Vulnerabilidades de Dlink

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the `prog.cgi` and `rc` binaries. The `sub_432F60` function in `prog.cgi` stores user-supplied `SetSysLogSettings/IPAddress` values in NVRAM via `nvram_safe_set("SysLogRemote_IPAddress", ...)`. These values are later retrieved in the `sub_448DCC` function of `rc` using `nvram_safe_get` 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.

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the `prog.cgi` and `rc` binaries. The `sub_4438A4` function in `prog.cgi` stores user-supplied DDNS parameters (`ServerAddress` and `Hostname`) in NVRAM via `nvram_safe_set`. These values are later retrieved in the `start_DDNS_ipv4` function of `rc` using `nvram_safe_get` 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 weakness has been identified in D-Link DAP-2695 2.00RC13. The affected element is the function sub_40C6B8 of the component Firmware Update Handler. Executing manipulation can lead to improper verification of cryptographic signature. The attack can be launched remotely. Attacks of this nature are highly complex. The exploitability is described as difficult. The exploit has been made available to the public and could be exploited. This vulnerability only affects products that are no longer supported by the maintainer.
