It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-28768 and fix it if it is affected.\n\nWhat it is: CVE-2023-28768 is a medium-severity denial of service vulnerability in Zyxel XGS2220-30 firmware, published on 14 Aug 2023. 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-2023-28768 in the wild and no public exploit code.\n\nAffected product: Zyxel XGS2220-30 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-2023-28768/ (Markdown: https://insights.sbomify.com/CVE-2023-28768/index.md)","id":"CVE-2023-28768","markdown":"https://insights.sbomify.com/CVE-2023-28768/index.md","name":"CVE-2023-28768","record":{"aliases":["GHSA-7vjf-qw8c-2v29"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel network switch","requires_auth":"none","summary":"An unauthenticated LAN attacker can cause denial of service on Zyxel switches by sending crafted frames due to improper frame handling.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"xgs2220-30_firmware","vendor":"zyxel"},{"product":"xgs2220-30f_firmware","vendor":"zyxel"},{"product":"xgs2220-30hp_firmware","vendor":"zyxel"},{"product":"xgs2220-54_firmware","vendor":"zyxel"},{"product":"xgs2220-54fp_firmware","vendor":"zyxel"},{"product":"xgs2220-54hp_firmware","vendor":"zyxel"},{"product":"xmg1930-30_firmware","vendor":"zyxel"},{"product":"xmg1930-30hp_firmware","vendor":"zyxel"},{"product":"xs1930-10_firmware","vendor":"zyxel"},{"product":"xs1930-12f_firmware","vendor":"zyxel"},{"product":"xs1930-12hp_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-755","name":"Improper Handling of Exceptional Conditions"}],"description":"Improper frame handling in the Zyxel XGS2220-30 firmware version V4.80(ABXN.1), XMG1930-30 firmware version V4.80(ACAR.1), and XS1930-10 firmware version V4.80(ABQE.1) could allow an unauthenticated LAN-based attacker to cause denial-of-service (DoS) conditions by sending crafted frames to an affected switch.","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":"Denial of service in XGS2220-30 firmware","id":"CVE-2023-28768","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in DX5401-B0 firmware","id":"CVE-2023-28769"},"packages":[],"prev":{"headline":"Command injection in ATP series firmware","id":"CVE-2023-28767"},"products":["XGS2220-30 firmware","XMG1930-30 firmware","XS1930-10 firmware"],"published":"2023-08-14","related":[],"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":"2024-10-01","vendors":["Zyxel"]},"summary":"An unauthenticated LAN attacker can cause denial of service on Zyxel switches by sending crafted frames due to improper frame handling.","url":"https://insights.sbomify.com/CVE-2023-28768/"}
