An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-4400 in the wild and no public exploit code.\n\nAffected product: IBM Verify Gateway (IVG). 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-2020-4400/ (Markdown: https://insights.sbomify.com/CVE-2020-4400/index.md)","id":"CVE-2020-4400","markdown":"https://insights.sbomify.com/CVE-2020-4400/index.md","name":"CVE-2020-4400","record":{"aliases":["GHSA-9v3j-42rv-3cwm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Verify Gateway","requires_auth":"none","summary":"Inadequate account lockout settings in IBM Verify Gateway allow remote attackers to brute force credentials and take over accounts.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"verify_gateway","vendor":"ibm"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AC:L/UI:N/I:N/S:U/C:H/PR:N/AV:N/A:N/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"IBM Verify Gateway (IVG) 1.0.0 and 1.0.1 uses an inadequate account lockout setting that could allow a remote attacker to brute force account credentials.
