var xDoc = XDocument.Load(fileName);I am using above code in a function to load an XML file. Functionality wise its working fine but it is showing following Veracode Flaw after Veracode check.
Description
The product processes an XML document that can contain XML entities with URLs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. By default, the XML entity resolver will attempt to resolve and retrieve external references. If attacker-controlled XML can be submitted to one of these functions, then the attacker could gain access to information about an internal network, local filesystem, or other sensitive data. This is known as an XML eXternal Entity (XXE) attack.
Recommendations
Configure the XML parser to disable external entity resolution.
What I need to do to resolve it.

public void updateConfigFile(string con)
{
//updating config file
XmlDocument XmlDoc = new XmlDocument();
//Loading the Config file
XmlDoc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
foreach (XmlElement xElement in XmlDoc.DocumentElement)
{
if (xElement.Name == "connectionStrings")
{
//setting the coonection string
xElement.FirstChild.Attributes[2].Value = con;
}
}
//writing the connection string in config file
XmlDoc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
}
if helped kindly accept the answer.
