Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-28801 in the wild and no public exploit code.\n\nAffected product: Zscaler ZIA Admin Portal. 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-2023-28801/ (Markdown: https://insights.sbomify.com/CVE-2023-28801/index.md)","id":"CVE-2023-28801","markdown":"https://insights.sbomify.com/CVE-2023-28801/index.md","name":"CVE-2023-28801","record":{"aliases":["GHSA-wfp5-6m78-crh3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Zscaler Admin Portal","requires_auth":"low_privilege","summary":"Attackers can escalate privileges by bypassing SAML signature verification in the Zscaler Admin UI.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zscaler","cpe":[{"product":"zscaler_internet_access_admin_portal","vendor":"zscaler"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"An Improper Verification of Cryptographic Signature in the SAML authentication of the Zscaler Admin UI allows a Privilege Escalation.This issue affects Admin UI: from 6.2 before 6.2r.","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":"Improper SAML signature verification","id":"CVE-2023-28801","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Disable Zscaler using machine tunnel restart","id":"CVE-2023-28802"},"packages":[],"prev":{"headline":"Output encoding missing in redrurl parameter","id":"CVE-2023-28800"},"products":["ZIA Admin Portal"],"published":"2023-08-31","related":[{"cvss_score":7.6,"headline":"ZIA Admin UI Input Validation Bug","id":"CVE-2026-22567","kev_date_added":null,"published":"2026-02-23"},{"cvss_score":5.5,"headline":"Unauthorized information retrieval in ZIA Admin UI","id":"CVE-2026-22568","kev_date_added":null,"published":"2026-02-23"}],"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":"2024-10-01","vendors":["Zscaler"]},"summary":"Attackers can escalate privileges by bypassing SAML signature verification in the Zscaler Admin UI.","url":"https://insights.sbomify.com/CVE-2023-28801/"}
