A vulnerability related to the use an insecure Platform Key (PK) has been discovered. An attacker with the compromised PK private key can create malicious UEFI software that is signed with a trusted key that has been compromised.

A denial-of-service issue was discovered on certain GL-iNet devices. Some websites can detect devices exposed to the external network through DDNS, and consequently obtain the IP addresses and ports of devices that are exposed. By using special usernames and special characters (such as half parentheses or square brackets), one can call the login interface and cause the session-management program to crash, resulting in customers being unable to log into their devices. This affects MT6000 4.5.6, XE3000 4.4.5, X3000 4.4.6, MT3000 4.5.0, MT2500 4.5.0, AXT1800 4.5.0, AX1800 4.5.0, A1300 4.5.0, S200 4.1.4-0300, X750 4.3.7, SFT1200 4.3.7, MT1300 4.3.10, AR750 4.3.10, AR750S 4.3.10, AR300M 4.3.10, AR300M16 4.3.10, B1300 4.3.10, MT300N-V2 4.3.10, and XE300 4.3.16.

An issue in GL-iNet products AR750/AR750S/AR300M/AR300M16/MT300N-V2/B1300/MT1300/SFT1200/X750 v4.3.11, MT3000/MT2500/AXT1800/AX1800/A1300/X300B v4.5.16, XE300 v4.3.16, E750 v4.3.12, AP1300/S1300 v4.3.13, XE3000/X3000 v4, and B2200/MV1000/MV1000W/USB150/N300/SF1200 v3.216 allows attackers to intercept communications via a man-in-the-middle attack when DDNS clients are reporting data to the server.

Certain models of D-Link wireless routers contain an undisclosed factory testing backdoor. Unauthenticated attackers on the local area network can force the device to enable Telnet service by accessing a specific URL and can log in by using the administrator credentials obtained from analyzing the firmware.

Certain models of D-Link wireless routers have a path traversal vulnerability. Unauthenticated attackers on the same local area network can read arbitrary system files by manipulating the URL.

NETGEAR RAX30 SOAP Request SQL Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of specific SOAP requests. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the service account. Was ZDI-CAN-19754.
