A bug in Windows Remote Desktop protocol allows unauthenticated users to run arbitrary code via a specially crafted request to the service. This affects Windows 7/Windows Server 2008 and earlier releases. Given the ubiquity of RDP in corporate environments and the trusted nature of RDP, this could pose serious concerns for ransomware attacks much like WannaCry.
Patches are released for Windows 7/2008 Operating systems as well as Windows XP.

The SolarWinds Orion API is vulnerable to authentication bypass that could allow a remote attacker to execute API commands.
This API is a central part of the Orion platform with highly privileged access to all Orion platform components. API authentication can be bypassed by including specific parameters in the `Request.PathInfo` portion of a URI request, which could allow an attacker to execute unauthenticated API commands. In particular, if an attacker appends a `PathInfo` parameter of WebResource.adx, ScriptResource.adx, i18n.ashx, or Skipi18n to a request to a SolarWinds Orion server, SolarWinds may set the `SkipAuthorization` flag, which may allow the API request to be processed without requiring authentication.
Patches are available and as of 2020-12-24 organizations should be on one of the following versions to mitigate this weakness:
- 2019.4 HF 6 (released December 14, 2020)
- 2020.2.1 HF 2 (released December 15, 2020)
- 2019.2 SUPERNOVA Patch (released December 23,…

A remote code execution vulnerability codenamed "SigRed" exists in Windows Domain Name System servers when they fail to properly handle requests. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the Local System Account. Windows servers that are configured as DNS servers are at risk from this vulnerability.
To exploit the vulnerability, an unauthenticated attacker could send malicious requests to a Windows DNS server.
The update addresses the vulnerability by modifying how Windows DNS servers handle requests.

CVE-2020-17087 is a pool-based buffer overflow vulnerability in the Windows Kernel Cryptography Driver (cng.sys). The vulnerability arises from input/output controller (IOCTL) 0x390400 processing and could allow a local attacker to escalate privileges, including for sandbox escape. The vulnerability was initially released as a zero-day by Google's Project Zero team; it was patched on November 10, 2020, as part of Microsoft's November 2020 Patch Tuesday release.
