Technical ContextAI · show details

This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. An issue was discovered on D-Link DSL-3782 EU 1.01 devices. An authenticated user can pass a long buffer as an 'unset' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'unset <node_name>' function and cause memory corruption. Furthermore, it is possible to redirect the flow of the program and execute arbitrary code. Affected products include: D-Link Dsl-3782 Firmware.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
