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 is a stack-based buffer overflow in the authenticationcgi_main function of the /authentication.cgi file on the D-Link DIR-816L 2_06_b09_beta device. It occurs when the Password argument is manipulated, allowing an attacker to remotely exploit the device by overflowing the stack buffer.
How can this vulnerability impact me? :
The vulnerability allows remote attackers to execute arbitrary code or cause a denial of service by exploiting the stack-based buffer overflow. This can lead to full compromise of the affected device, potentially allowing unauthorized access and control.
What immediate steps should I take to mitigate this vulnerability?
Since the affected products are no longer supported by the maintainer and the exploit is public, immediate mitigation steps include isolating the vulnerable device from the network, disabling remote access to the /authentication.cgi interface if possible, and replacing the device with a supported and patched model to prevent exploitation.
