CVE-2019-0604 SharePoint Remote code execution (RCE) vulnerability

A security expert found a flaw in SharePoint that could be exploited to remotely execute arbitrary code by sending a specially crafted SharePoint application package.

Summary:
A few days ago I saw a post from Alienvault which says attackers are still exploiting SharePoint vulnerability to attack Middle East government organization. Having said that I found Income Tax Department India and MIT Sloan was also vulnerable to CVE-2019-0604 a remote code execution vulnerability which exists in Microsoft SharePoint. A malicious actor could exploit this vulnerability by simply sending a specially crafted SharePoint application package.

Technical analysis:
I found this vulnerability during my free time while I was browsing to ZoomEye to find such component. The application (incometaxindia.gov.in) was found to be vulnerable as it was using SharePoint as a technology to host its service. To verify this I’ve sent a crafted payload which enable the remote server (incometaxindia.gov.in) to perform a DNS lookup on my burp collaborator. You can do this manual by sending the crafted XML payload or via desharialize.

Aside, MIT Sloan School of Management was also found to be vulnerable with CVE-2019-0604.

UN hacked: Attackers got in via SharePoint vulnerability

In summer 2019, hackers broke into over 40 (and possibly more) UN servers in offices in Geneva and Vienna and downloaded “sensitive data that could have far-reaching repercussions for staff, individuals, and organizations communicating with and doing business with the UN,” The New Humanitarian reported on Wednesday. The UN, unfortunately, did not share that discovery with the authorities, the public, or even the potentially affected staff, and we now know about it only because TNH … More
