Whitepaper called Android Security Research: Crypto Wallet Local Storage Attack.

BSidesLisbon 2019 has announced its call for papers. It will be held November 28th and 29th at Auditorio FMD-UL.

B-Sides Ljubljana will be held April 4th, 2020 in Ljubljana, Slovenia.

BSides Brussels is a security conference in Brussels, Belgium, with talks, workshops and villages. The goal is to strengthen the exchange of knowledge, cooperation, communication, and integration between the different actors active in the IT security industry. We are pleased to announce that the first edition of BSides Brussels will be held on May 28th, 2020.

This Metasploit module exploits an issue in Google Chrome version 80.0.3987.87 (64 bit). The exploit corrupts the length of a float array (float_rel), which can then be used for out of bounds read and write on adjacent memory. The relative read and write is then used to modify a UInt64Array (uint64_aarw) which is used for read and writing from absolute memory. The exploit then uses WebAssembly in order to allocate a region of RWX memory, which is then replaced with the payload shellcode. The payload is executed within the sandboxed renderer process, so the browser must be run with the --no-sandbox option for the payload to work correctly.

The HC.Server service in Hosting Controller HC10 10.14 allows an Invalid Pointer Write DoS if attackers can reach the service on port 8794. In addition this can potentially be leveraged for post exploit persistence with SYSTEM privileges, if physical access or malware is involved. If a physical attacker or malware can set its own program for the service failure recovery options, it can be used to maintain persistence. Afterwards, it can be triggered by sending a malicious request to DoS the service, which in turn can start the attackers recovery program. The attackers program can then try restarting the affected service to try an stay unnoticed by calling "sc start HCServerService". Services failure flag recovery options for "enabling actions for stops or errors" and can be set in the services "Recovery" properties tab or on the command line. Authentication is not required to reach the vulnerable service, this was tested successfully on Windows 7/10.

An elevation of privilege vulnerability exists in Microsoft Windows when the Win32k component fails to properly handle objects in memory. This affects Windows 7, Windows Server 2012 R2, Windows RT 8.1, Windows Server 2008, Windows Server 2019, Windows Server 2012, Windows 8.1, Windows Server 2016, Windows Server 2008 R2, Windows 10, Windows 10 Servers. This Metasploit module is tested against Windows 10 v1703 x86.

AVideo Platform version 8.1 suffers from a cross site request forgery vulnerability.

CandidATS version 2.1.0 suffers from a cross site request forgery vulnerability.

FreeBSD Security Advisory - The kernel driver for /dev/midistat implements a handler for read(2). This handler is not thread-safe, and a multi-threaded program can exploit races in the handler to cause it to copy out kernel memory outside the boundaries of midistat's data buffer. The races allow a program to read kernel memory within a 4GB window centered at midistat's data buffer. The buffer is allocated each time the device is opened, so an attacker is not limited to a static 4GB region of memory. On 32-bit platforms, an attempt to trigger the race may cause a page fault in kernel mode, leading to a panic.

This Metasploit module exploits a stack-based buffer overflow in the Win32AddConnection function of the VideoLAN VLC media player. Versions 0.9.9 throught 1.0.1 are reportedly affected. This vulnerability is only present in Win32 builds of VLC. This payload was found to work with the windows/exec and windows/meterpreter/reverse_tcp payloads. However, the windows/meterpreter/reverse_ord_tcp was found not to work.

This Metasploit module attempts to gain root privileges with SUID Xorg X11 server versions 1.19.0 up to 1.20.3. A permission check flaw exists for -modulepath and -logfile options when starting Xorg. This allows unprivileged users that can start the server the ability to elevate privileges and run arbitrary code under root privileges. This module has been tested with CentOS 7 (1708). CentOS default install will require console auth for the users session. Xorg must have SUID permissions and may not start if running. On successful exploitation artifacts will be created consistent with starting Xorg.

This Metasploit module exploits two vulnerabilities affecting Unraid 6.8.0. An authentication bypass is used to gain access to the administrative interface, and an insecure use of the extract PHP function can be abused for arbitrary code execution as root.
