Apache Tomcat 9.0.71 < 9.0.74 DoS

high Nessus Plugin ID 176278

Language:

Synopsis

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

Description

The version of Tomcat installed on the remote host is prior to 9.0.74. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_9.0.74_security-9 advisory. The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7, 9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 9.0.74 or later.
