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-2019-3581 in the wild and no public exploit code.\n\nAffected product: McAfee Web Gateway. 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-2019-3581/ (Markdown: https://insights.sbomify.com/CVE-2019-3581/index.md)","id":"CVE-2019-3581","markdown":"https://insights.sbomify.com/CVE-2019-3581/index.md","name":"CVE-2019-3581","record":{"aliases":["GHSA-f233-9p3q-5vq9"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Web Gateway","requires_auth":"none","summary":"Remote attackers can cause a denial of service in McAfee Web Gateway by sending a crafted HTTP request parameter due to improper input validation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"mcafee_web_gateway","vendor":"mcafee"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation in the proxy component of McAfee Web Gateway 7.8.2.0 and later allows remote attackers to cause a denial of service via a crafted HTTP request parameter.","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":"McAfee Web Gateway denial of service attack due to Improper Input Validation","id":"CVE-2019-3581","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"McAfee Endpoint Security updates fix a privilege escalation vulnerability","id":"CVE-2019-3582"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2019-3580"},"products":["McAfee Web Gateway"],"published":"2019-01-09","related":[{"cvss_score":10,"headline":"McAfee Web Gateway - Authentication Bypass vulnerability","id":"CVE-2018-6667","kev_date_added":null,"published":"2018-06-26"},{"cvss_score":7.6,"headline":"McAfee Web Gateway (MWG) - Directory Traversal vulnerability","id":"CVE-2018-6677","kev_date_added":null,"published":"2018-07-23"},{"cvss_score":3.4,"headline":"McAfee Web Gateway (MWG) - Configuration/Environment manipulation vulnerability","id":"CVE-2018-6678","kev_date_added":null,"published":"2018-07-23"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["McAfee"]},"summary":"Remote attackers can cause a denial of service in McAfee Web Gateway by sending a crafted HTTP request parameter due to improper input validation.","url":"https://insights.sbomify.com/CVE-2019-3581/"}
