Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20517 in the wild and no public exploit code.\n\nAffected product: IBM WebSphere Application Server ND. 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-2021-20517/ (Markdown: https://insights.sbomify.com/CVE-2021-20517/index.md)","id":"CVE-2021-20517","markdown":"https://insights.sbomify.com/CVE-2021-20517/index.md","name":"CVE-2021-20517","record":{"aliases":["GHSA-fppj-frvc-63q2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WebSphere Application Server","requires_auth":"low_privilege","summary":"Remote authenticated attackers can traverse directories to read and delete arbitrary files on IBM WebSphere Application Server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"websphere_application_server_nd","vendor":"ibm"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/UI:N/A:L/C:L/I:H/AV:N/AC:H/S:U/PR:L/RL:O/E:U/RC:C","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"IBM WebSphere Application Server Network Deployment 8.5 and 9.0 could allow a remote authenticated attacker to traverse directories.
