Vulnerability from variot

An issue was discovered on D-Link DIR-823G devices with firmware through 1.02B03. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 request. This occurs when any HNAP API function triggers a call to the system function with untrusted input from the request body, such as a body of ' /bin/telnetd' for the GetDeviceSettingsset API function. Consequently, an attacker can execute any command remotely when they control this input. D-Link DIR-823G Device firmware includes OS A command injection vulnerability exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Multiple D-Link Products are prone to a command-injection vulnerability. Failed exploit attempts will likely result in denial-of-service conditions. D-Link DIR-823G is a wireless router made by Taiwan D-Link Company. There is an operating system command injection vulnerability in D-Link DIR-823G using version 1.02B03 firmware. The vulnerability comes from the fact that the network system or product does not correctly filter special characters, commands, etc. in the process of constructing executable commands of the operating system from external input data
