Cisco TelePresence VCS Expressway Series 8.5.2 Multiple Vulnerabilities

medium Nessus Plugin ID 85651

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version, the instance of Cisco TelePresence Video Communication Server (VCS) Expressway running on the remote host is affected by multiple vulnerabilities :

- A command injection vulnerability exists in the web framework component due to insufficient validation of user-supplied input. An authenticated, remote attacker can exploit this, via a specially crafted request, to inject arbitrary commands that execute at the 'nobody' user privilege level. (CVE-2015-4303)

- An access vulnerability exists in the Mobile and Remote Access (MRA) endpoint-validation feature due to improper validation of the phone line used for registration. An authenticated, remote attacker can exploit this, via a crafted Session Initiation Protocol (SIP) message, to register their phones and impersonate legitimate users.
(CVE-2015-4316)

- A denial of service vulnerability exists due to insufficient handling of malformed authentication messages. An unauthenticated, remote attacker can exploit this, via a crafted authentication packet with invalid variables, to cause a denial of service condition. (CVE-2015-4317)

- A denial of service vulnerability exists due to insufficient handling of malformed GET request messages.
An unauthenticated, remote attacker can exploit this, via a crafted packet with invalid variables, to cause a denial of service condition. (CVE-2015-4318)

- A security bypass vulnerability exists in the Password Change functionality due to insufficient enforcement in the authorization process. An authenticated, remote attacker can exploit this, via a specially crafted packet, to reset arbitrary active-user passwords.
(CVE-2015-4319)

- An information disclosure vulnerability exists in the Configuration Log File component due to the inclusion of sensitive information in certain log files. An authenticated, remote attacker can exploit this to view the sensitive information in the log files.
(CVE-2015-4320)
