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-2020-3164 in the wild and no public exploit code.\n\nAffected product: Cisco Email Security Appliance. 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-2020-3164/ (Markdown: https://insights.sbomify.com/CVE-2020-3164/index.md)","id":"CVE-2020-3164","markdown":"https://insights.sbomify.com/CVE-2020-3164/index.md","name":"CVE-2020-3164","record":{"aliases":["GHSA-2whj-38mw-g8jm"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Security Appliance","requires_auth":"none","summary":"Unauthenticated remote attackers can cause high CPU usage and degrade performance on Cisco ESA, WSA, and SMA devices via malformed HTTP requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"cloud_email_security","vendor":"cisco"},{"product":"content_security_management_appliance","vendor":"cisco"},{"product":"email_security_appliance","vendor":"cisco"},{"product":"web_security_appliance","vendor":"cisco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the web-based management interface of Cisco AsyncOS for Cisco Email Security Appliance (ESA), Cisco Web Security Appliance (WSA), and Cisco Content Security Management Appliance (SMA) could allow an unauthenticated remote attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of specific HTTP request headers. An attacker could exploit this vulnerability by sending a malformed HTTP request to an affected device. A successful exploit could allow the attacker to trigger a prolonged status of high CPU utilization relative to the GUI process(es). Upon successful exploitation of this vulnerability, an affected device will still be operative, but its response time and overall performance may be degraded.","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 ESA, Cisco WSA, and Cisco SMA GUI Denial of Service Vulnerability","id":"CVE-2020-3164","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:email_security_appliance","products":["cisco:email_security_appliance","cisco:web_security_appliance"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco NX-OS Software Border Gateway Protocol MD5 Authentication Bypass Vulnerability","id":"CVE-2020-3165"},"packages":[],"prev":{"headline":"Cisco Unified Contact Center Enterprise Denial of Service Vulnerability","id":"CVE-2020-3163"},"products":["Cisco Web Security Appliance (WSA)"],"published":"2020-03-04","related":[{"cvss_score":6.8,"headline":"Cisco Email Security Appliance Shortened URL Denial of Service Vulnerability","id":"CVE-2020-3132","kev_date_added":null,"published":"2020-02-19"}],"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 high CPU usage and degrade performance on Cisco ESA, WSA, and SMA devices via malformed HTTP requests.","url":"https://insights.sbomify.com/CVE-2020-3164/"}
