TOTOLINK X5000R v9.1.0u.6118B20201102 was discovered to contain a command injection vulnerability in the function NTPSyncWithHost. This vulnerability allows attackers to execute arbitrary commands via the parameter hosttime.

Command Injection in TOTOLINK X5000R router with firmware v9.1.0u.6118B20201102, and TOTOLINK A720R router with firmware v4.1.5cu.470B20200911 allows remote attackers to execute arbitrary OS commands by sending a modified HTTP request. This occurs because the function executes glibc's system function with untrusted input. In the function, "ip" parameter is directly passed to the attacker, allowing them to control the "ip" field to attack the OS.

System command injection in formDlna in TOTOLINK A3002RU version 1.0.8 allows attackers to execute system commands via the "sambaUser" POST parameter.

SYN Flood or FIN Flood attack in ECos 1 and other versions embedded devices results in web Authentication Bypass. "eCos Embedded Web Servers used by Multiple Routers and Home devices, while sending SYN Flood or FIN Flood packets fails to validate and handle the packets and does not ask for any sign of authentication resulting in Authentication Bypass. An attacker can take complete advantage of this bug and take over the device remotely or locally. The bug has been successfully tested and reproduced in some versions of SOHO Routers manufactured by TOTOLINK, GREATEK and others."
