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-2018-6434 in the wild and no public exploit code.\n\nAffected product: Broadcom Fabric Operating System. 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-2018-6434/ (Markdown: https://insights.sbomify.com/CVE-2018-6434/index.md)","id":"CVE-2018-6434","markdown":"https://insights.sbomify.com/CVE-2018-6434/index.md","name":"CVE-2018-6434","record":{"aliases":["GHSA-gr9m-hh86-87vj"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Brocade Fabric OS","requires_auth":"none","summary":"Attackers can hijack user sessions in the Brocade Fabric OS web interface, leading to unauthorized account access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"brocade","cpe":[{"product":"fabric_operating_system","vendor":"broadcom"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"A vulnerability in the web management interface of Brocade Fabric OS versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow attackers to intercept or manipulate a user's session ID.","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":"Auth bypass in Brocade Fabric OS","id":"CVE-2018-6434","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"broadcom:fabric_operating_system","products":["broadcom:fabric_operating_system"],"type":"auth_bypass","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Brocade Fabric OS","id":"CVE-2018-6435"},"packages":[],"prev":{"headline":"Missing authorization in Brocade Fabric OS","id":"CVE-2018-6433"},"products":["Brocade Fabric OS"],"published":"2018-11-08","related":[{"cvss_score":8.6,"headline":"Broadcom Brocade Fabric OS Code Injection","id":"CVE-2025-1976","kev_date_added":"2025-04-28","published":"2025-04-24"},{"cvss_score":8.3,"headline":"Linux Kernel Heap Out-of-Bounds Write","id":"CVE-2021-22555","kev_date_added":"2025-10-06","published":"2021-07-07"},{"cvss_score":9.8,"headline":"Command injection in Brocade Fabric OS","id":"CVE-2022-33186","kev_date_added":null,"published":"2022-12-08"},{"cvss_score":9.8,"headline":"Hardcoded credentials in Brocade Fabric OS","id":"CVE-2021-27797","kev_date_added":null,"published":"2022-02-21"},{"cvss_score":9.8,"headline":"Code injection in Brocade Fabric OS","id":"CVE-2020-15371","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Memory corruption in Brocade Fabric OS","id":"CVE-2020-15373","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Cross-site scripting in Brocade Fabric OS","id":"CVE-2020-15374","kev_date_added":null,"published":"2020-09-25"}],"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":["Brocade Communications Systems, Inc."]},"summary":"Attackers can hijack user sessions in the Brocade Fabric OS web interface, leading to unauthorized account access.","url":"https://insights.sbomify.com/CVE-2018-6434/"}
