How to fix?
org.apache.tomcat:catalina to version 6.0.20 or higher.
org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.
Affected versions of this package are vulnerable to Information Exposure. Due to insufficient error checking in some authentication classes, Tomcat allows for the enumeration (brute force testing) of user names by supplying illegally URL encoded passwords. The attack is possible if FORM based authentication (j_security_check) is used with the
MemoryRealm.Note that in early versions, the
JDBCRealm were alsoaffected.This was fixed in revision 781382.
