Environment:

  • Version: v5.6.7
  • Installation/Running method:
    • Visual Studio Extension
    • NuGet package
    • Standalone tool
      • DotNet Core Tool from NuGet
      • security-scan4x.zip from GitHub Release section
  • Operating System:
    • Windows
    • Linux
    • Mac

Describe the bug
Scanning an intentionally vulnerable .NET 6 project with the stand-alone runner does not yield any detection results.

Repro
Create a .NET 6 Console project, and use the following code in the Program.cs file.

using System.Diagnostics;
using System.Xml;

var rnd = new Random();
byte[] buffer = new byte[16];
rnd.NextBytes(buffer);
var byteString = BitConverter.ToString(buffer);

var doc = new XmlDocument { XmlResolver = null };
doc.Load("/config.xml");
var results = doc.SelectNodes("/Config/Devices/Device[id='" + args[0] + "']");

var p = new Process();
p.StartInfo.FileName = "exportLegacy.exe";
p.StartInfo.Arguments = " -user " + args[0] + " -role user";
p.Start();

I would expect some detection results when scanning this project, considering those vulnerabilities are copied directly from the https://security-code-scan.github.io/ page, but instead I get the following output:

C:\Repos\security-spike>security-scan TestLib.sln -f -v
