Sensitive Information Disclosure

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A denial of service flaw was found in the way the Linux kernel's IPv6 implementation processed IPv6 router advertisement RA packets. An attacker able to send a large number of RA packets to a target system...

Session fixation

An issue was discovered on PHOENIX CONTACT FL NAT SMCS 8TX, FL NAT SMN 8TX, FL NAT SMN 8TX-M, and FL NAT SMN 8TX-M-DMG devices. There is unauthorized access to the WEB-UI by attackers arriving from the same source IP address as an authenticated user, because this IP address is used as a session...

Configuring Source NAT for Direct Internet Breakout on Branch SDWAN

After setting up Direct Internet Breakout DIA on a Branch Site, it can be seen that packets forwarded to the internet will retain the private IP address as the Source IP. This will result in packets not returning form public IP destinations. To resolve this, you can configure Source NAT on the...
