Vulnerability Details

CVEID: CVE-2016-0762

DESCRIPTION: Apache Tomcat could allow a remote attacker to obtain sensitive 
information, caused by the failure to process the user supplied password if 
the specified user name does not exist by the Realm implementation. An 
attacker could exploit this vulnerability to conduct a timing attack and 
determine valid usernames on the system.

CVSS Base Score: 5.3
