Apache Software Foundation Apache Tomcat
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache Tomcat 的 DIGEST 身份验证器中存在通过重放捕获绕过身份认证的漏洞。如果在发出 windowSize 个请求之前，客户端发送了一个带有位于重放窗口上边界的 nonceCount 的 DIGEST 认证请求，那么该请求可以在关联的 nonceCount 仍然处于重放窗口期间被重放一次。 此问题影响 Apache Tomcat 以下版本：11.0.0-M1 到 11.0.24，10.1.0-M1 到 10.1.57，以及 9.0.0.M1 到 9.0.120。 在创建 CVE 时，以下版本已经

Vulnerability Title
Apache Tomcat: Limited replay attack possible with DIGEST authentication
Source: CVE Program / CVE List V5
Vulnerability Description
Authentication Bypass by Capture-replay vulnerability in Apache Tomcat's DIGEST authenticator. If, before windowSize requests have been made, a client makes a DIGEST
authenticated request with a nonceCount on the upper boundary of the
replay window then that request is replayable once only while the
associated nonceCount remains within the replay window.
This 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.
The following versions were EOL at the time the CVE was created but are
known 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.
Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.
