CVE-2020-28041

The SIP ALG implementation on NETGEAR Nighthawk R7000 1.0.9.6410.2.64 devices allows remote attackers to communicate with arbitrary TCP and UDP services on a victim's intranet machine, if the victim visits an attacker-controlled web site with a modern browser, aka NAT Slipstreaming. This occurs...

New NAT/Firewall Bypass Attack Lets Hackers Access Any TCP/UDP Service

A new research has demonstrated a technique that allows an attacker to bypass firewall protection and remotely access any TCP/UDP service on a victim machine. Called NAT Slipstreaming, the method involves sending the target a link to a malicious site or a legitimate site loaded with malicious ads...

CVE-2020-24990

The CVE-2020-24990 issue affects QSC Q-SYS Core Manager 8.2.1 via the TFTP service on UDP/69, enabling a directory traversal to read OS files (e.g., /etc/passwd, /proc/version). Root cause: TFTP GET requests bypass path filtering. Impact is partial confidentiality loss without integrity/availabil...

CVE-2020-24990

An issue was discovered in QSC Q-SYS Core Manager 8.2.1. By utilizing the TFTP service running on UDP port 69, a remote attacker can perform a directory traversal and obtain operating system files via a TFTP GET request, as demonstrated by reading /etc/passwd or /proc/version...
