Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-29843 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-2021-29843/ (Markdown: https://insights.sbomify.com/CVE-2021-29843/index.md)","id":"CVE-2021-29843","markdown":"https://insights.sbomify.com/CVE-2021-29843/index.md","name":"CVE-2021-29843","record":{"aliases":["GHSA-w36r-438f-hgrv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM MQ","requires_auth":"low_privilege","summary":"Attackers can cause a denial of service in IBM MQ by exploiting an issue in message property processing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"mq_appliance","vendor":"ibm"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/I:N/C:N/AC:H/S:U/A:H/UI:N/PR:L/AV:N/RC:C/RL:O/E:U","version":"3.0"},"cwes":[],"description":"IBM MQ 9.1 LTS, 9.1 CD, 9.2 LTS, and 9.2CD is vulnerable to a denial of service attack caused by an issue processing message properties.
