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).
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

Executive Summary

This vulnerability exists in the TOTOLINK A3300R router firmware version 17.0.0cu.557_B20221024, specifically in the setSyslogCfg function of the /cgi-bin/cstecgi.cgi file's POST Parameter Handler. It is a stack-based buffer overflow caused by improper manipulation of the 'enable' argument. An attacker can exploit this remotely to potentially execute arbitrary code or cause a denial of service. [1]

Impact Analysis

The vulnerability can allow a remote attacker to perform a stack-based buffer overflow, which may lead to arbitrary code execution or denial of service on the affected device. This can compromise the security and availability of the router, potentially allowing attackers to control network traffic or disrupt network services. [1]
