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-2019-5256 in the wild and no public exploit code.\n\nAffected product: Huawei Nip6300 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-2019-5256/ (Markdown: https://insights.sbomify.com/CVE-2019-5256/index.md)","id":"CVE-2019-5256","markdown":"https://insights.sbomify.com/CVE-2019-5256/index.md","name":"CVE-2019-5256","record":{"aliases":["GHSA-9x6m-qh7h-v267"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Huawei network security devices","requires_auth":"low_privilege","summary":"A local attacker can cause a denial of service and process reboot on various Huawei network security devices by sending crafted parameters that trigger a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"ap2000_firmware","vendor":"huawei"},{"product":"espace_u1981_firmware","vendor":"huawei"},{"product":"ips_firmware","vendor":"huawei"},{"product":"ngfw_firmware","vendor":"huawei"},{"product":"nip6300_firmware","vendor":"huawei"},{"product":"nip6600_firmware","vendor":"huawei"},{"product":"nip6800_firmware","vendor":"huawei"},{"product":"s5700_firmware","vendor":"huawei"},{"product":"secospace_antiddos8000_firmware","vendor":"huawei"},{"product":"secospace_usg6300_firmware","vendor":"huawei"},{"product":"secospace_usg6500_firmware","vendor":"huawei"},{"product":"secospace_usg6600_firmware","vendor":"huawei"},{"product":"semg9811_firmware","vendor":"huawei"},{"product":"svn5600_firmware","vendor":"huawei"},{"product":"svn5800-c_firmware","vendor":"huawei"},{"product":"svn5800_firmware","vendor":"huawei"},{"product":"usg6000v_firmware","vendor":"huawei"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Certain Huawei products (AP2000;IPS Module;NGFW Module;NIP6300;NIP6600;NIP6800;S5700;SVN5600;SVN5800;SVN5800-C;SeMG9811;Secospace AntiDDoS8000;Secospace USG6300;Secospace USG6500;Secospace USG6600;USG6000V;eSpace U1981) have a null pointer dereference vulnerability.
