An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-8191 exists.\n\nAffected product: Citrix ADC, Citrix Gateway, Citrix SDWAN WAN-OP. 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-2020-8191/ (Markdown: https://insights.sbomify.com/CVE-2020-8191/index.md)","id":"CVE-2020-8191","markdown":"https://insights.sbomify.com/CVE-2020-8191/index.md","name":"CVE-2020-8191","record":{"aliases":["GHSA-h686-q2xf-663f"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Citrix ADC Gateway","requires_auth":"none","summary":"Reflected Cross-Site Scripting in Citrix ADC and Gateway allows attackers to execute scripts in user sessions, requiring an upgrade to secure versions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"application_delivery_controller_firmware","vendor":"citrix"},{"product":"gateway_firmware","vendor":"citrix"},{"product":"netscaler_gateway_firmware","vendor":"citrix"},{"product":"sd-wan_wanop","vendor":"citrix"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper input validation in Citrix ADC and Citrix Gateway versions before 13.0-58.30, 12.1-57.18, 12.0-63.21, 11.1-64.14 and 10.5-70.18 and Citrix SDWAN WAN-OP versions before 11.1.1a, 11.0.3d and 10.2.7 allows reflected Cross Site Scripting (XSS).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-8191.yaml","stars":null,"title":"Citrix ADC/Gateway - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in Citrix ADC, Citrix Gateway, Citrix SDWAN WAN-OP","id":"CVE-2020-8191","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in fastify","id":"CVE-2020-8192"},"packages":[],"prev":{"headline":"Privilege escalation in Citrix ADC, Citrix Gateway","id":"CVE-2020-8190"},"products":["Citrix ADC, Citrix Gateway, Citrix SDWAN WAN-OP"],"published":"2020-07-10","related":[{"cvss_score":9.8,"headline":"Citrix Application Delivery Controller (ADC) and Gateway Authentication Bypass","id":"CVE-2022-27518","kev_date_added":"2022-12-13","published":"2022-12-13"},{"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Reflected Cross-Site Scripting in Citrix ADC and Gateway allows attackers to execute scripts in user sessions, requiring an upgrade to secure versions.","url":"https://insights.sbomify.com/CVE-2020-8191/"}
