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-787 | The product writes data past the end, or before the beginning, of the intended buffer. |
| 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 is a critical stack-based buffer overflow found in the QoSPortSetup function of the D-Link DIR-816 1.10CNB05 router. It occurs due to improper handling of the arguments port0_group, port0_remarker, ssid0_group, and ssid0_remarker, allowing an attacker to remotely exploit the overflow.
How can this vulnerability impact me? :
The vulnerability can be exploited remotely to cause a stack-based buffer overflow, potentially allowing an attacker to execute arbitrary code, disrupt service, or take control of the affected device. This can lead to severe security breaches including loss of confidentiality, integrity, and availability.
What immediate steps should I take to mitigate this vulnerability?
Since the affected products are no longer supported by the maintainer, immediate mitigation steps include isolating the vulnerable device from untrusted networks, disabling remote access to the QoSPortSetup function if possible, and monitoring network traffic for suspicious activity targeting the /goform/QoSPortSetup endpoint. Consider replacing the affected device with a supported model to eliminate the risk.
