The Microsoft .NET Framework installation on the remote host is missing a security update. It is, therefore, affected by multiple vulnerabilities, as follows:
Security feature bypass in ASP.NET. An attacker can bypass the security checks that prevents an attacker from accessing internal applications in a website. (CVE-2023-36560)
Privilege escalation vulnerability in FTP component of .NET Framework. An attacker can inject arbitrary commands to the FTP server. (CVE-2023-36049)
Information disclosure vulnerability in .NET Framework. An attacker can obtain the ObjRef URI which could lead to remote code execution. (CVE-2024-29059
