Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-4319 in the wild and no public exploit code.\n\nAffected product: IBM MQ Appliance. 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-2020-4319/ (Markdown: https://insights.sbomify.com/CVE-2020-4319/index.md)","id":"CVE-2020-4319","markdown":"https://insights.sbomify.com/CVE-2020-4319/index.md","name":"CVE-2020-4319","record":{"aliases":["GHSA-r542-g4pm-8f6m"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM MQ","requires_auth":"low_privilege","summary":"An authenticated user can obtain sensitive information via data leaks in error messages within the pre-v7 pubsub logic of IBM MQ.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"mq_appliance","vendor":"ibm"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.0/UI:N/I:N/PR:L/S:U/C:L/AC:H/A:N/AV:N/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"IBM MQ, IBM MQ Appliance, and IBM MQ for HPE NonStop 8.0, 9.1 LTS, and 9.1 CD could allow under special circumstances, an authenticated user to obtain sensitive information due to a data leak from an error message within the pre-v7 pubsub logic.
