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-2019-20756 and fix it if it is affected.\n\nWhat it is: CVE-2019-20756 is a high-severity cross-site scripting vulnerability in Netgear Ex6200 Firmware, published on 16 Apr 2020. 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-2019-20756 in the wild and no public exploit code.\n\nAffected product: Netgear Ex6200 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-2019-20756/ (Markdown: https://insights.sbomify.com/CVE-2019-20756/index.md)","id":"CVE-2019-20756","markdown":"https://insights.sbomify.com/CVE-2019-20756/index.md","name":"CVE-2019-20756","record":{"aliases":["GHSA-cmvh-xx7q-427v"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"none","summary":"Reflected XSS in NETGEAR routers allows attackers to execute scripts in user browsers, potentially leading to session hijacking or data theft.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ex3700_firmware","vendor":"netgear"},{"product":"ex3800_firmware","vendor":"netgear"},{"product":"ex6000_firmware","vendor":"netgear"},{"product":"ex6100_firmware","vendor":"netgear"},{"product":"ex6120_firmware","vendor":"netgear"},{"product":"ex6130_firmware","vendor":"netgear"},{"product":"ex6150_firmware","vendor":"netgear"},{"product":"ex6200_firmware","vendor":"netgear"},{"product":"ex7000_firmware","vendor":"netgear"},{"product":"r6300_firmware","vendor":"netgear"},{"product":"r6400_firmware","vendor":"netgear"},{"product":"r6900p_firmware","vendor":"netgear"},{"product":"r7000p_firmware","vendor":"netgear"},{"product":"r7300dst_firmware","vendor":"netgear"},{"product":"r8300_firmware","vendor":"netgear"},{"product":"r8500_firmware","vendor":"netgear"},{"product":"wn2500rp_firmware","vendor":"netgear"},{"product":"wndr3400_firmware","vendor":"netgear"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AC:L/AV:A/A:N/C:H/I:L/PR:N/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Certain NETGEAR devices are affected by reflected XSS.
