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-120 | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a buffer overflow flaw found in the D-Link DIR-605L device, specifically in the function formSetMACFilter within the POST Request Handler component. The issue arises from improper handling of the argument curTime, which can be manipulated remotely to cause the buffer overflow.
Because the attack can be initiated remotely, an attacker could exploit this flaw without physical access to the device.
It is important to note that this vulnerability affects only products that are no longer supported by the maintainer.
How can this vulnerability impact me? :
Exploitation of this buffer overflow vulnerability can lead to severe impacts including unauthorized control over the affected device.
- Remote attackers may execute arbitrary code or cause a denial of service.
- Confidentiality, integrity, and availability of the device and its network communications can be compromised.
Since the device is no longer supported, no official patches or fixes are available, increasing the risk of exploitation.
What immediate steps should I take to mitigate this vulnerability?
This vulnerability affects D-Link DIR-605L 2.13B01 devices which are no longer supported by the maintainer.
Immediate mitigation steps include discontinuing use of the affected device or isolating it from untrusted networks to prevent remote exploitation.
Since no patches or updates are available, consider replacing the device with a supported model to ensure security.
