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-2020-3283 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-2020-3283/ (Markdown: https://insights.sbomify.com/CVE-2020-3283/index.md)","id":"CVE-2020-3283","markdown":"https://insights.sbomify.com/CVE-2020-3283/index.md","name":"CVE-2020-3283","record":{"aliases":["GHSA-v2w7-xjpq-rmv5"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Firepower 1000","requires_auth":"none","summary":"Unauthenticated remote attackers can cause a denial of service on Cisco Firepower 1000 devices by sending crafted SSL/TLS messages, triggering a crash and reload.","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-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) handler of Cisco Firepower Threat Defense (FTD) Software when running on the Cisco Firepower 1000 Series platform could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to a communication error between internal functions. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message to an affected device. A successful exploit could allow the attacker to cause a buffer underrun, which leads to a crash. The crash causes the affected device to reload.","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 1000 Series SSL/TLS Denial of Service Vulnerability","id":"CVE-2020-3283","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 Enhanced Preboot eXecution Environment Unsigned Code Execution Vulnerability","id":"CVE-2020-3284"},"packages":[],"prev":{"headline":"Cisco Unified Communications Products Cross-Site Scripting Vulnerability","id":"CVE-2020-3282"},"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 Threat Defense Software VPN System Logging Denial of Service Vulnerability","id":"CVE-2020-3189","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 on Cisco Firepower 1000 devices by sending crafted SSL/TLS messages, triggering a crash and reload.","url":"https://insights.sbomify.com/CVE-2020-3283/"}
