It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-36994 exists.\n\nAffected product: QlikTech International AB QlikView. 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-2020-36994/ (Markdown: https://insights.sbomify.com/CVE-2020-36994/index.md)","id":"CVE-2020-36994","markdown":"https://insights.sbomify.com/CVE-2020-36994/index.md","name":"CVE-2020-36994","record":{"aliases":["GHSA-wjqm-4cvj-wx2q"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QlikView analytics software","requires_auth":"none","summary":"Local attackers can crash QlikView by pasting a long string into the FTP server address field, disrupting application availability.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"QlikView 12.50.20000.0 contains a denial of service vulnerability in the FTP server address input field that allows local attackers to crash the application.
