It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-25329 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.0.0-M1; fixed in 10.0.2\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.0.0-M1; fixed in 10.0.2\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 7.0.108\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 7.0.108\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.0.0; fixed in 8.5.61\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.0.0; fixed in 8.5.61\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0; fixed in 9.0.41\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0; fixed in 9.0.41\n- tomcat (Bitnami): affected from 7.0.0; fixed in 7.0.108, 8.5.62, 9.0.42, 10.0.1\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-2021-25329/ (Markdown: https://insights.sbomify.com/CVE-2021-25329/index.md)","id":"CVE-2021-25329","markdown":"https://insights.sbomify.com/CVE-2021-25329/index.md","name":"CVE-2021-25329","record":{"aliases":["BIT-tomcat-2021-25329","CLSA-2024-1716916085","CLSA-2024-1723060627","DEBIAN-CVE-2021-25329","GHSA-jgwr-3qm3-26f3","SUSE-SU-2021:1431-1","UBUNTU-CVE-2021-25329"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"low_privilege","summary":"Incomplete fix for CVE-2020-9484 allows remote code execution via deserialization in Apache Tomcat under specific configuration edge cases.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"},{"product":"debian_linux","vendor":"debian"},{"product":"agile_product_lifecycle_management","vendor":"oracle"},{"product":"communications_cloud_native_core_policy","vendor":"oracle"},{"product":"communications_cloud_native_core_security_edge_protection_proxy","vendor":"oracle"},{"product":"communications_instant_messaging_server","vendor":"oracle"},{"product":"database","vendor":"oracle"},{"product":"graph_server_and_client","vendor":"oracle"},{"product":"instantis_enterprisetrack","vendor":"oracle"},{"product":"managed_file_transfer","vendor":"oracle"},{"product":"mysql_enterprise_monitor","vendor":"oracle"},{"product":"siebel_ui_framework","vendor":"oracle"}],"cvss":{"score":7,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The fix for CVE-2020-9484 was incomplete.
