When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.","state":0,"publishedAt":"2021-03-01T12:00:20+00:00","modifiedAt":"2026-10-08T21:03:14.632+00:00","affected":[{"ecosystem":"Vendor product","name":"Apache Tomcat","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Apache Tomcat\",\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"10.0.0\",\n                            \"status\": \"affected\",\n                            \"version\": \"Apache Tomcat 10\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"9.0.41\",\n                            \"status\": \"affected\",\n                            \"version\": \"Apache Tomcat 9\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"8.5.61\",\n                            \"status\": \"affected\",\n                            \"version\": \"Apache Tomcat 8.5\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"7.0.107\",\n                            \"status\": \"affected\",\n                            \"version\": \"Apache Tomcat 7\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://lists.apache.org/thread.html/rfe62fbf9d4c314f166fe8c668e50e5d9dd882a99447f26f0367474bf%40%3Cannounce.tomcat.apache.org%3E","https://lists.apache.org/thread.html/rfe62fbf9d4c314f166fe8c668e50e5d9dd882a99447f26f0367474bf%40%3Cdev.tomcat.apache.org%3E","https://lists.apache.org/thread.html/rfe62fbf9d4c314f166fe8c668e50e5d9dd882a99447f26f0367474bf%40%3Cannounce.apache.org%3E","https://lists.apache.org/thread.html/rfe62fbf9d4c314f166fe8c668e50e5d9dd882a99447f26f0367474bf%40%3Cusers.tomcat.apache.org%3E","https://lists.apache.org/thread.html/rf6d5d57b114678d8898005faef31e9fd6d7c981fcc4ccfc3bc272fc9%40%3Cdev.tomcat.apache.org%3E","http://www.openwall.com/lists/oss-security/2021/03/01/2","https://lists.debian.org/debian-lts-announce/2021/03/msg00018.html","https://www.debian.org/security/2021/dsa-4891","https://lists.apache.org/thread.html/r8a2ac0e476dbfc1e6440b09dcc782d444ad635d6da26f0284725a5dc%40%3Cusers.tomcat.apache.org%3E","https://lists.apache.org/thread.html/rb51ccd58b2152fc75125b2406fc93e04ca9d34e737263faa6ff0f41f%40%3Cusers.tomcat.apache.org%3E","https://lists.apache.org/thread.html/r732b2ca289dc02df2de820e8775559abd6c207f159e39f559547a085%40%3Cusers.tomcat.apache.org%3E","https://lists.apache.org/thread.html/r11ce01e8a4c7269b88f88212f21830edf73558997ac7744f37769b77%40%3Cusers.tomcat.apache.org%3E","https://www.oracle.com//security-alerts/cpujul2021.html","https://security.netapp.com/advisory/ntap-20210409-0002/","https://www.oracle.com/security-alerts/cpuoct2021.html","https://www.oracle.com/security-alerts/cpujan2022.html","https://security.gentoo.org/glsa/202208-34"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2021-25329","license":"CVE Program Terms of Use","key":"cve-program:CVE-2021-25329","identifiers":["CVE-2021-25329"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
