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-2021-45656 and fix it if it is affected.\n\nWhat it is: CVE-2021-45656 is a high-severity code injection vulnerability in Netgear D6200 Firmware, published on 26 Dec 2021. 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-2021-45656 in the wild and no public exploit code.\n\nAffected product: Netgear D6200 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-2021-45656/ (Markdown: https://insights.sbomify.com/CVE-2021-45656/index.md)","id":"CVE-2021-45656","markdown":"https://insights.sbomify.com/CVE-2021-45656/index.md","name":"CVE-2021-45656","record":{"aliases":["GHSA-7mw2-5r6h-5932"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code on vulnerable NETGEAR routers via server-side injection flaws.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac2100_firmware","vendor":"netgear"},{"product":"ac2400_firmware","vendor":"netgear"},{"product":"ac2600_firmware","vendor":"netgear"},{"product":"d6200_firmware","vendor":"netgear"},{"product":"d7000_firmware","vendor":"netgear"},{"product":"jr6150_firmware","vendor":"netgear"},{"product":"r6020_firmware","vendor":"netgear"},{"product":"r6050_firmware","vendor":"netgear"},{"product":"r6080_firmware","vendor":"netgear"},{"product":"r6120_firmware","vendor":"netgear"},{"product":"r6220_firmware","vendor":"netgear"},{"product":"r6230_firmware","vendor":"netgear"},{"product":"r6260_firmware","vendor":"netgear"},{"product":"r6700_firmware","vendor":"netgear"},{"product":"r6800_firmware","vendor":"netgear"},{"product":"r6900_firmware","vendor":"netgear"},{"product":"r7450_firmware","vendor":"netgear"},{"product":"rbk20_firmware","vendor":"netgear"},{"product":"rbk40_firmware","vendor":"netgear"},{"product":"rbk50_firmware","vendor":"netgear"},{"product":"rbr20_firmware","vendor":"netgear"},{"product":"rbr40_firmware","vendor":"netgear"},{"product":"rbr50_firmware","vendor":"netgear"},{"product":"rbs20_firmware","vendor":"netgear"},{"product":"rbs40_firmware","vendor":"netgear"},{"product":"rbs50_firmware","vendor":"netgear"},{"product":"rbs50y_firmware","vendor":"netgear"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AC:L/AV:L/A:N/C:H/I:H/PR:L/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Certain NETGEAR devices are affected by server-side injection.
