An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-3643 and fix it if it is affected.\n\nWhat it is: CVE-2019-3643 is a medium-severity denial of service vulnerability in McAfee, LLC McAfee Web Gateway (MWG), published on 11 Sep 2019. 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-2019-3643 in the wild and no public exploit code.\n\nAffected product: McAfee, LLC McAfee Web Gateway (MWG). 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-2019-3643/ (Markdown: https://insights.sbomify.com/CVE-2019-3643/index.md)","id":"CVE-2019-3643","markdown":"https://insights.sbomify.com/CVE-2019-3643/index.md","name":"CVE-2019-3643","record":{"aliases":["GHSA-jjmf-77v6-6356"],"analysis":{"component_type":"server_software","fix_type":"upgrade","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 scanning proxies by exploiting HTTP/2 rapid reset attacks.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"active_response","vendor":"mcafee"},{"product":"advanced_threat_defense","vendor":"mcafee"},{"product":"enterprise_security_manager","vendor":"mcafee"},{"product":"web_gateway","vendor":"mcafee"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[],"description":"McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9511, potentially leading to a denial of service.
