An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-28169 exists.\n\nAffected packages and fixed versions:\n- org.eclipse.jetty:jetty-servlets (Maven): affected all versions; fixed in 9.4.41\n- org.eclipse.jetty:jetty-servlets (Maven): affected all versions; fixed in 9.4.41\n- org.eclipse.jetty:jetty-servlets (Maven): affected from 10.0.0; fixed in 10.0.3\n- org.eclipse.jetty:jetty-servlets (Maven): affected from 10.0.0; fixed in 10.0.3\n- org.eclipse.jetty:jetty-servlets (Maven): affected from 11.0.0; fixed in 11.0.3\n- org.eclipse.jetty:jetty-servlets (Maven): affected from 11.0.0; fixed in 11.0.3\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-2021-28169/ (Markdown: https://insights.sbomify.com/CVE-2021-28169/index.md)","id":"CVE-2021-28169","markdown":"https://insights.sbomify.com/CVE-2021-28169/index.md","name":"CVE-2021-28169","record":{"aliases":["DEBIAN-CVE-2021-28169","DLA-2688-1","GHSA-gwcr-j4wh-j3cq","OESA-2021-1249","UBUNTU-CVE-2021-28169"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web server","requires_auth":"none","summary":"Attackers can access protected WEB-INF resources like web.xml via doubly encoded paths in ConcatServlet, revealing sensitive application implementation details.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"jetty","vendor":"eclipse"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"hci","vendor":"netapp"},{"product":"management_services_for_element_software","vendor":"netapp"},{"product":"snap_creator_framework","vendor":"netapp"},{"product":"communications_cloud_native_core_policy","vendor":"oracle"},{"product":"rest_data_services","vendor":"oracle"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"For Eclipse Jetty versions \u003c= 9.4.40, \u003c= 10.0.2, \u003c= 11.0.2, it is possible for requests to the ConcatServlet with a doubly encoded path to access protected resources within the WEB-INF directory.
