Apache Tomcat 8.5.0 < 8.5.56 DoS

Medium Nessus Plugin ID 138097


The remote Apache Tomcat server is affected by a denial of service vulnerability.


The version of Tomcat installed on the remote host is prior to 8.5.56. It is, therefore, affected by a denial of service vulnerability as referenced in the fixed_in_apache_tomcat_8.5.56_security-8 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to Apache Tomcat version 8.5.56 or later.
