An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-4967 in the wild and no public exploit code.\n\nAffected product: Cloud Software Group NetScaler ADC. 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-2023-4967/ (Markdown: https://insights.sbomify.com/CVE-2023-4967/index.md)","id":"CVE-2023-4967","markdown":"https://insights.sbomify.com/CVE-2023-4967/index.md","name":"CVE-2023-4967","record":{"aliases":["GHSA-wj66-97v8-j738"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"NetScaler ADC Gateway","requires_auth":"none","summary":"Attackers can cause denial of service in NetScaler ADC and Gateway when configured as a Gateway or AAA Virtual Server.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Citrix","cpe":[{"product":"netscaler_application_delivery_controller","vendor":"citrix"},{"product":"netscaler_gateway","vendor":"citrix"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Denial of Service in NetScaler ADC and NetScaler Gateway when configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA Virtual Server","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","id":"CVE-2023-4967","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":"WPLegalPages \u003c= 2.9.2 - Authenticated (Author+) Stored Cross-Site Scripting via Shortcode","id":"CVE-2023-4968"},"packages":[],"prev":{"headline":"Citrix NetScaler ADC and NetScaler Gateway Buffer Overflow","id":"CVE-2023-4966"},"products":["NetScaler ADC","NetScaler Gateway"],"published":"2023-10-27","related":[{"cvss_score":9.8,"headline":"Citrix NetScaler ADC and NetScaler Gateway Code Injection","id":"CVE-2023-3519","kev_date_added":"2023-07-19","published":"2023-07-19"},{"cvss_score":9.5,"headline":"Citrix NetScaler Improper Input Validation","id":"CVE-2026-88771","kev_date_added":"2026-09-27","published":"2026-09-27"},{"cvss_score":9.5,"headline":"Citrix NetScaler Improper Restriction of Operations within the Bounds of a Memory Buffer","id":"CVE-2026-88772","kev_date_added":"2026-09-27","published":"2026-09-27"},{"cvss_score":9.4,"headline":"Citrix NetScaler ADC and NetScaler Gateway Buffer Overflow","id":"CVE-2023-4966","kev_date_added":"2023-10-18","published":"2023-10-10"},{"cvss_score":9.3,"headline":"Citrix NetScaler Authentication Bypass Using an Alternate Path or Channel","id":"CVE-2026-19490","kev_date_added":"2026-09-09","published":"2026-08-19"},{"cvss_score":9.3,"headline":"Citrix NetScaler Out-of-Bounds Read","id":"CVE-2026-3055","kev_date_added":"2026-03-30","published":"2026-03-23"},{"cvss_score":9.3,"headline":"Citrix NetScaler ADC and Gateway Out-of-Bounds Read","id":"CVE-2025-5777","kev_date_added":"2025-07-10","published":"2025-06-17"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-27","vendors":["Cloud Software Group"]},"summary":"Attackers can cause denial of service in NetScaler ADC and Gateway when configured as a Gateway or AAA Virtual Server.","url":"https://insights.sbomify.com/CVE-2023-4967/"}
