The vulnerability has been dubbed PrintNightmare and is tracked as CVE-2021-34527. The flaw is due to the Windows Print Spooler service improperly performing privileged file operations. Microsoft says the flaw can be exploited by an authenticated user calling RpcAddPrinterDriverEx(). When exploited, an attacker gains SYSTEM privileges and can execute arbitrary code, install programs, view, change, or delete data or create new accounts with full user rights.

This module crashes the target machine producing a blue screen by sending a malformed HTTP packet.

This module uses an unauthenticated file upload vulnerability via uploadova plugin in VMware vCenter Server to upload and extract a TAR file. This TAR file contains a path traversal that allows writing files at arbitraries locations. In the vulnerable 6.5.X and 6.7.X (build 13010631 and lower) versions of VMware vCenter Server, a JSP file is deployed to gain arbitrary code execution. In the vulnerable 6.7.X (build 13643870 and greater) and 7.X versions, a file with public keys are uploaded to the vsphere-ui user home directory and then used to deploy an agent via SSH. Notice that in 6.7.X versions SSH access is disabled by default.

SolarWinds Orion is prone to a remote vulnerability that allows unauthenticated attackers to execute system commands. Using the lack of permissions that the Collector Service set on its private queues, it is possible to remotely send messages that will be deserialized allowing to execute commands as SYSTEM.

A remote code execution vulnerability exists in Windows when the DNS Server component fails to properly handle certain types of request.

This module uses an unauthenticated java deserialization vulnerability via T3 protocol in Oracle Weblogic Server to upload and execute a java class file to gain arbitrary code execution on the affected system.

Oracle WebLogic Server is prone to a remote vulnerability that allows unauthenticated attackers to execute system commands. By exploiting known methods, it is possible to remotely instantiate several java classes that allows to execute system commands.

Oracle Coherence (Caching, CacheStore and Invocation Components) is prone to a remote vulnerability that allows attackers to take advantage of a Java deserialization vulnerability. By exploiting known methods, it is possible to remotely connect to the Coherence port via T3 protocol to invoke the extract method of the ReflectionExtractor class, which allows the execution of system commands. ExtractorComparator class is used to access ReflectionExtractor class, a bypass for the original patch for CVE-2020-2555.

A remote code execution vulnerability exists when the Windows TCP/IP stack improperly handles ICMPv6 Router Advertisement packets. An attacker who successfully exploited this vulnerability could gain the ability to execute code on the target server or client. To exploit this vulnerability, an attacker would have to send specially crafted ICMPv6 Router Advertisement packets to a remote Windows computer. The update addresses the vulnerability by correcting how the Windows TCP/IP stack handles ICMPv6 Router Advertisement packets.

This module uses an unauthenticated java deserialization vulnerability via JSONWS in Liferay Portal to upload and execute a java class file to gain arbitrary code execution on the affected system.
