An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-6677 in the wild and no public exploit code.\n\nAffected product: 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-2018-6677/ (Markdown: https://insights.sbomify.com/CVE-2018-6677/index.md)","id":"CVE-2018-6677","markdown":"https://insights.sbomify.com/CVE-2018-6677/index.md","name":"CVE-2018-6677","record":{"aliases":["GHSA-77x6-r257-2x55"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Web Gateway","requires_auth":"high_privilege","summary":"Authenticated administrators can exploit a directory traversal flaw in the McAfee Web Gateway admin interface to gain elevated privileges.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"mcafee_web_gateway","vendor":"mcafee"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Directory Traversal vulnerability in the administrative user interface in McAfee Web Gateway (MWG) MWG 7.8.1.x allows authenticated administrator users to gain elevated privileges via unspecified vectors.","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 (MWG) - Directory Traversal vulnerability","id":"CVE-2018-6677","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"McAfee Web Gateway (MWG) - Configuration/Environment manipulation vulnerability","id":"CVE-2018-6678"},"packages":[],"prev":{"headline":"Privilege escalation vulnerability in McAfee VSE when McTray run with elevated privileges","id":"CVE-2018-6674"},"products":["McAfee Web Gateway (MWG)"],"published":"2018-07-23","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":7.5,"headline":"McAfee Web Gateway denial of service attack due to Improper Input Validation","id":"CVE-2019-3581","kev_date_added":null,"published":"2019-01-09"},{"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":"2024-08-05","vendors":["McAfee"]},"summary":"Authenticated administrators can exploit a directory traversal flaw in the McAfee Web Gateway admin interface to gain elevated privileges.","url":"https://insights.sbomify.com/CVE-2018-6677/"}
