Executive Summary

This vulnerability is an LDAP injection issue found in Zimbra Collaboration (ZCS) versions 10.0 and 10.1. It occurs in the Mailbox SOAP service within a FolderAction operation. The application does not properly sanitize user input before using it in an LDAP search filter. As a result, an authenticated attacker can send a specially crafted SOAP request that manipulates the LDAP query.

This manipulation allows the attacker to retrieve sensitive directory attributes that they should not normally have access to.

Impact Analysis

Exploiting this vulnerability can allow an authenticated attacker to access sensitive directory information by manipulating LDAP queries. This could lead to unauthorized disclosure of sensitive data stored in the directory, potentially compromising user information and internal system details.
