Apache Tomcat: Limited replay attack possible with DIGEST authentication

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.
