The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.\n\nIf all of the following were true, a malicious user was able to view security sensitive files and/or inject content into those files:\n- writes enabled for the default servlet (disabled by default)\n- support for partial PUT (enabled by default)\n- a target URL for security sensitive uploads that was a sub-directory of a target URL for public uploads\n- attacker knowledge of the names of security sensitive files being uploaded\n- the security sensitive files also being uploaded via partial PUT\n\nIf all of the following were true, a malicious user was able to perform remote code execution:\n- writes enabled for the default servlet (disabled by default)\n- support for partial PUT (enabled by default)\n- application was using Tomcat's file based session persistence with the default storage location\n- application included a library that may be leveraged in a deserialization attack\n\nUsers are recommended to upgrade to version 11.0.3, 10.1.35 or 9.0.99, which fixes the issue.","affected":[{"package":{"name":"org.apache.tomcat:tomcat-catalina","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat-catalina"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"11.0.0-M1"},{"fixed":"11.0.3"}]}],"versions":["11.0.0","11.0.0-M1","11.0.0-M10","11.0.0-M11","11.0.0-M12","11.0.0-M13","11.0.0-M14","11.0.0-M15","11.0.0-M16","11.0.0-M17","11.0.0-M18","11.0.0-M19","11.0.0-M20","11.0.0-M21","11.0.0-M22","11.0.0-M24","11.0.0-M25","11.0.0-M26","11.0.0-M3","11.0.0-M4","11.0.0-M5","11.0.0-M6","11.0.0-M7","11.0.0-M9","11.0.1","11.0.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-83qj-6fr2-vhqg/GHSA-83qj-6fr2-vhqg.json"}},{"package":{"name":"org.apache.tomcat:tomcat-catalina","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat-catalina"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.1.0-M1"},{"fixed":"10.1.35"}]}],"versions":["10.1.0","10.1.0-M1","10.1.0-M10","10.1.0-M11","10.1.0-M12","10.1.0-M14","10.1.0-M15","10.1.0-M16","10.1.0-M17","10.1.0-M2","10.1.0-M4","10.1.0-M5","10.1.0-M6","10.1.0-M7","10.1.0-M8","10.1.1","10.1.10","10.1.11","10.1.12","10.1.13","10.1.14","10.1.15","10.1.16","10.1.17","10.1.18","10.1.19","10.1.2","10.1.20","10.1.23","10.1.24","10.1.25","10.1.26","10.1.28","10.1.29","10.1.30","10.1.31","10.1.33","10.1.34","10.1.4","10.1.5","10.1.6","10.1.7","10.1.8","10.1.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-83qj-6fr2-vhqg/GHSA-83qj-6fr2-vhqg.json"}},{"package":{"name":"org.apache.tomcat:tomcat-catalina","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat-catalina"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.0.M1"},{"fixed":"9.0.99"}]}],"versions":["9.0.0.M1","9.0.0.M10","9.0.0.M11","9.0.0.M13","9.0.0.M15","9.0.0.M17","9.0.0.M18","9.0.0.M19","9.0.0.M20","9.0.0.M21","9.0.0.M22","9.0.0.M25","9.0.0.M26","9.0.0.M27","9.0.0.M3","9.0.0.M4","9.0.0.M6","9.0.0.M8","9.0.0.M9","9.0.1","9.0.10","9.0.11","9.0.12","9.0.13","9.0.14","9.0.16","9.0.17","9.0.19","9.0.2","9.0.20","9.0.21","9.0.22","9.0.24","9.0.26","9.0.27","9.0.29","9.0.30","9.0.31","9.0.33","9.0.34","9.0.35","9.0.36","9.0.37","9.0.38","9.0.39","9.0.4","9.0.40","9.0.41","9.0.43","9.0.44","9.0.45","9.0.46","9.0.48","9.0.5","9.0.50","9.0.52","9.0.53","9.0.54","9.0.55","9.0.56","9.0.58","9.0.59","9.0.6","9.0.60","9.0.62","9.0.63","9.0.64","9.0.65","9.0.67","9.0.68","9.0.69","9.0.7","9.0.70","9.0.71","9.0.72","9.0.73","9.0.74","9.0.75","9.0.76","9.0.78","9.0.79","9.0.8","9.0.80","9.0.81","9.0.82","9.0.83","9.0.84","9.0.85","9.0.86","9.0.87","9.0.88","9.0.89","9.0.90","9.0.91","9.0.93","9.0.94","9.0.95","9.0.96","9.0.97","9.0.98"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-83qj-6fr2-vhqg/GHSA-83qj-6fr2-vhqg.json"}},{"package":{"name":"org.apache.tomcat.embed:tomcat-embed-core","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"11.0.0-M1"},{"fixed":"11.0.3"}]}],"versions":["11.0.0","11.0.0-M1","11.0.0-M10","11.0.0-M11","11.0.0-M12","11.0.0-M13","11.0.0-M14","11.0.0-M15","11.0.0-M16","11.0.0-M17","11.0.0-M18","11.0.0-M19","11.0.0-M20","11.0.0-M21","11.0.0-M22","11.0.0-M24","11.0.0-M25","11.0.0-M26","11.0.0-M3","11.0.0-M4","11.0.0-M5","11.0.0-M6","11.0.0-M7","11.0.0-M9","11.0.1","11.0.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-83qj-6fr2-vhqg/GHSA-83qj-6fr2-vhqg.json"}},{"package":{"name":"org.apache.tomcat.embed:tomcat-embed-core","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.1.0-M1"},{"fixed":"10.1.35"}]}],"versions":["10.1.0","10.1.0-M1","10.1.0-M10","10.1.0-M11","10.1.0-M12","10.1.0-M14","10.1.0-M15","10.1.0-M16","10.1.0-M17","10.1.0-M2","10.1.0-M4","10.1.0-M5","10.1.0-M6","10.1.0-M7","10.1.0-M8","10.1.1","10.1.10","10.1.11","10.1.12","10.1.13","10.1.14","10.1.15","10.1.16","10.1.17","10.1.18","10.1.19","10.1.2","10.1.20","10.1.23","10.1.24","10.1.25","10.1.26","10.1.28","10.1.29","10.1.30","10.1.31","10.1.33","10.1.34","10.1.4","10.1.5","10.1.6","10.1.7","10.1.8","10.1.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-83qj-6fr2-vhqg/GHSA-83qj-6fr2-vhqg.json"}},{"package":{"name":"org.apache.tomcat.embed:tomcat-embed-core","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.0.M1"},{"fixed":"9.0.99"}]}],"versions":["9.0.0.M1","9.0.0.M10","9.0.0.M11","9.0.0.M13","9.0.0.M15","9.0.0.M17","9.0.0.M18","9.0.0.M19","9.0.0.M20","9.0.0.M21","9.0.0.M22","9.0.0.M25","9.0.0.M26","9.0.0.M27","9.0.0.M3","9.0.0.M4","9.0
