An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2022-27518 in the wild since at least 13 Dec 2022.\n\nAffected product: Citrix Gateway, Citrix 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-2022-27518/ (Markdown: https://insights.sbomify.com/CVE-2022-27518/index.md)","id":"CVE-2022-27518","markdown":"https://insights.sbomify.com/CVE-2022-27518/index.md","name":"CVE-2022-27518","record":{"aliases":["GHSA-w8vh-3g88-rg95"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Citrix ADC Gateway","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code remotely on Citrix ADC and Gateway devices, requiring immediate patching.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Citrix","cpe":[{"product":"application_delivery_controller_firmware","vendor":"citrix"},{"product":"gateway_firmware","vendor":"citrix"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-664","name":"Improper Control of a Resource Through its Lifetime"}],"description":"Unauthenticated remote arbitrary code execution","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-01-17","github_poc":1,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-01-17T19:40:04Z","kind":"github_poc","ref":"https://github.com/dolby360/CVE-2022-27518_POC","stars":2,"title":"A POC on how to exploit CVE-2022-27518 "}],"tier":"exploited"},"has_fix":null,"headline":"Citrix Application Delivery Controller (ADC) and Gateway Authentication Bypass","id":"CVE-2022-27518","indexable":true,"kev":{"dateAdded":"2022-12-13","dueDate":"2023-01-03","knownRansomwareCampaignUse":"Unknown","product":"Application Delivery Controller (ADC) and Gateway","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Citrix","vulnerabilityName":"Citrix Application Delivery Controller (ADC) and Gateway Authentication Bypass Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Autodesk Trueview","id":"CVE-2022-27523"},"packages":[],"prev":{"headline":"User login brute force protection functionality bypass","id":"CVE-2022-27516"},"products":["Citrix Gateway, Citrix ADC"],"published":"2022-12-13","related":[{"cvss_score":9.8,"headline":"Citrix ADC, Gateway, and SD-WAN WANOP Appliance Code Execution","id":"CVE-2019-19781","kev_date_added":"2021-11-03","published":"2019-12-27"},{"cvss_score":6.5,"headline":"Citrix ADC, Gateway, and SD-WAN WANOP Appliance Authorization Bypass","id":"CVE-2020-8193","kev_date_added":"2021-11-03","published":"2020-07-10"},{"cvss_score":6.5,"headline":"Citrix ADC, Gateway, and SD-WAN WANOP Appliance Information Disclosure","id":"CVE-2020-8195","kev_date_added":"2021-11-03","published":"2020-07-10"},{"cvss_score":4.3,"headline":"Citrix ADC, Gateway, and SD-WAN WANOP Appliance Information Disclosure","id":"CVE-2020-8196","kev_date_added":"2021-11-03","published":"2020-07-10"},{"cvss_score":9.8,"headline":"Unauthorized access to Gateway user capabilities","id":"CVE-2022-27510","kev_date_added":null,"published":"2022-11-08"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2019-18225","kev_date_added":null,"published":"2019-10-21"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Citrix"]},"summary":"Unauthenticated attackers can execute arbitrary code remotely on Citrix ADC and Gateway devices, requiring immediate patching.","url":"https://insights.sbomify.com/CVE-2022-27518/"}
