Multiple vulnerabilities have been discovered in F5Networks products, the most severe of which could result in arbitrary code execution.

BIG-IP is a family of products covering software and hardware designed around application availability, access control, and security solutions.
Traffix SDC is a product that provides load balancing and gateway connectivity.
Big-IQ Centralized Management tracks assets and manages policies for BIG-IP products.
F5 Access for Android is an Android application that allows users to access enterprise networks and applications.
BIG-IP Guided Configuration is a products that provides a way to deploy configurations of BIP-IP APM and Advanced WAF.
The F5OS-A is the operating system software for the F5 rSeries system.
NGINX Service Mesh is a product that allows for traffic control of distributed systems.
BIG-IP APM provides access control and authentication for applications.
Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

A Vulnerability in C Standard Libraries uClibe and uClibe-ng Could Allow for DNS Poisoning

Read Time:36 Second

A vulnerability which could allow for DNS poisoning attacks has been discovered in the C standard libraries uClibe and uClibe-ng, which are widely used in IoT products. DNS poisoning enables a subsequent Man-in-the-Middle scenario, which can be used to perform actions like stealing information, forcing authenticated responses, as well as installing malicious firmware.
There is currently no CVE listing, nor further details on affected products, as the research group Nozomi Networks is still working with vendors and library developers in finding a solution.
The MS-ISAC believes that due to various mitigating factors, this vulnerability does not pose an immediate threat to our member base. We would, however, like to share relevant details for your situational awareness.
