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-2023-6397 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-2023-6397/ (Markdown: https://insights.sbomify.com/CVE-2023-6397/index.md)","id":"CVE-2023-6397","markdown":"https://insights.sbomify.com/CVE-2023-6397/index.md","name":"CVE-2023-6397","record":{"aliases":["GHSA-wj52-rfj4-xjcm"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Zyxel firewall firmware","requires_auth":"none","summary":"A LAN-based attacker can cause denial-of-service on Zyxel firewalls by triggering a null pointer dereference via a crafted RAR file when Anti-Malware is enabled.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"atp100_firmware","vendor":"zyxel"},{"product":"atp100w_firmware","vendor":"zyxel"},{"product":"atp200_firmware","vendor":"zyxel"},{"product":"atp500_firmware","vendor":"zyxel"},{"product":"atp700_firmware","vendor":"zyxel"},{"product":"atp800_firmware","vendor":"zyxel"},{"product":"usg_flex_100_firmware","vendor":"zyxel"},{"product":"usg_flex_100ax_firmware","vendor":"zyxel"},{"product":"usg_flex_100h_firmware","vendor":"zyxel"},{"product":"usg_flex_100w_firmware","vendor":"zyxel"},{"product":"usg_flex_200_firmware","vendor":"zyxel"},{"product":"usg_flex_200h_firmware","vendor":"zyxel"},{"product":"usg_flex_200hp_firmware","vendor":"zyxel"},{"product":"usg_flex_500_firmware","vendor":"zyxel"},{"product":"usg_flex_500h_firmware","vendor":"zyxel"},{"product":"usg_flex_50_firmware","vendor":"zyxel"},{"product":"usg_flex_50w_firmware","vendor":"zyxel"},{"product":"usg_flex_700_firmware","vendor":"zyxel"},{"product":"usg_flex_700h_firmware","vendor":"zyxel"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A null pointer dereference vulnerability in Zyxel ATP series firmware versions from 4.32 through 5.37 Patch 1 and USG FLEX series firmware versions from 4.50 through 5.37 Patch 1 could allow a LAN-based attacker to cause denial-of-service (DoS) conditions by downloading a crafted RAR compressed file onto a LAN-side host if the firewall has the “Anti-Malware” feature enabled.","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":"Null dereference in ATP series firmware","id":"CVE-2023-6397","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in NWA50AX firmware","id":"CVE-2023-6398"},"packages":[],"prev":{"headline":"Mock: privilege escalation for users that can access mock configuration","id":"CVE-2023-6395"},"products":["ATP series firmware","USG FLEX series firmware"],"published":"2024-02-20","related":[{"cvss_score":9.8,"headline":"Zyxel Multiple Firewalls Buffer Overflow","id":"CVE-2023-33009","kev_date_added":"2023-06-05","published":"2023-05-24"},{"cvss_score":9.8,"headline":"Zyxel Multiple Firewalls Buffer Overflow","id":"CVE-2023-33010","kev_date_added":"2023-06-05","published":"2023-05-24"},{"cvss_score":9.8,"headline":"Zyxel Multiple Firewalls OS Command Injection","id":"CVE-2023-28771","kev_date_added":"2023-05-31","published":"2023-04-25"},{"cvss_score":9.8,"headline":"Zyxel Multiple Firewalls OS Command Injection","id":"CVE-2022-30525","kev_date_added":"2022-05-16","published":"2022-05-12"},{"cvss_score":9.8,"headline":"Zyxel Multiple Products Use of Hard-Coded Credentials","id":"CVE-2020-29583","kev_date_added":"2021-11-03","published":"2020-12-22"},{"cvss_score":9.8,"headline":"Zyxel Multiple NAS Devices OS Command Injection","id":"CVE-2020-9054","kev_date_added":"2022-03-25","published":"2020-03-04"},{"cvss_score":9.8,"headline":"Auth bypass in ATP series firmware","id":"CVE-2022-0342","kev_date_added":null,"published":"2022-03-28"}],"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":"2024-08-02","vendors":["Zyxel"]},"summary":"A LAN-based attacker can cause denial-of-service on Zyxel firewalls by triggering a null pointer dereference via a crafted RAR file when Anti-Malware is enabled.","url":"https://insights.sbomify.com/CVE-2023-6397/"}
