It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-40251 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-2023-40251/ (Markdown: https://insights.sbomify.com/CVE-2023-40251/index.md)","id":"CVE-2023-40251","markdown":"https://insights.sbomify.com/CVE-2023-40251/index.md","name":"CVE-2023-40251","record":{"aliases":["GHSA-55c4-h5wf-fc47"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Network Access Control","requires_auth":"low_privilege","summary":"Attackers can intercept sensitive data via Man-in-the-Middle attacks due to missing encryption in Genian NAC and ZTNA products.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"genian_nac","vendor":"genians"},{"product":"genian_ztna","vendor":"genians"}],"cvss":{"score":5.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-311","name":"Missing Encryption of Sensitive Data"}],"description":"Missing Encryption of Sensitive Data vulnerability in Genians Genian NAC V4.0, Genians Genian NAC V5.0, Genians Genian NAC Suite V5.0, Genians Genian ZTNA allows Man in the Middle Attack.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":"Weak cryptography in Genian NAC Suite V5.0","id":"CVE-2023-40251","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in Genian NAC Suite V5.0","id":"CVE-2023-40252"},"packages":[],"prev":{"headline":"Memory corruption in HCell","id":"CVE-2023-40250"},"products":["Genian NAC Suite V5.0","Genian NAC V4.0","Genian NAC V5.0","Genian ZTNA"],"published":"2023-08-17","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":6,"headline":"Auth bypass in Genian NAC Suite V5.0","id":"CVE-2023-40253","kev_date_added":null,"published":"2023-08-11"}],"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 intercept sensitive data via Man-in-the-Middle attacks due to missing encryption in Genian NAC and ZTNA products.","url":"https://insights.sbomify.com/CVE-2023-40251/"}
