Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-51743 in the wild and no public exploit code.\n\nAffected product: Hathway Skyworth Router CM5100. 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-2023-51743/ (Markdown: https://insights.sbomify.com/CVE-2023-51743/index.md)","id":"CVE-2023-51743","markdown":"https://insights.sbomify.com/CVE-2023-51743/index.md","name":"CVE-2023-51743","record":{"aliases":["GHSA-6f66-xj9j-jjg9"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Skyworth Router","requires_auth":"low_privilege","summary":"A remote attacker can cause a Denial of Service on Skyworth Routers by sending crafted input to the UCID parameter.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-In","cpe":[{"product":"cm5100_firmware","vendor":"skyworthdigital"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"This vulnerability exist in Skyworth Router CM5100, version 4.1.1.24, due to insufficient validation of user supplied input for the Set Upstream Channel ID (UCID) parameter at its web interface.
