Cisco patch stops attackers from taking over TelePresence systems

Flaws were also patched in Cisco FirePOWER and Adaptive Security Appliance devices

Cisco Systems has fixed a critical vulnerability that could allow attackers to take over TelePresence systems,  and patched other high-severity flaws in Cisco FirePOWER and Adaptive Security Appliance devices.

The TelePresence software vulnerability stems from an improper authentication mechanism for the XML application programming interface (API). Attackers could exploit it by sending crafted HTTP requests to the XML API in order to bypass authentication and execute unauthorized configuration changes and commands on the system.

The vulnerability is present in the TelePresence Codec (TC) and Collaboration Endpoint (CE) software. The affected devices are: TelePresence EX Series, TelePresence Integrator C Series, TelePresence MX Series, TelePresence Profile Series, TelePresence SX Series, TelePresence SX Quick Set Series, TelePresence VX Clinical Assistant and TelePresence VX Tactical.

Users who can't immediately install the software updates can disable the XML API to mitigate this flaw, but doing so will make it impossible to manage the systems through the Cisco TelePresence Management Suite (TMS).

Otherwise, a high severity denial-of-service vulnerability was patched in the Cisco FirePOWER System Software. By exploiting the flaw, attackers could cause an affected system to stop inspecting and processing packets.

The affected products are: Cisco FirePOWER 7000 Series Appliances, Cisco FirePOWER 8000 Series Appliances, Cisco Advanced Malware Protection (AMP) for Networks running on Cisco FirePOWER 7000 Series Appliances and Cisco Advanced Malware Protection (AMP) for Networks running on Cisco FirePOWER 8000 Series Appliances.

Another denial-of-service flaw was patched in the Firepower System Software for the Adaptive Security Appliance (ASA) 5585-X FirePOWER Security Services Processor (SSP) module. By exploiting the flaw attackers could cause the Cisco FirePOWER module to cease inspecting traffic or to stop responding.

In addition to these patches, Cisco is investigating which of its products are affected by the six vulnerabilities patched this week in the OpenSSL library. The company will update its corresponding advisory when more information or patches for the affected products become available.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
