Zimbra Collaboration (ZCS) 10.0 and 10.1 contains an LDAP injection vulnerability in the Mailbox SOAP service within a FolderAction operation. The application fails to properly sanitize user-supplied input before incorporating it into an LDAP search filter. An authenticated attacker can exploit this issue by sending a crafted SOAP request that manipulates the LDAP query, allowing retrieval of sensitive directory attributes.
