VAR-202108-1372

Vulnerability from variot - Updated: 2023-12-18 11:57

An issue was discovered in D-Link DIR-816 DIR-816A2_FWv1.10CNB05_R1B011D88210 The HTTP request parameter is used in the handler function of /goform/form2userconfig.cgi route, which can construct the user name string to delete the user function. This can lead to command injection through shell metacharacters. D-Link DIR-816 DIR-816A2_FW Contains a command injection vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. D-Link DIR-816 is a wireless router made by D-Link in Taiwan.

D-Link DIR-816 has a security vulnerability, which can be exploited by attackers to execute arbitrary php code through the typename parameter
