Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20378 in the wild and no public exploit code.\n\nAffected product: IBM Guardium Data Encryption. 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-2021-20378/ (Markdown: https://insights.sbomify.com/CVE-2021-20378/index.md)","id":"CVE-2021-20378","markdown":"https://insights.sbomify.com/CVE-2021-20378/index.md","name":"CVE-2021-20378","record":{"aliases":["GHSA-7mrw-f6g3-g543"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Guardium Data Encryption","requires_auth":"low_privilege","summary":"Authenticated users can impersonate others due to sessions not being invalidated after logout in IBM Guardium Data Encryption.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"guardium_data_encryption","vendor":"ibm"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/I:L/UI:N/C:L/AC:L/S:U/AV:N/PR:L/A:L/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"IBM Guardium Data Encryption (GDE) 3.0.0.2 and 4.0.0.4 does not invalidate session after logout which could allow an authenticated user to impersonate another user on the system.
