It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-27643 and fix it if it is affected.\n\nWhat it is: CVE-2022-27643 is a high-severity memory corruption vulnerability in Netgear D6220 Firmware, published on 29 Mar 2023. 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-2022-27643 in the wild and no public exploit code.\n\nAffected product: Netgear D6220 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-2022-27643/ (Markdown: https://insights.sbomify.com/CVE-2022-27643/index.md)","id":"CVE-2022-27643","markdown":"https://insights.sbomify.com/CVE-2022-27643/index.md","name":"CVE-2022-27643","record":{"aliases":["GHSA-h8wj-xxvx-cv2r"],"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 a buffer overflow in SOAP request handling.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"d6220_firmware","vendor":"netgear"},{"product":"d6400_firmware","vendor":"netgear"},{"product":"d7000v2_firmware","vendor":"netgear"},{"product":"dc112a_firmware","vendor":"netgear"},{"product":"ex3700_firmware","vendor":"netgear"},{"product":"ex3800_firmware","vendor":"netgear"},{"product":"ex6120_firmware","vendor":"netgear"},{"product":"ex6130_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":"rax200_firmware","vendor":"netgear"},{"product":"rax75_firmware","vendor":"netgear"},{"product":"rax80_firmware","vendor":"netgear"},{"product":"rs400_firmware","vendor":"netgear"},{"product":"wndr3400_firmware","vendor":"netgear"},{"product":"wnr3500l_firmware","vendor":"netgear"},{"product":"xr300_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-120","name":"Buffer Copy without Checking Size of Input"}],"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.
