Descriptions
Microsoft SharePoint Server Information Disclosure Vulnerability
Vulnerabilidad de divulgación de información de Microsoft SharePoint Server
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Microsoft SharePoint. Authentication is required to exploit this vulnerability.
The specific flaw exists within the BaseXmlDataSource class. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the service account.
