New Critical Vulnerabilities Affecting F5’s BIG-IP Networking Devices
Threat Level Description
Threat Level: High - An attack is highly likely. Additional and sustainable protective security measures reflecting the broad nature of the threat combined with specific business and geographical vulnerabilities and judgments on acceptable risk.
We have observed that two new critical vulnerabilities affecting F5’s BIG-IP networking devices, have been identified.
The first vulnerability (CVE-2020-5902) resides in a configuration utility, called Traffic Management User Interface (TMUI), for BIG-IP application delivery controller (ADC), and could let remote attackers take complete control of the targeted systems, eventually gaining surveillance over the application data they manage.
BIG-IP ADC is being used by enterprises, data centers, and cloud computing environments, allowing them to implement application acceleration, load balancing, rate shaping, SSL offloading, and web application firewall services.
An unauthenticated remote attacker could exploit this vulnerability by sending a maliciously crafted HTTP request to the targeted server, hosting the Traffic Management User Interface (TMUI) utility for BIG-IP configuration.
BASE SCORE: 10 High
In BIG-IP versions 15.0.0-22.214.171.124, 14.1.0-126.96.36.199, 13.1.0-188.8.131.52, 12.1.0-184.108.40.206, and 11.6.1-220.127.116.11, the Traffic Management User Interface (TMUI), also referred to as the Configuration utility, has a Remote Code Execution (RCE) vulnerability in undisclosed pages.
BASE SCORE: 4.3 Medium
In BIG-IP versions 15.0.0-18.104.22.168, 14.1.0-22.214.171.124, 13.1.0-126.96.36.199, 12.1.0-188.8.131.52, a Cross-Site Scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility.
