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-2021-33600 in the wild and no public exploit code.\n\nAffected product: F-Secure Internet Gatekeeper. 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-2021-33600/ (Markdown: https://insights.sbomify.com/CVE-2021-33600/index.md)","id":"CVE-2021-33600","markdown":"https://insights.sbomify.com/CVE-2021-33600/index.md","name":"CVE-2021-33600","record":{"aliases":["GHSA-453r-cx7v-94wr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"F-Secure Internet Gatekeeper","requires_auth":"low_privilege","summary":"An unauthenticated attacker can cause a denial of service in F-Secure Internet Gatekeeper by sending a large username parameter to the web interface.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"F-SecureUS","cpe":[{"product":"internet_gatekeeper","vendor":"f-secure"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"A denial-of-service (DoS) vulnerability was discovered in the web user interface of F-Secure Internet Gatekeeper.
