Description

A buffer overflow vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the `global.so` binary. The `getSaveConfig` function retrieves the `http_host` parameter from user input via `websGetVar` and copies it into a fixed-size stack buffer (`v13`) using `strcpy()` without performing any length checks. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted HTTP request to the router's web interface, potentially leading to arbitrary code execution.

CWE ID	Description
CWE-121	A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

Attack-Flow Graph

Executive Summary

This vulnerability is a buffer overflow in the TOTOLINK A950RG Router firmware. Specifically, in the 'global.so' binary, the 'getSaveConfig' function copies user-supplied 'http_host' data into a fixed-size buffer without checking its length. An unauthenticated remote attacker can send a specially crafted HTTP request to exploit this flaw, potentially causing arbitrary code execution on the router.

Impact Analysis

Exploiting this vulnerability can allow an unauthenticated remote attacker to execute arbitrary code on the affected router. This could lead to full compromise of the device, unauthorized access to network traffic, disruption of network services, or use of the router as a foothold for further attacks within the network.
