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-2022-33682 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.pulsar:pulsar-broker (Maven): affected all versions; fixed in 2.7.5\n- org.apache.pulsar:pulsar-broker (Maven): affected all versions; fixed in 2.7.5\n- org.apache.pulsar:pulsar-broker (Maven): affected from 2.10.0; fixed in 2.10.1\n- org.apache.pulsar:pulsar-broker (Maven): affected from 2.10.0; fixed in 2.10.1\n- org.apache.pulsar:pulsar-broker (Maven): affected from 2.8.0; fixed in 2.8.4\n- org.apache.pulsar:pulsar-broker (Maven): affected from 2.8.0; fixed in 2.8.4\n- org.apache.pulsar:pulsar-broker (Maven): affected from 2.9.0; fixed in 2.9.3\n- org.apache.pulsar:pulsar-broker (Maven): affected from 2.9.0; fixed in 2.9.3\n- org.apache.pulsar:pulsar-proxy (Maven): affected all versions; fixed in 2.7.5\n- org.apache.pulsar:pulsar-proxy (Maven): affected all versions; fixed in 2.7.5\n- org.apache.pulsar:pulsar-proxy (Maven): affected from 2.10.0; fixed in 2.10.1\n- org.apache.pulsar:pulsar-proxy (Maven): affected from 2.10.0; fixed in 2.10.1\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-2022-33682/ (Markdown: https://insights.sbomify.com/CVE-2022-33682/index.md)","id":"CVE-2022-33682","markdown":"https://insights.sbomify.com/CVE-2022-33682/index.md","name":"CVE-2022-33682","record":{"aliases":["GHSA-jvf3-mfxv-jcqr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Pulsar","requires_auth":"none","summary":"Disabled TLS hostname verification in Apache Pulsar clients allows man-in-the-middle attacks to intercept sensitive data and credentials.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"pulsar","vendor":"apache"}],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"TLS hostname verification cannot be enabled in the Pulsar Broker's Java Client, the Pulsar Broker's Java Admin Client, the Pulsar WebSocket Proxy's Java Client, and the Pulsar Proxy's Admin Client leaving intra-cluster connections and geo-replication connections vulnerable to man in the middle attacks, which could leak credentials, configuration data, message data, and any other data sent by these clients. The vulnerability is for both the pulsar+ssl protocol and HTTPS. An attacker can only take advantage of this vulnerability by taking control of a machine 'between' the client and the server. The attacker must then actively manipulate traffic to perform the attack by providing the client with a cryptographically valid certificate for an unrelated host.
