This exploit leverages both invalid typecast and memory disclosure vulnerabilities in Microsoft Silverlight 5 in order to achieve code execution. This exploit code demonstrates remote code execution by popping calc.exe. It was obtained through the Packet Storm Bug Bounty program. Google flags this as malware so only use this if you know what you are doing. The password to unarchive this zip is the word "infected".

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.

Ubuntu Security Notice 4315-1 - Maximilien Bourgeteau discovered that the Apport lock file was created with insecure permissions. This could allow a local attacker to escalate their privileges via a symlink attack. Maximilien Bourgeteau discovered a race condition in Apport when setting crash report permissions. This could allow a local attacker to read arbitrary files via a symlink attack.

Andrew Honig reported a flaw in the way KVM (Kernel-based Virtual Machine) emulated the IOAPIC. A privileged guest user could exploit this flaw to read host memory or cause a denial of service (crash the host). It was discovered that the KVM implementation in the Linux kernel, when paravirtual TLB flushes are enabled in guests, the hypervisor in some situations could miss deferred TLB flushes or otherwise mishandle them. An attacker in a guest VM could use this to expose sensitive information (read memory from another guest VM). Al Viro discovered that the vfs layer in the Linux kernel contained a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory).

Red Hat Security Advisory 2020-1449-01 - Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. A local file overwrite vulnerability was addressed.

Asterisk Project Security Advisory - The RTP support in Asterisk maintains its own registry of dynamic codecs and desired payload numbers. While an SDP negotiation may result in a codec using a different payload number these desired ones are still stored internally. When an RTP packet was received this registry would be consulted if the payload number was not found in the negotiated SDP. This registry was incorrectly consulted for all packets, even those which are dynamic. If the payload number resulted in a codec of a different type than the RTP stream (for example the payload number resulted in a video codec but the stream carried audio) a crash could occur if no stream of that type had been negotiated. This was due to the code incorrectly assuming that a stream of the type would always exist.

Ubuntu Security Notice 3939-1 - Michael Hanselmann discovered that Samba incorrectly handled registry files. A remote attacker could possibly use this issue to create new registry files outside of the share, contrary to expectations.

Red Hat Security Advisory 2019-2766-01 - Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains updated container images for multus-cni, operator-lifecycle-manager, and operator-registry in Red Hat OpenShift Container Platform 4.1.15. Each of these container images includes gRPC, which has been updated with the fixes for unbounded memory growth issues.

Trend Micro Maximum Security is vulnerable to arbitrary code execution as it allows for creation of registry key to target a process running as SYSTEM. This can allow a malware to gain elevated privileges to take over and shutdown services that require SYSTEM privileges like Trend Micros "Asmp" service "coreServiceShell.exe" which does not allow Administrators to tamper with them. This could allow an attacker or malware to gain elevated privileges and tamper with protected services by disabling or otherwise preventing them to start. Note administrator privileges are required to exploit this vulnerability.
