Allowing external control of system settings can disrupt service or cause an application to behave in unexpected ways.
Setting manipulation vulnerabilities occur when an attacker can control values that govern the behavior of the system, manage specific resources, or in some way affect the functionality of the application.
Because setting manipulation covers a diverse set of functions, any attempt at illustrating it will inevitably be incomplete. Rather than searching for a tight-knit relationship between the functions addressed in the setting manipulation category, take a step back and consider the sorts of system values that an attacker should not be allowed to control.
Example 1: The following VB code snippet reads a string from a Request
object and sets it as the active catalog for a database Connection
.
...
Dim conn As ADODB.Connection
Set conn = New ADODB.Connection
Dim rsTables As ADODB.Recordset
Dim Catalog As New ADOX.Catalog
Set Catalog.ActiveConnection = conn
Catalog.Create Request.Form("catalog")
