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-2021-45555 and fix it if it is affected.\n\nWhat it is: CVE-2021-45555 is a high-severity command injection vulnerability in Netgear R7900p 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-2021-45555 in the wild and no public exploit code.\n\nAffected product: Netgear R7900p 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-2021-45555/ (Markdown: https://insights.sbomify.com/CVE-2021-45555/index.md)","id":"CVE-2021-45555","markdown":"https://insights.sbomify.com/CVE-2021-45555/index.md","name":"CVE-2021-45555","record":{"aliases":["GHSA-v7vj-6p6j-g2gf"],"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":"high_privilege","summary":"Authenticated attackers can execute arbitrary commands on NETGEAR routers via a command injection vulnerability.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"r7900p_firmware","vendor":"netgear"},{"product":"r7960p_firmware","vendor":"netgear"},{"product":"r8000p_firmware","vendor":"netgear"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AC:L/AV:A/A:H/C:H/I:H/PR:H/S:C/UI:N","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Certain NETGEAR devices are affected by command injection by an authenticated user.
