An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC), aka 'Netlogon Elevation of Privilege Vulnerability'.

A remote code execution vulnerability exists when the Windows TCP/IP stack improperly handles ICMPv6 Router Advertisement packets, aka 'Windows TCP/IP Remote Code Execution Vulnerability'.

In BIG-IP versions 15.0.0-15.1.0.3, 14.1.0-14.1.2.5, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1, the Traffic Management User Interface (TMUI), also referred to as the Configuration utility, has a Remote Code Execution (RCE) vulnerability in undisclosed pages.

In affected versions of Confluence Server and Data Center, an OGNL injection vulnerability exists that would allow an authenticated user, and in some instances an unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance. The vulnerable endpoints can be accessed by a non-administrator user or unauthenticated user if ‘Allow people to sign up to create their account’ is enabled. To check whether this is enabled go to COG > User Management > User Signup Options. The affected versions are before version 6.13.23, from version 6.14.0 before 7.4.11, from version 7.5.0 before 7.11.6, and from version 7.12.0 before 7.12.5.

A remote code execution vulnerability exists in Microsoft Exchange software when the software fails to properly handle objects in memory, aka 'Microsoft Exchange Memory Corruption Vulnerability'.

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.

Windows Installer Elevation of Privilege Vulnerability

Windows Print Spooler Remote Code Execution Vulnerability

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.
