VAR-202005-0074

Vulnerability from variot - Updated: 2023-12-18 14:00

This vulnerability allows network-adjacent attackers to escalate privileges on affected installations of TP-Link TL-WA855RE Firmware Ver: 855rev4-up-ver1-0-1-P1[20191213-rel60361] Wi-Fi extenders. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the first-time setup process. The issue results from the lack of proper validation on first-time setup requests. An attacker can leverage this vulnerability to reset the password for the Admin account and execute code in the context of the device. Was ZDI-CAN-10003. Zero Day Initiative To this vulnerability ZDI-CAN-10003 Was numbered.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. TP-Link TL-WA855RE is a wireless network signal extender of China TP-Link company. The vulnerability stems from the program's failure to properly verify the initial setup request

Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the first-time setup process. The issue results from the lack of proper validation on first-time setup requests. An attacker can leverage this vulnerability to reset the password for the Admin account and execute code in the context of the device. Was ZDI-CAN-10003. Zero Day Initiative To this vulnerability ZDI-CAN-10003 Was numbered.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. TP-Link TL-WA855RE is a wireless network signal extender of China TP-Link company. The vulnerability stems from the program\u0027s failure to properly verify the initial setup request",
