CVE-2018-8034

CVSS v2.0

7.8

High

VectorAV:N/AC:L/Au:N/C:C/I:N/A:N
Name of the Vulnerable Software and Affected Versions Apache Tomcat versions 7.0.35 through 7.0.88 Apache Tomcat versions 8.0.0.RC1 through 8.0.52 Apache Tomcat versions 8.5.0 through 8.5.31 Apache Tomcat versions 9.0.0.M1 through 9.0.9
Description The issue is related to the host name verification when using TLS with the WebSocket client, which was missing and is now enabled by default. This allows a remote attacker to bypass existing security restrictions by exploiting errors in host name checking during Transport Layer Security (TLS) protocol use.
Recommendations For Apache Tomcat versions 7.0.35 through 7.0.88, enable host name verification for the WebSocket client. For Apache Tomcat versions 8.0.0.RC1 through 8.0.52, enable host name verification for the WebSocket client. For Apache Tomcat versions 8.5.0 through 8.5.31, enable host name verification for the WebSocket client. For Apache Tomcat versions 9.0.0.M1 through 9.0.9, enable host name verification for the WebSocket client.
