Summary

Cisco TelePresence T, TelePresence TE, and TelePresence TC before 7.1 do not properly implement access control, which allows remote attackers to obtain root privileges by sending packets on the local network and allows physically proximate attackers to obtain root privileges via unspecified vectors, aka Bug ID CSCub67651.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Signature Spoofing by Key Theft
    An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

descriptionThe version of Cisco TelePresence TC or TE software running on the remote device is affected by one or more of the following vulnerabilities : - A implementation flaw exists in the authentication and authorization controls for internal services. An unauthenticated attacker, within the broadcast or collision domains, or who has physical access to the device, can exploit this flaw to bypass authentication and obtain root access to the system by connecting to the affected service. (CVE-2014-2174) - A flaw exists due to insufficient implementation of flood controls in the network drivers. A remote, unauthenticated attacker, by rapidly sending crafted IP packets to the device, can exploit this to cause processes to restart, potentially leading to a reload of the affected system and a denial of service.
