Severity: Medium

Vendor:
The Apache Software Foundation

Versions Affected:

connected LDAP server. 
With certain characters it is possible to modify the LDAP filter used to query the users on the connected LDAP server. 
By measuring the response time, arbitrary attribute data can be retrieved from LDAP user objects.

Mitigation:
