It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-27642 in the wild and no public exploit code.\n\nAffected product: Netgear R6400 Firmware. 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-2022-27642/ (Markdown: https://insights.sbomify.com/CVE-2022-27642/index.md)","id":"CVE-2022-27642","markdown":"https://insights.sbomify.com/CVE-2022-27642/index.md","name":"CVE-2022-27642","record":{"aliases":["GHSA-w94x-h737-f6h9"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"none","summary":"Network-adjacent attackers can bypass authentication on NETGEAR R6700v3 routers due to flawed string matching in the httpd service.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"cax80_firmware","vendor":"netgear"},{"product":"lax20_firmware","vendor":"netgear"},{"product":"mr60_firmware","vendor":"netgear"},{"product":"mr80_firmware","vendor":"netgear"},{"product":"ms60_firmware","vendor":"netgear"},{"product":"ms80_firmware","vendor":"netgear"},{"product":"r6400_firmware","vendor":"netgear"},{"product":"r6700_firmware","vendor":"netgear"},{"product":"r6900p_firmware","vendor":"netgear"},{"product":"r7000_firmware","vendor":"netgear"},{"product":"r7000p_firmware","vendor":"netgear"},{"product":"r7100lg_firmware","vendor":"netgear"},{"product":"r7850_firmware","vendor":"netgear"},{"product":"r7900p_firmware","vendor":"netgear"},{"product":"r7960p_firmware","vendor":"netgear"},{"product":"r8000_firmware","vendor":"netgear"},{"product":"r8000p_firmware","vendor":"netgear"},{"product":"r8500_firmware","vendor":"netgear"},{"product":"rax15_firmware","vendor":"netgear"},{"product":"rax200_firmware","vendor":"netgear"},{"product":"rax20_firmware","vendor":"netgear"},{"product":"rax35_firmware","vendor":"netgear"},{"product":"rax38_firmware","vendor":"netgear"},{"product":"rax40_firmware","vendor":"netgear"},{"product":"rax42_firmware","vendor":"netgear"},{"product":"rax43_firmware","vendor":"netgear"},{"product":"rax45_firmware","vendor":"netgear"},{"product":"rax48_firmware","vendor":"netgear"},{"product":"rax50_firmware","vendor":"netgear"},{"product":"rax50s_firmware","vendor":"netgear"},{"product":"rax75_firmware","vendor":"netgear"},{"product":"rax80_firmware","vendor":"netgear"},{"product":"rs400_firmware","vendor":"netgear"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R6700v3 1.0.4.120_10.0.91 routers.
