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-2023-5593 and fix it if it is affected.\n\nWhat it is: CVE-2023-5593 is a high-severity memory corruption vulnerability in Zyxel SecuExtender SSL VPN Client, published on 20 Nov 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-2023-5593 in the wild and no public exploit code.\n\nAffected product: Zyxel SecuExtender SSL VPN Client. 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-2023-5593/ (Markdown: https://insights.sbomify.com/CVE-2023-5593/index.md)","id":"CVE-2023-5593","markdown":"https://insights.sbomify.com/CVE-2023-5593/index.md","name":"CVE-2023-5593","record":{"aliases":["GHSA-85wf-77c7-2h37"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SSL VPN Client","requires_auth":"low_privilege","summary":"An authenticated local user can escalate privileges via an out-of-bounds write in the Zyxel SecuExtender SSL VPN Client.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"secuextender_ssl_vpn","vendor":"zyxel"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The out-of-bounds write vulnerability in the Windows-based SecuExtender SSL VPN Client software version 4.0.4.0 could allow an authenticated local user to gain a privilege escalation by sending a crafted CREATE message.","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 SecuExtender SSL VPN Client","id":"CVE-2023-5593","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Improper following of a certificate's chain of trust in ESET security products","id":"CVE-2023-5594"},"packages":[],"prev":{"headline":"Phoenix Contact: ProConOs prone to Download of Code Without Integrity Check","id":"CVE-2023-5592"},"products":["SecuExtender SSL VPN Client"],"published":"2023-11-20","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":"total"},"state":"PUBLISHED","updated":"2024-08-29","vendors":["Zyxel"]},"summary":"An authenticated local user can escalate privileges via an out-of-bounds write in the Zyxel SecuExtender SSL VPN Client.","url":"https://insights.sbomify.com/CVE-2023-5593/"}
