An attacker could exploit this vulnerability by remotely connecting to the debugging tool via TCP. A successful exploit could allow the attacker to access sensitive information about the affected software or execute arbitrary code with root privileges on the affected system. This vulnerability affects Cisco Prime Data Center Network Manager (DCNM) Software Releases 10.1(1) and 10.1(2) for Microsoft Windows, Linux, and Virtual Appliance platforms. Cisco Bug IDs: CSCvd09961.

The attacker could be granted full administrator privileges. The vulnerability is due to improper implementation of authentication for accessing certain web pages using the GUI interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web interface of the affected system. A successful exploit could allow the attacker to bypass authentication and perform unauthorized configuration changes or issue control commands to the affected device. This vulnerability affects Cisco Mobility Express 1800 Series Access Points running a software version prior to 8.2.110.0. Cisco Bug IDs: CSCuy68219.

A vulnerability in a proprietary device driver in the kernel of Cisco TelePresence Multipoint Control Unit (MCU) Software could allow an unauthenticated, remote attacker to execute arbitrary code or cause a denial of service (DoS) condition. The vulnerability is due to improper size validation when reassembling fragmented IPv4 or IPv6 packets. An attacker could exploit this vulnerability by sending crafted IPv4 or IPv6 fragments to a port receiving content in Passthrough content mode. An exploit could allow the attacker to overflow a buffer. If successful, the attacker could execute arbitrary code or cause a DoS condition on the affected system. Cisco TelePresence MCU platforms TelePresence MCU 5300 Series, TelePresence MCU MSE 8510 and TelePresence MCU 4500 are affected when running software version 4.3(1.68) or later configured for Passthrough content mode.
