Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-20173 and fix it if it is affected.\n\nWhat it is: CVE-2021-20173 is a high-severity command injection vulnerability in Netgear R6700 Firmware, published on 30 Dec 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20173 in the wild and no public exploit code.\n\nAffected product: Netgear R6700 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-2021-20173/ (Markdown: https://insights.sbomify.com/CVE-2021-20173/index.md)","id":"CVE-2021-20173","markdown":"https://insights.sbomify.com/CVE-2021-20173/index.md","name":"CVE-2021-20173","record":{"aliases":["GHSA-x3v5-8924-rm83"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Netgear Nighthawk router","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary commands on Netgear Nighthawk R6700 routers by exploiting a command injection flaw in the update functionality via the SOAP interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"r6700_firmware","vendor":"netgear"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Netgear Nighthawk R6700 version 1.0.4.120 contains a command injection vulnerability in update functionality of the device.
