CVE-2016-6265 (leap, mupdf, opensuse)
Use-after-free vulnerability in the pdf_load_xref function in pdf/pdf-xref.c in MuPDF allows remote attackers to cause a denial of service (crash) via a crafted PDF file.
CVE-2016-6322 (quickstart_cloud_installer)
Red Hat QuickStart Cloud Installer (QCI) uses world-readable permissions for /etc/qci/answers, which allows local users to obtain the root password for the deployed system by reading the file.
CVE-2016-6340 (quickstart_cloud_installer)
The kickstart file in Red Hat QuickStart Cloud Installer (QCI) forces use of MD5 passwords on deployed systems, which makes it easier for attackers to determine cleartext passwords via a brute-force attack.
CVE-2016-6525 (debian_linux, mupdf)
Heap-based buffer overflow in the pdf_load_mesh_params function in pdf/pdf-shade.c in MuPDF allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a large decode array.
CVE-2016-6669 (usg2100_firmware, usg2200_firmware, usg5100_firmware, usg5500_firmware)
Buffer overflow in the Authentication, Authorization and Accounting (AAA) module in Huawei USG2100, USG2200, USG5100, and USG5500 unified security gateways with software before V300R001C10SPC600 allows remote authenticated RADIUS servers to execute arbitrary code by sending a crafted EAP packet.
CVE-2016-6824 (ac6003_firmware, ac6005_firmware, ac6605_firmware, acu2_firmware)
Huawei AC6003, AC6005, AC6605, and ACU2 access controllers with software before V200R006C10SPC200 allows remote authenticated users to cause a denial of service (device restart) via crafted CAPWAP packets.
Kaltura Remote PHP Code Execution
This Metasploit module exploits an Object Injection vulnerability in Kaltura. By exploiting this vulnerability, unauthenticated users can execute arbitrary code under the context of the web server user. Kaltura has a module named keditorservices that takes user input and then uses it as an unserialized function parameter. The constructed object is based on the SektionEins Zend code execution POP chain PoC, with a minor modification to ensure Kaltura processes it and the Zend_Log function’s __destruct() method is called. Kaltura versions prior to 11.1.0-2 are affected by this issue. This Metasploit module was tested against Kaltura 11.1.0 installed on CentOS 6.8.
Metasploit Web UI Diagnostic Console Command Execution
This Metasploit module exploits the “diagnostic console” feature in the Metasploit Web UI to obtain a reverse shell. The diagnostic console is able to be enabled or disabled by an administrator on Metasploit Pro and by an authenticated user on Metasploit Express and Metasploit Community. When enabled, the diagnostic console provides access to msfconsole via the web interface. An authenticated user can then use the console to execute shell commands. NOTE: Valid credentials are required for this module. Tested against: Metasploit Community 4.1.0, Metasploit Community 4.8.2, Metasploit Community 4.12.0
