Microsoft Silverlight 5 suffers from invalid typecast and memory disclosure vulnerabilities that, when leveraged together, allow for arbitrary code execution. A memory disclosure vulnerability exists in the public WriteableBitmap class from System.Windows.dll. This class allows reading of image pixels from the user-defined data stream via the public SetSource() method. BitmapSource.ReadStream() allocates and returns byte array and a count of array items as out parameters. These returned values are taken from the input stream and they can be fully controlled by the untrusted code. When returned "count" is greater than "array.Length", then data outside the "array" are used as input stream data by the native BitmapSource_SetSource() from agcore.dll. Later all data can be viewed via the public WriteableBitmap.Pixels[] property. Exploitation details related to these findings were purchased through the Packet Storm Bug Bounty program.

This Metasploit module exploits a vulnerability on Microsoft Silverlight. The vulnerability exists on the Initialize() method from System.Windows.Browser.ScriptObject, which access memory in an unsafe manner. Since it is accessible for untrusted code (user controlled) it's possible to dereference arbitrary memory which easily leverages to arbitrary code execution. In order to bypass DEP/ASLR a second vulnerability is used, in the public WriteableBitmap class from System.Windows.dll. This Metasploit module has been tested successfully on IE6 - IE10, Windows XP SP3 / Windows 7 SP1 on both x32 and x64 architectures.

Proof of concept code that demonstrates an ASLR bypass of PIE compiled 64bit Linux.

The release of this advisory provides exploitation details in relation a weakness in the Linux ASLR implementation. The problem appears when the executable is PIE compiled and it has an address leak belonging to the executable. These details were obtained through the Packet Storm Bug Bounty program and are being released to the community.

Microsoft Windows suffers from a Desktop Bridge Virtual Registry arbitrary file read / write privilege escalation vulnerability.

Microsoft Windows suffers from a Desktop Bridge Virtual Registry NtLoadKey arbitrary file read / write privilege escalation vulnerability.

The handling of the virtual registry for desktop bridge applications can allow an application to create arbitrary files as system resulting in privilege escalation. This is because the fix for CVE-2018-0880 (MSRC case 42755) did not cover all similar cases which were reported at the same time in the issue.

This exploit permits an attacker to bypass UAC by hijacking a registry key during computerSecurity.exe (auto elevate windows binary) execution.

This exploit modifies a windows language registry key which causes some windows binaries to stick, including login which makes the session unusable. The key is in HKCU and can be modified without admin rights, but with a bypass UAC, all user sessions can be paralyzed by using reg.exe and user's NTUSER.DAT.

The Windows registry editor allows specially crafted .reg filenames to spoof the default registry dialog warning box presented to an end user. This can potentially trick unsavvy users into choosing the wrong selection shown on the dialog box. Furthermore, we can deny the registry editor its ability to show the default secondary status dialog box (Win 10), thereby hiding the fact that our attack was successful.

The Microsoft Windows kernel's Registry Virtualization does not safely open the real key for a virtualization location leading to enumerating arbitrary keys resulting in privilege escalation.

This vulnerability allows local attackers to escalate privileges on affected installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Tracing functionality used by the Routing and Remote Access service. The issue results from the lack of proper permissions on registry keys that control this functionality. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of SYSTEM.
