TITLE

Cisco TelePresence Multipoint Switch Vulnerable to arbitrary code execution

DESCRIPTION

The Java Servlet framework on Cisco TelePresence Multipoint Switch (CTMS) devices with software 1.0.x, 1.1.x, 1.5.x, and 1.6.x does not require administrative authentication for unspecified actions, which allows remote attackers to execute arbitrary code via a crafted request, aka Bug ID CSCtf01253. The problem is Bug ID CSCtf01253 It is a problem.A third party could execute arbitrary code through a crafted request. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. To successfully exploit the vulnerability, an attacker must send a specially crafted request to the affected device TCP 80, 443 or 8080. Cisco TelePresence Multipoint Switch is prone to multiple vulnerabilities, including: 1. Multiple denial-of-service vulnerabilities 2. A security-bypass vulnerability 3. An unauthorized-access vulnerability An attacker can exploit these issues to bypass certain security restrictions and cause a denial-of-service condition. Other attacks are also possible. These issues are being tracked by the following Cisco Bug IDs: CSCtf01253 CSCtf97164 CSCth60993 CSCtj44534. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. The defect as related to each component is covered in each associated advisory. The defect as related to each component is covered in each associated advisory. The defect as related to each component is covered in each associated advisory. The defect as related to each component is covered in each associated advisory. To determine the current version of software running on the Cisco TelePresence Multipoint Switch, SSH into the device and issue the show version active and the show version inactive commands. The output should resemble the following example: admin: show version active Active Master Version: 1.7.0.0-471 Active Version Installed Software Options: No Installed Software Options Found. admin: show version inactive Inactive Master Version: 1.6.1.0-336 Inactive Version Installed Software Options: No Installed Software Options Found. In the preceding example, the system has versions 1.6.1 and 1.7.0 loaded on the device and version 1.7.0 is currently active. A device is only affected by vulnerabilities in the active software version.
