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-2023-40253 in the wild and no public exploit code.\n\nAffected product: Genians Genian NAC Suite V5.0. 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-2023-40253/ (Markdown: https://insights.sbomify.com/CVE-2023-40253/index.md)","id":"CVE-2023-40253","markdown":"https://insights.sbomify.com/CVE-2023-40253/index.md","name":"CVE-2023-40253","record":{"aliases":["GHSA-vjw2-5fjm-hhr4"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Genian NAC","requires_auth":"high_privilege","summary":"Attackers can bypass authentication in Genian NAC and ZTNA products, potentially gaining unauthorized access to network control systems.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"genian_nac","vendor":"genians"},{"product":"genian_ztna","vendor":"genians"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Improper Authentication vulnerability in Genians Genian NAC V4.0, Genians Genian NAC V5.0, Genians Genian NAC Suite V5.0, Genians Genian ZTNA allows Authentication Abuse.This issue affects Genian NAC V4.0: from V4.0.0 through V4.0.155; Genian NAC V5.0: from V5.0.0 through V5.0.42 (Revision 117460); Genian NAC Suite V5.0: from V5.0.0 through V5.0.54; Genian ZTNA: from V6.0.0 through V6.0.15.","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":"Auth bypass in Genian NAC Suite V5.0","id":"CVE-2023-40253","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Supply chain in Genian NAC Suite V5.0","id":"CVE-2023-40254"},"packages":[],"prev":{"headline":"Code injection in Genian NAC Suite V5.0","id":"CVE-2023-40252"},"products":["Genian NAC Suite V5.0","Genian NAC V4.0","Genian NAC V5.0","Genian ZTNA"],"published":"2023-08-11","related":[{"cvss_score":9.6,"headline":"Genian NAC remote code execution vulnerability","id":"CVE-2021-26622","kev_date_added":null,"published":"2022-03-25"},{"cvss_score":7.5,"headline":"Supply chain in Genian NAC Suite V5.0","id":"CVE-2023-40254","kev_date_added":null,"published":"2023-08-11"},{"cvss_score":6,"headline":"Code injection in Genian NAC Suite V5.0","id":"CVE-2023-40252","kev_date_added":null,"published":"2023-08-17"},{"cvss_score":5.2,"headline":"Weak cryptography in Genian NAC Suite V5.0","id":"CVE-2023-40251","kev_date_added":null,"published":"2023-08-17"}],"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":["Genians"]},"summary":"Attackers can bypass authentication in Genian NAC and ZTNA products, potentially gaining unauthorized access to network control systems.","url":"https://insights.sbomify.com/CVE-2023-40253/"}
