An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-3635 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-2019-3635/ (Markdown: https://insights.sbomify.com/CVE-2019-3635/index.md)","id":"CVE-2019-3635","markdown":"https://insights.sbomify.com/CVE-2019-3635/index.md","name":"CVE-2019-3635","record":{"aliases":["GHSA-6j3c-cmq4-m6hv"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Web Gateway","requires_auth":"none","summary":"Attackers can exfiltrate sensitive data from McAfee Web Gateway users by crafting a webpage that triggers a cross-frame scripting vulnerability.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"web_gateway","vendor":"mcafee"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[],"description":"Exfiltration of Data in McAfee Web Gateway (MWG) 7.8.2.x prior to 7.8.2.12 allows attackers to obtain sensitive data via crafting a complex webpage that will trigger the Web Gateway to block the user accessing an iframe.","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":"MWG Proxy: Cross-Frame Scripting vulnerability","id":"CVE-2019-3635","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"File masquerade attack vulnerability in McAfee Total Protection","id":"CVE-2019-3636"},"packages":[],"prev":{"headline":"Buffer overflow in DLP Endpoint for Windows","id":"CVE-2019-3634"},"products":["McAfee Web Gateway (MWG)"],"published":"2019-08-14","related":[{"cvss_score":9,"headline":"Privilege escalation vulnerability in McAfee Web Gateway (MWG) UI","id":"CVE-2021-23885","kev_date_added":null,"published":"2021-02-17"},{"cvss_score":9,"headline":"Web Gateway (MWG) - Privilege Escalation vulnerability","id":"CVE-2020-7293","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":8.1,"headline":"Web Gateway (MWG) - Reflected Cross Site Scripting vulnerability","id":"CVE-2019-3638","kev_date_added":null,"published":"2019-09-12"},{"cvss_score":7.1,"headline":"MWG UI: Cross-Frame Scripting vulnerability","id":"CVE-2019-3639","kev_date_added":null,"published":"2019-08-14"},{"cvss_score":6.1,"headline":"SWG URL redirection vulnerability","id":"CVE-2022-1254","kev_date_added":null,"published":"2022-04-20"},{"cvss_score":5.7,"headline":"Web Gateway (MWG) - Privilege Escalation vulnerability","id":"CVE-2020-7296","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":5.7,"headline":"Web Gateway (MWG) - Privilege Escalation vulnerability","id":"CVE-2020-7297","kev_date_added":null,"published":"2020-09-15"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["McAfee, LLC"]},"summary":"Attackers can exfiltrate sensitive data from McAfee Web Gateway users by crafting a webpage that triggers a cross-frame scripting vulnerability.","url":"https://insights.sbomify.com/CVE-2019-3635/"}
