory depletion and device crashes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"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-401","name":"Missing Release of Memory after Effective Lifetime"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability in the VPN System Logging functionality for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak that can deplete system memory over time, which can cause unexpected system behaviors or device crashes. The vulnerability is due to the system memory not being properly freed for a VPN System Logging event generated when a VPN session is created or deleted. An attacker could exploit this vulnerability by repeatedly creating or deleting a VPN tunnel connection, which could leak a small amount of system memory for each logging event. A successful exploit could allow the attacker to cause system memory depletion, which can lead to a systemwide denial of service (DoS) condition. The attacker does not have any control of whether VPN System Logging is configured or not on the device, but it is enabled by default.","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":"Cisco Firepower Threat Defense Software VPN System Logging Denial of Service Vulnerability","id":"CVE-2020-3189","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:secure_firewall_threat_defense","products":["cisco:secure_firewall_threat_defense"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IOS XR Software IPsec Packet Processor Denial of Service Vulnerability","id":"CVE-2020-3190"},"packages":[],"prev":{"headline":"Cisco Firepower Threat Defense Software Management Interface Denial of Service Vulnerability","id":"CVE-2020-3188"},"products":["Cisco Firepower Threat Defense Software"],"published":"2020-05-06","related":[{"cvss_score":8.6,"headline":"Cisco Firepower Threat Defense Software Generic Routing Encapsulation Tunnel IPv6 Denial of Service Vulnerability","id":"CVE-2020-3179","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":8.6,"headline":"Cisco Firepower 1000 Series SSL/TLS Denial of Service Vulnerability","id":"CVE-2020-3283","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":7.5,"headline":"Cisco Firepower Threat Defense Software Packet Flood Denial of Service Vulnerability","id":"CVE-2020-3255","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":5.3,"headline":"Cisco Firepower Threat Defense Software Management Access List Bypass Vulnerability","id":"CVE-2020-3186","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":5.3,"headline":"Cisco Firepower Threat Defense Software Management Interface Denial of Service Vulnerability","id":"CVE-2020-3188","kev_date_added":null,"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 cause a denial of service by repeatedly creating or deleting VPN tunnels, leading to memory depletion and device crashes.","url":"https://insights.sbomify.com/CVE-2020-3189/"}
