CWE ID Description
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.
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).

Executive Summary

This vulnerability exists in the Tenda CH22 device, specifically in the function fromSetCfm within the /goform/setcfm file of the Parameter Handler component. It is caused by improper handling of the argument 'funcname', which leads to a stack-based buffer overflow.

Because of this flaw, an attacker can remotely exploit the device by sending specially crafted input to trigger the overflow.

The vulnerability has been publicly disclosed and can be used by attackers.

Impact Analysis

Exploitation of this vulnerability can allow a remote attacker to execute arbitrary code on the affected device due to the stack-based buffer overflow.

This can lead to compromise of the device's confidentiality, integrity, and availability.

Potential impacts include unauthorized access, disruption of device functionality, and control over the device by an attacker.
