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-2019-11777 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.eclipse.paho:org.eclipse.paho.client.mqttv3 (Maven): affected all versions; fixed in 1.2.1\n- org.eclipse.paho:org.eclipse.paho.client.mqttv3 (Maven): affected all versions; fixed in 1.2.1\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-2019-11777/ (Markdown: https://insights.sbomify.com/CVE-2019-11777/index.md)","id":"CVE-2019-11777","markdown":"https://insights.sbomify.com/CVE-2019-11777/index.md","name":"CVE-2019-11777","record":{"aliases":["GHSA-63qc-p2x4-9fgf"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"MQTT client library","requires_auth":"none","summary":"Attackers can impersonate MQTT servers by bypassing TLS hostname verification, leading to data interception or injection.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"paho_java_client","vendor":"eclipse"}],"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-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-346","name":"Origin Validation Error"}],"description":"In the Eclipse Paho Java client library version 1.2.0, when connecting to an MQTT server using TLS and setting a host name verifier, the result of that verification is not checked.
