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-2022-4873 in the wild and no public exploit code.\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-2022-4873/ (Markdown: https://insights.sbomify.com/CVE-2022-4873/index.md)","id":"CVE-2022-4873","markdown":"https://insights.sbomify.com/CVE-2022-4873/index.md","name":"CVE-2022-4873","record":{"aliases":["GHSA-5fm2-88hc-cx64"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcomm router","requires_auth":"none","summary":"A stack-based buffer overflow in Netcomm routers allows attackers to crash the application by overwriting the instruction pointer via the sessionKey parameter.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":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":"On Netcomm router models NF20MESH, NF20, and NL1902 a stack based buffer overflow affects the sessionKey parameter.
