Cisco Small Business RV Series Confidential Information Decryption Man-in-the-Middle Vulnerability

Published: 2016-09-15 05:51:33
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:P/I:N/A:N

Detection Type:
Remote Banner

Solution Type:
Vendor Patch

Summary:
A vulnerability in the cryptographic implementation of the RV320 Dual Gigabit WAN VPN Router and the RV325 Dual Gigabit WAN VPN Router could allow an unauthenticated, remote attacker to make use of hard-coded certificate and keys embedded within the firmware of the affected device.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The vulnerability is due to the lack of unique key and certificate generation within affected appliances. This is an attack on the client attempting to access the device and does not compromise the device itself. To exploit the issue, an attacker needs not only the public and private key pair but also a privileged position in the network that would allow him or her to monitor the traffic between client and server, intercept the traffic, and modify or inject its own traffic.

Impact:
An attacker could exploit this vulnerability by using the static information to conduct man-in-the-middle attacks to decrypt confidential information on user connections.

Affected Versions:
RV320 Dual Gigabit WAN VPN Router and RV325 Dual Gigabit WAN VPN Router.

Recommendations:
Update to Firmware version 1.3.1.12

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
