Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-27317 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 2.11.0; fixed in 2.11.4\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 2.11.0; fixed in 2.11.4\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 2.4.0; fixed in 2.10.6\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 2.4.0; fixed in 2.10.6\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 3.0.0; fixed in 3.0.3\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 3.0.0; fixed in 3.0.3\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 3.1.0; fixed in 3.1.3\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 3.1.0; fixed in 3.1.3\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 3.2.0; fixed in 3.2.1\n- org.apache.pulsar:pulsar-functions-worker (Maven): affected from 3.2.0; fixed in 3.2.1\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-2024-27317/ (Markdown: https://insights.sbomify.com/CVE-2024-27317/index.md)","id":"CVE-2024-27317","markdown":"https://insights.sbomify.com/CVE-2024-27317/index.md","name":"CVE-2024-27317","record":{"aliases":["GHSA-jg2g-4rjg-cmqh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Pulsar","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit directory traversal in Pulsar Functions Worker to create or modify files outside the intended extraction directory.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"pulsar","vendor":"apache"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"In Pulsar Functions Worker, authenticated users can upload functions in jar or nar files. These files, essentially zip files, are extracted by the Functions Worker. However, if a malicious file is uploaded, it could exploit a directory traversal vulnerability. This occurs when the filenames in the zip files, which aren't properly validated, contain special elements like \"..\", altering the directory path. This could allow an attacker to create or modify files outside of the designated extraction directory, potentially influencing system behavior. This vulnerability also applies to the Pulsar Broker when it is configured with \"functionsWorkerEnabled=true\".\n\nThis issue affects Apache Pulsar versions from 2.4.0 to 2.10.5, from 2.11.0 to
