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-2016-8741 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.qpid:qpid-broker (Maven): affected from 6.0.0; fixed in 6.0.6\n- org.apache.qpid:qpid-broker (Maven): affected from 6.0.0; fixed in 6.0.6\n- org.apache.qpid:qpid-broker (Maven): affected from 6.1.0; fixed in 6.1.1\n- org.apache.qpid:qpid-broker (Maven): affected from 6.1.0; fixed in 6.1.1\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-2016-8741/ (Markdown: https://insights.sbomify.com/CVE-2016-8741/index.md)","id":"CVE-2016-8741","markdown":"https://insights.sbomify.com/CVE-2016-8741/index.md","name":"CVE-2016-8741","record":{"aliases":["GHSA-8vvh-crqv-jm64"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Java message broker","requires_auth":"none","summary":"Remote attackers can enumerate valid user accounts in Apache Qpid Broker-J when SCRAM authentication is enabled due to premature SASL negotiation termination.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"qpid_broker-j","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Apache Qpid Broker for Java can be configured to use different so called AuthenticationProviders to handle user authentication.

It was discovered that these AuthenticationProviders in Apache Qpid Broker for Java 6.0.x before 6.0.6 and 6.1.x before 6.1.1 prematurely terminate the SCRAM SASL negotiation if the provided user name does not exist thus allowing remote attacker to determine the existence of user accounts.
