It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-28807 in the wild and no public exploit code.\n\nAffected product: Zscaler ZIA. 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-2023-28807/ (Markdown: https://insights.sbomify.com/CVE-2023-28807/index.md)","id":"CVE-2023-28807","markdown":"https://insights.sbomify.com/CVE-2023-28807/index.md","name":"CVE-2023-28807","record":{"aliases":["GHSA-p774-6cp5-x7cj"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zscaler Internet Access","requires_auth":"none","summary":"Attackers can bypass Zscaler Internet Access security controls by mismatching Connect Host and SNI to hide malicious traffic.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zscaler","cpe":[{"product":"secure_internet_and_saas_access","vendor":"zscaler"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"In Zscaler Internet Access (ZIA) a mismatch between Connect Host and Client Hello's Server Name Indication (SNI) enables attackers to evade network security controls by hiding their communications within legitimate traffic.","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":"Bypass of ZIA domain fronting detection module through evasion technique","id":"CVE-2023-28807","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in DS-A71024/48/72R,DS-A80624S,DS-A81016S,DS-A72024/72R,DS-A80316S,DS-A82024D","id":"CVE-2023-28808"},"packages":[],"prev":{"headline":"Signature validation error in DLL allows disabling anti-tampering protection","id":"CVE-2023-28806"},"products":["ZIA"],"published":"2024-01-31","related":[],"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":"partial"},"state":"PUBLISHED","updated":"2025-06-17","vendors":["Zscaler"]},"summary":"Attackers can bypass Zscaler Internet Access security controls by mismatching Connect Host and SNI to hide malicious traffic.","url":"https://insights.sbomify.com/CVE-2023-28807/"}
