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-2020-2033 in the wild and no public exploit code.\n\nAffected product: Palo Alto Networks GlobalProtect App. 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-2020-2033/ (Markdown: https://insights.sbomify.com/CVE-2020-2033/index.md)","id":"CVE-2020-2033","markdown":"https://insights.sbomify.com/CVE-2020-2033/index.md","name":"CVE-2020-2033","record":{"aliases":["GHSA-8p7q-qxxf-h3cm"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"GlobalProtect VPN client","requires_auth":"none","summary":"A missing certificate validation in the GlobalProtect app allows attackers to steal pre-logon cookies via ARP spoofing, bypassing authentication controls.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"globalprotect","vendor":"paloaltonetworks"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"},{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"When the pre-logon feature is enabled, a missing certification validation in Palo Alto Networks GlobalProtect app can disclose the pre-logon authentication cookie to a man-in-the-middle attacker on the same local area network segment with the ability to manipulate ARP or to conduct ARP spoofing attacks.
