vulnerability in Apache Tomcat's DIGEST authenticator. If, before windowSize requests have been made, a client makes a DIGEST \nauthenticated request with a nonceCount on the upper boundary of the \nreplay window then that request is replayable once only while the \nassociated nonceCount remains within the replay window.\n\n\n\n \n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120.\n\n\n\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: from 8.5.0 through 8.5.100, from 7.0.30 through 7.0.109. Other unsupported versions may also be affected.\n\n\n\nUsers are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.", "title": "Vulnerability description" } ], "product_status": { "known_affected": [ "CloudLinux-7:tomcat-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-admin-webapps-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-admin-webapps-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-docs-webapp-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-docs-webapp-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-el-2.2-api-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-el-2.2-api-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-javadoc-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-javadoc-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-jsp-2.2-api-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-jsp-2.2-api-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-jsvc-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-jsvc-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-lib-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-lib-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-servlet-3.0-api-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-servlet-3.0-api-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-webapps-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-webapps-0:7.0.76-16.el7_9.tuxcare.els8.noarch" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2026-65905" }, { "category": "external", "summary": "https://lists.apache.org/thread/9v114xlpgbzrrbzz5vf9f6r2q4wnxwwj", "url": "https://lists.apache.org/thread/9v114xlpgbzrrbzz5vf9f6r2q4wnxwwj" }, { "category": "external", "summary": "http://www.openwall.com/lists/oss-security/2026/08/26/4", "url": "http://www.openwall.com/lists/oss-security/2026/08/26/4" } ], "release_date": "2026-08-25T22:17:00Z", "remediations": [ { "category": "no_fix_planned", "date": "2026-10-15T15:09:13.648808Z", "details": "- This issue is only relevant when Tomcat’s DIGEST authenticator is explicitly configured; installations that use other auth methods or handle authentication upstream are not affected. \n- A successful exploit requires an attacker to capture a valid DIGEST-authenticated request and for that request’s nonceCount to be exactly at the replay window’s upper boundary before the window fills—a narrow, timing‑dependent condition that at best allows a single replayed request with no persistent access or code execution. \n- When connections are protected by TLS, the required traffic capture is prevented, and the impact is limited to low‑level confidentiality/integrity effects with no availability impact, making this a low‑priority concern for centrally managed server/VM environments.", "product_ids": [ "CloudLinux-7:tomcat-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-admin-webapps-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-admin-webapps-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-docs-webapp-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-docs-webapp-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-el-2.2-api-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-el-2.2-api-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-javadoc-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-javadoc-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-jsp-2.2-api-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-jsp-2.2-api-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-jsvc-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-jsvc-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-lib-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-lib-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-servlet-3.0-api-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-servlet-3.0-api-0:7.0.76-16.el7_9.tuxcare.els8.noarch", "CloudLinux-7:tomcat-webapps-0:7.0.76-16.el7_9.noarch", "CloudLinux-7:tomcat-webapps-0:7.0.76-16.el7_9.tuxcare.els8.noarch" ] } ] } ] }
