A stack buffer overflow vulnerability exists in the D-Link DIR-816A2 router firmware DIR-816A2FWv1.10CNB05R1B011D88210.img in the upload.cgi module, which handles firmware version information. The vulnerability occurs because /proc/version is read into a 512-byte buffer and then concatenated using sprintf() into another 512-byte buffer containing a 29-byte constant. Input exceeding 481 bytes triggers a stack buffer overflow, allowing an attacker who can control /proc/version content to potentially execute arbitrary code on the device.

D-Link DSL-124 ME1.00 contains a configuration file disclosure vulnerability that allows unauthenticated attackers to retrieve router settings through a POST request. Attackers can send a specific POST request to the router's configuration endpoint to download a complete backup file containing sensitive network credentials and system configurations.

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1FW102B02 within the prog.cgi and rc binaries. The sub4438A4 function in prog.cgi stores user-supplied DDNS parameters (ServerAddress and Hostname) in NVRAM via nvramsafeset. These values are later retrieved in the startDDNSipv4 function of rc using nvramsafeget and concatenated into DDNS shell commands executed via twsystem() without proper sanitization. Partial string comparison is performed but is insufficient to prevent command injection. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1FW102B02 within the prog.cgi and rc binaries. The sub432F60 function in prog.cgi stores user-supplied SetSysLogSettings/IPAddress values in NVRAM via nvramsafeset("SysLogRemoteIPAddress", ...). These values are later retrieved in the sub448DCC function of rc using nvramsafeget and concatenated into a shell command executed via twsystem() without any sanitization. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.
