| Detailed Description |
The version of Tomcat installed on the remote host is prior to 8.5.72. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_8.5.72_security-8 advisory.
- The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError. (CVE-2021-42340)
