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-2022-27641 in the wild and no public exploit code.\n\nAffected product: Netgear D7800 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-2022-27641/ (Markdown: https://insights.sbomify.com/CVE-2022-27641/index.md)","id":"CVE-2022-27641","markdown":"https://insights.sbomify.com/CVE-2022-27641/index.md","name":"CVE-2022-27641","record":{"aliases":["GHSA-48fv-6rrf-3cqx"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"none","summary":"Network-adjacent attackers can execute arbitrary code as root on NETGEAR R6700v3 routers via an integer overflow in the NetUSB module.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"d7800_firmware","vendor":"netgear"},{"product":"ex6200_firmware","vendor":"netgear"},{"product":"ex8000_firmware","vendor":"netgear"},{"product":"r6220_firmware","vendor":"netgear"},{"product":"r6230_firmware","vendor":"netgear"},{"product":"r6400_firmware","vendor":"netgear"},{"product":"r6700_firmware","vendor":"netgear"},{"product":"r7000_firmware","vendor":"netgear"},{"product":"r7800_firmware","vendor":"netgear"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700v3 1.0.4.120_10.0.91 routers.
