It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-9484 exists.\n\nAffected packages and fixed versions:\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.0.0-M1; fixed in 10.0.0-M5\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.0.0-M1; fixed in 10.0.0-M5\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 7.0.104\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 7.0.104\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.0.0; fixed in 8.5.55\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.0.0; fixed in 8.5.55\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0; fixed in 9.0.35\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0; fixed in 9.0.35\n- tomcat (Bitnami): affected from 7.0.0; fixed in 7.0.108, 8.5.63, 9.0.43\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 10.0.0-M1; fixed in 10.0.0-M5\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 10.0.0-M1; fixed in 10.0.0-M5\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 7.0.0; fixed in 7.0.104\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-2020-9484/ (Markdown: https://insights.sbomify.com/CVE-2020-9484/index.md)","id":"CVE-2020-9484","markdown":"https://insights.sbomify.com/CVE-2020-9484/index.md","name":"CVE-2020-9484","record":{"aliases":["BIT-tomcat-2020-9484","DEBIAN-CVE-2020-9484","DLA-2217-1","GHSA-344f-f5vg-2jfj","MGASA-2020-0277","RHSA-2020:2483","RHSA-2020:2506","RHSA-2020:2529","RHSA-2020:2530","SUSE-SU-2020:1363-1","SUSE-SU-2020:1364-1","SUSE-SU-2020:1365-1","UBUNTU-CVE-2020-9484","openSUSE-SU-2020:0711-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution in Apache Tomcat by exploiting unsafe deserialization in the PersistenceManager when specific file control and configuration conditions are met.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"epolicy_orchestrator","vendor":"mcafee"},{"product":"leap","vendor":"opensuse"},{"product":"agile_engineering_data_management","vendor":"oracle"},{"product":"agile_product_lifecycle_management","vendor":"oracle"},{"product":"communications_cloud_native_core_binding_support_function","vendor":"oracle"},{"product":"communications_cloud_native_core_policy","vendor":"oracle"},{"product":"communications_diameter_signaling_router","vendor":"oracle"},{"product":"communications_element_manager","vendor":"oracle"},{"product":"communications_instant_messaging_server","vendor":"oracle"},{"product":"communications_session_report_manager","vendor":"oracle"},{"product":"communications_session_route_manager","vendor":"oracle"},{"product":"database","vendor":"oracle"},{"product":"fmw_platform","vendor":"oracle"},{"product":"hospitality_guest_access","vendor":"oracle"},{"product":"instantis_enterprisetrack","vendor":"oracle"},{"product":"managed_file_transfer","vendor":"oracle"},{"product":"mysql_enterprise_monitor","vendor":"oracle"},{"product":"retail_order_broker","vendor":"oracle"},{"product":"siebel_apps_-_marketing","vendor":"oracle"},{"product":"siebel_ui_framework","vendor":"oracle"},{"product":"transportation_management","vendor":"oracle"},{"product":"workload_manager","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":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter=\"null\" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control.
