An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-6343 in the wild and no public exploit code.\n\nAffected product: Zyxel ATP series 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-2024-6343/ (Markdown: https://insights.sbomify.com/CVE-2024-6343/index.md)","id":"CVE-2024-6343","markdown":"https://insights.sbomify.com/CVE-2024-6343/index.md","name":"CVE-2024-6343","record":{"aliases":["GHSA-49fx-5cmv-3mw7"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel firewall firmware","requires_auth":"high_privilege","summary":"An authenticated administrator can cause a denial of service on Zyxel firewalls by sending a crafted HTTP request that triggers a buffer overflow.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"zld","vendor":"zyxel"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability in the CGI program of Zyxel ATP series firmware versions from V4.32 through V5.38, USG FLEX series firmware versions from V4.50 through V5.38, USG FLEX 50(W) series firmware versions from V4.16 through V5.38, and USG20(W)-VPN series firmware versions from V4.16 through V5.38 could allow an authenticated attacker with administrator privileges to cause denial of service (DoS) conditions by sending a crafted HTTP request to a vulnerable device.","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 ATP series firmware","id":"CVE-2024-6343","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"ZKTeco ZKBio CVSecurity V5000 Push Configuration Section cross site scripting","id":"CVE-2024-6344"},"packages":[],"prev":{"headline":"Command injection in NAS326 firmware","id":"CVE-2024-6342"},"products":["ATP series firmware","USG FLEX 50(W) series firmware","USG FLEX series firmware","USG20(W)-VPN series firmware"],"published":"2024-09-03","related":[{"cvss_score":7.5,"headline":"Zyxel Multiple Firewalls Path Traversal","id":"CVE-2024-11667","kev_date_added":"2024-12-03","published":"2024-11-27"},{"cvss_score":8.1,"headline":"Missing authorization in ATP series firmware","id":"CVE-2025-9133","kev_date_added":null,"published":"2025-10-21"},{"cvss_score":8.1,"headline":"Command injection in ATP series firmware","id":"CVE-2024-42057","kev_date_added":null,"published":"2024-09-03"},{"cvss_score":7.5,"headline":"Null dereference in ATP series firmware","id":"CVE-2024-42058","kev_date_added":null,"published":"2024-09-03"},{"cvss_score":7.5,"headline":"Integer overflow in ATP series firmware","id":"CVE-2023-4398","kev_date_added":null,"published":"2023-11-28"},{"cvss_score":7.2,"headline":"Command injection in ATP series firmware","id":"CVE-2025-8078","kev_date_added":null,"published":"2025-10-21"},{"cvss_score":7.2,"headline":"Command injection in ATP series firmware","id":"CVE-2024-42059","kev_date_added":null,"published":"2024-09-03"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-03","vendors":["Zyxel"]},"summary":"An authenticated administrator can cause a denial of service on Zyxel firewalls by sending a crafted HTTP request that triggers a buffer overflow.","url":"https://insights.sbomify.com/CVE-2024-6343/"}
