An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-45042 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- vault (Bitnami): affected from 1.4.0; fixed in 1.7.7, 1.8.6, 1.9.1\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-2021-45042/ (Markdown: https://insights.sbomify.com/CVE-2021-45042/index.md)","id":"CVE-2021-45042","markdown":"https://insights.sbomify.com/CVE-2021-45042/index.md","name":"CVE-2021-45042","record":{"aliases":["BIT-vault-2021-45042","GHSA-cr6r-4g38-f69g"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"HashiCorp Vault","requires_auth":"high_privilege","summary":"Authenticated users with write permissions can cause a panic and denial of service in HashiCorp Vault clusters using Integrated Storage.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vault","vendor":"hashicorp"}],"cvss":{"score":4.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In HashiCorp Vault and Vault Enterprise before 1.7.7, 1.8.x before 1.8.6, and 1.9.x before 1.9.1, clusters using the Integrated Storage backend allowed an authenticated user (with write permissions to a kv secrets engine) to cause a panic and denial of service of the storage backend.
