Chrome 72.0.3626.119 FileReader Use-After-Free
This exploit takes advantage of a use after free vulnerability in Google Chrome 72.0.3626.119 running on Windows 7 x86. The FileReader.readAsArrayBuffer function can return multiple references to the same ArrayBuffer object, which can be freed and overwritten with sprayed objects. The dangling ArrayBuffer reference can be used to access the sprayed objects, allowing arbitrary memory access from Javascript. This is used to write and execute shellcode in a WebAssembly object. The shellcode is executed within the Chrome sandbox, so you must explicitly disable the sandbox for the payload to be successful. [ + ]

PostgreSQL COPY FROM PROGRAM Command Execution
Installations running Postgres 9.3 and above have functionality which allows for the superuser and users with 'pg_execute_server_program' to pipe to and from an external program using COPY. This allows arbitrary command execution as though you have console access. This module attempts to create a new table, then execute system commands in the context of copying the command output into the table. This Metasploit module should work on all Postgres systems running version 9.3 and above. For Linux and OSX systems, target 1 is used with cmd payloads such as: cmd/unix/reverse_perl. For Windows Systems, target 2 is used with powershell payloads such as: cmd/windows/powershell_reverse_tcp. Alternatively target 3 can be used to execute generic commands, such as a web_delivery meterpreter powershell payload or other customized command. [ + ]

Windows PowerShell ISE / Filename Parsing Flaw Remote Code Execution
Microsoft Windows PowerShell ISE will execute wrongly supplied code when debugging specially crafted PowerShell scripts that contain array brackets as part of the filename. This can result in ISE executing attacker supplied scripts pointed to by the filename and not the "trusted" PS file currently loaded and being viewed by a user in the host application. This undermines the integrity of PowerShell ISE allowing potential unexpected remote code execution. [ + ]

Atlassian Confluence Widget Connector Macro Velocity Template Injection
Widget Connector Macro is part of Atlassian Confluence Server and Data Center that allows embed online videos, slideshows, photostreams and more directly into page. A _template parameter can be used to inject remote Java code into a Velocity template, and gain code execution. Authentication is not required to exploit this vulnerability. By default, Java payload will be used because it is cross-platform, but you can also specify which native payload you want (Linux or Windows). Confluence before version 6.6.12, from version 6.7.0 before 6.12.3, from version 6.13.0 before 6.13.3 and from version 6.14.0 before 6.14.2 are affected. [ + ]

Microsoft Windows LUAFV PostLuafvPostReadWrite SECTION_OBJECT_POINTERS Race Condition
On Microsoft Windows, the LUAFV driver has a race condition in the LuafvPostReadWrite callback if delay virtualization has occurred during a read leading to the SECTION_OBJECT_POINTERS value being reset to the underlying file resulting in elevation of privilege. [ + ]

Microsoft Windows LUAFV Delayed Virtualization Cache Manager Poisoning Privilege Escalation
On Microsoft Windows, the LUAFV driver can confuse the cache and memory manager to replace the contents of privileged file leading to elevation of privilege. [ + ]

Microsoft Windows LUAFV NtSetCachedSigningLevel Device Guard Bypass
On Microsoft Windows, the NtSetCachedSigningLevel system call can be tricked by the operation of LUAFV to apply a cached signature to an arbitrary file leading to a bypass of code signing enforcement under UMCI with Device Guard. [ + ]

Microsoft Windows LUAFV LuafvCopyShortName Arbitrary Short Name Privilege Escalation
On Microsoft Windows, the LUAFV driver bypasses security checks to copy short names during file virtualization which can be tricked into writing an arbitrary short name leading to elevation of privilege. [ + ]

Microsoft Windows LUAFV Delayed Virtualization Cross Process Handle Duplication Privilege Escalation
On Microsoft Windows, the LUAFV driver doesn't take into account a virtualized handle being duplicated to a more privileged process resulting in elevation of privilege. [ + ]

Microsoft Windows LUAFV Delayed Virtualization MAXIMUM_ACCESS DesiredAccess Privilege Escalation
On Microsoft Windows, the LUAFV driver reuses the file's create request DesiredAccess parameter, which can include MAXIMUM_ACCESS, when virtualizing a file resulting in elevation of privilege. [ + ]

Microsoft Windows CSRSS SxSSrv Cached Manifest Privilege Escalation
On Microsoft Windows, the SxS manifest cache in CSRSS uses a weak key allowing an attacker to fill a cache entry for a system binary leading to elevation of privilege. [ + ]

Microsoft Windows Contact File Format Arbitary Code Execution
This Metasploit module allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The flaw is due to processing of contact files. [ + ]
