CVE-2026-90880 Details
Description
A security flaw has been discovered in D-Link DSL-3782 2016-07-28. This issue affects the function system of the file /cgi-bin/New_GUI/Set/Diagnostics.asp of the component Diagnostics. Performing a manipulation of the argument Addr results in command injection. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks.
A command injection vulnerability has been identified in the D-Link DSL-3782 router, specifically within the Diagnostics component of the web interface. The issue arises in the '/cgi-bin/New_GUI/Set/Diagnostics.asp' file, where the 'Addr' parameter is accepted for ping and traceroute diagnostics. This parameter is passed to a 'system()' call in the backend without proper sanitization, allowing authenticated users to inject arbitrary shell commands. The vulnerability can be exploited remotely, leading to root-level command execution on the device.
D-Link has been notified of this vulnerability. Users are advised to monitor D-Link's official channels for any security updates or patches.
