An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-4874 exists.\n\nAffected product: Netcomm NF20. 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-2022-4874/ (Markdown: https://insights.sbomify.com/CVE-2022-4874/index.md)","id":"CVE-2022-4874","markdown":"https://insights.sbomify.com/CVE-2022-4874/index.md","name":"CVE-2022-4874","record":{"aliases":["GHSA-6pwv-hr7p-g77v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcomm router","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication on Netcomm routers to access static content due to flawed session handling logic.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"nf20_firmware","vendor":"netcommwireless"},{"product":"nf20mesh_firmware","vendor":"netcommwireless"},{"product":"nl1902_firmware","vendor":"netcommwireless"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Authentication bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows an unauthenticated user to access content.
