An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-28800 in the wild and no public exploit code.\n\nAffected product: Zscaler Client Connector. 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-2023-28800/ (Markdown: https://insights.sbomify.com/CVE-2023-28800/index.md)","id":"CVE-2023-28800","markdown":"https://insights.sbomify.com/CVE-2023-28800/index.md","name":"CVE-2023-28800","record":{"aliases":["GHSA-crh5-rq78-8m4h"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Zscaler Client Connector","requires_auth":"none","summary":"Attackers can execute XSS via the redirect URL parameter in the admin login interface, potentially compromising administrator accounts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zscaler","cpe":[{"product":"client_connector","vendor":"zscaler"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"When using local accounts for administration, the redirect url parameter was not encoded correctly, allowing for an XSS attack providing admin login.","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":"Output encoding missing in redrurl parameter","id":"CVE-2023-28800","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":6,"next":{"headline":"Improper SAML signature verification","id":"CVE-2023-28801"},"packages":[],"prev":{"headline":"Open redirect in Client Connector","id":"CVE-2023-28799"},"products":["Client Connector"],"published":"2023-06-22","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-11633","kev_date_added":null,"published":"2021-07-15"},{"cvss_score":8.8,"headline":"Anti-Tampering bypass via Repair App functionality","id":"CVE-2024-23463","kev_date_added":null,"published":"2024-04-30"},{"cvss_score":8.2,"headline":"Linux ZCC allows unsigned updates, allowing elevated Code Execution","id":"CVE-2023-28804","kev_date_added":null,"published":"2023-10-23"},{"cvss_score":8.2,"headline":"Open redirect in Client Connector","id":"CVE-2023-28799","kev_date_added":null,"published":"2023-06-22"},{"cvss_score":7.8,"headline":"Signature validation issue leads to Anti-Tampering bypass","id":"CVE-2024-23456","kev_date_added":null,"published":"2024-08-06"},{"cvss_score":7.8,"headline":"Anti-tampering can be disabled with uninstall password enforced","id":"CVE-2024-23457","kev_date_added":null,"published":"2024-05-01"}],"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":"total"},"state":"PUBLISHED","updated":"2024-12-06","vendors":["Zscaler"]},"summary":"Attackers can execute XSS via the redirect URL parameter in the admin login interface, potentially compromising administrator accounts.","url":"https://insights.sbomify.com/CVE-2023-28800/"}
