An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-37235 in the wild and no public exploit code.\n\nAffected product: Netgear R7000 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-2022-37235/ (Markdown: https://insights.sbomify.com/CVE-2022-37235/index.md)","id":"CVE-2022-37235","markdown":"https://insights.sbomify.com/CVE-2022-37235/index.md","name":"CVE-2022-37235","record":{"aliases":["GHSA-x2rq-mrc8-r79h"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Netgear WiFi router","requires_auth":"none","summary":"A stack buffer overflow in the wl binary allows attackers to execute arbitrary code on Netgear Nighthawk routers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"r7000_firmware","vendor":"netgear"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Netgear Nighthawk AC1900 Smart WiFi Dual Band Gigabit Router R7000-V1.0.11.134_10.2.119 is vulnerable to Buffer Overflow via the wl binary in firmware.
