Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-1993 in the wild and no public exploit code.\n\nAffected product: Paloaltonetworks Pan-Os. 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-2020-1993/ (Markdown: https://insights.sbomify.com/CVE-2020-1993/index.md)","id":"CVE-2020-1993","markdown":"https://insights.sbomify.com/CVE-2020-1993/index.md","name":"CVE-2020-1993","record":{"aliases":["GHSA-w8pj-jc9c-cq4v"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PAN-OS GlobalProtect Portal","requires_auth":"low_privilege","summary":"Attackers can hijack user sessions in PAN-OS GlobalProtect Portal by fixing session IDs, leading to account takeover.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"The GlobalProtect Portal feature in PAN-OS does not set a new session identifier after a successful user login, which allows session fixation attacks, if an attacker is able to control a user's session ID.
