An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2016-8735 in the wild since at least 12 May 2023.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat-catalina (Maven): affected all versions; fixed in 6.0.48\n- org.apache.tomcat:tomcat-catalina (Maven): affected all versions; fixed in 6.0.48\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 7.0.0; fixed in 7.0.73\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 7.0.0; fixed in 7.0.73\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 8.0.0; fixed in 8.0.39\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 8.0.0; fixed in 8.0.39\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 8.5.0; fixed in 8.5.7\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 8.5.0; fixed in 8.5.7\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 9.0.0.M1; fixed in 9.0.0.M12\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 9.0.0.M1; fixed in 9.0.0.M12\n- org.apache.tomcat:tomcat-catalina-jmx-remote (Maven): affected all versions; fixed in 6.0.48\n- org.apache.tomcat:tomcat-catalina-jmx-remote (Maven): affected all versions; fixed in 6.0.48\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-2016-8735/ (Markdown: https://insights.sbomify.com/CVE-2016-8735/index.md)","id":"CVE-2016-8735","markdown":"https://insights.sbomify.com/CVE-2016-8735/index.md","name":"CVE-2016-8735","record":{"aliases":["GHSA-cw54-59pw-4g8c","UBUNTU-CVE-2016-8735","USN-7242-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Apache Tomcat servers if the JmxRemoteLifecycleListener is enabled and JMX ports are accessible.","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":"7-mode_transition_tool","vendor":"netapp"},{"product":"oncommand_insight","vendor":"netapp"},{"product":"oncommand_shift","vendor":"netapp"},{"product":"snap_creator_framework","vendor":"netapp"},{"product":"agile_engineering_data_management","vendor":"oracle"},{"product":"agile_product_lifecycle_management","vendor":"oracle"},{"product":"communications_application_session_controller","vendor":"oracle"},{"product":"communications_instant_messaging_server","vendor":"oracle"},{"product":"communications_interactive_session_recorder","vendor":"oracle"},{"product":"hospitality_guest_access","vendor":"oracle"},{"product":"micros_relate_crm_software","vendor":"oracle"},{"product":"micros_retail_xbri_loss_prevention","vendor":"oracle"},{"product":"mysql_enterprise_monitor","vendor":"oracle"},{"product":"retail_convenience_and_fuel_pos_software","vendor":"oracle"},{"product":"transportation_management","vendor":"oracle"},{"product":"jboss_enterprise_web_server","vendor":"redhat"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports.
