Exploitability
| 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). |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Edimax EW-7438RPn device, specifically in the function formSDHCP located in the file /goform/formSDHCP. It involves manipulation of the argument submit-url, which leads to a stack-based buffer overflow. This type of vulnerability allows an attacker to overwrite parts of the memory stack, potentially enabling remote code execution or other malicious actions.
The attack can be launched remotely, meaning an attacker does not need physical access to the device to exploit this vulnerability.
The exploit has been publicly disclosed, and the vendor was contacted but did not respond.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code on the affected device remotely.
This can result in unauthorized control over the device, potentially leading to data theft, disruption of network services, or using the device as a foothold for further attacks within a network.
Given the high CVSS scores (up to 9.0 in version 2.0), the impact is considered severe.
