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-2016-4577 in the wild and no public exploit code.\n\nAffected product: Huawei Ngfw Module 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-2016-4577/ (Markdown: https://insights.sbomify.com/CVE-2016-4577/index.md)","id":"CVE-2016-4577","markdown":"https://insights.sbomify.com/CVE-2016-4577/index.md","name":"CVE-2016-4577","record":{"aliases":["GHSA-v5q4-qq7p-9vw8"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Huawei firewall","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via crafted packets exploiting a buffer overflow in Huawei firewalls.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ngfw_module_firmware","vendor":"huawei"},{"product":"secospace_usg6300_firmware","vendor":"huawei"},{"product":"secospace_usg6500_firmware","vendor":"huawei"},{"product":"secospace_usg6600_firmware","vendor":"huawei"},{"product":"usg9500_firmware","vendor":"huawei"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in the Smart DNS functionality in the Huawei NGFW Module and Secospace USG6300, USG6500, USG6600, and USG9500 firewalls with software before V500R001C20SPC100 allows remote attackers to cause a denial of service or execute arbitrary code via a crafted packet, related to \"illegitimate parameters.\"","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2016-4577","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"huawei:ngfw_module_firmware","products":["huawei:ngfw_module_firmware","huawei:secospace_usg6300_firmware","huawei:secospace_usg6500_firmware","huawei:secospace_usg6600_firmware","huawei:usg9500_firmware"],"type":"memory_corruption","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2016-4578"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2016-4576"},"products":["n/a"],"published":"2016-05-23","related":[{"cvss_score":7.5,"headline":"Denial of service in NGFW Module;NIP6300;NIP6600;NIP6800;Secospace USG6300;Secospace USG6500;Secospace USG6600;USG9500","id":"CVE-2020-9213","kev_date_added":null,"published":"2021-03-22"},{"cvss_score":7.5,"headline":"Information disclosure in NGFW Module, NIP6300, NIP6600, Secospace USG6500, Secospace USG6600, USG9500","id":"CVE-2020-1856","kev_date_added":null,"published":"2020-02-17"},{"cvss_score":6.5,"headline":"Memory corruption in NGFW Module;Secospace USG6300;Secospace USG6500;Secospace USG6600;USG9500","id":"CVE-2021-22411","kev_date_added":null,"published":"2021-05-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or cause denial of service via crafted packets exploiting a buffer overflow in Huawei firewalls.","url":"https://insights.sbomify.com/CVE-2016-4577/"}
