Detailsinfo

A vulnerability was found in D-Link DIR-882 (affected version unknown). It has been rated as critical. Affected by this issue is the function sub_4455BC of the file prog.cgi of the component HTTP Handler. The manipulation of the argument IPAddress with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the `prog.cgi` and `librcm.so` binaries. The `sub_4455BC` function in `prog.cgi` stores user-supplied `SetDMZSettings/IPAddress` values in NVRAM via `nvram_safe_set("dmz_ipaddr", ...)`. These values are later retrieved in the `DMZ_run` function of `librcm.so` using `nvram_safe_get` and concatenated into `iptables` shell commands 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.

The advisory is shared for download at dlink.com. This vulnerability is handled as CVE-2025-60700 since 09/26/2025. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available. The current price for an exploit might be approx.
