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 exists in the D-Link DIR-605L device, specifically in the function formSetDDNS within the POST Request Handler component. It involves manipulation of the argument curTime, which can lead to a buffer overflow. This means that an attacker can remotely send crafted data to overflow a buffer, potentially causing unexpected behavior or allowing execution of malicious code.
The vulnerability affects only unsupported versions of the product, and the exploit has been publicly disclosed.
How can this vulnerability impact me? :
Exploiting this vulnerability can lead to a buffer overflow, which may allow an attacker to execute arbitrary code remotely on the affected device. This can result in unauthorized control over the device, disruption of its normal operation, or compromise of the network it is connected to.
What immediate steps should I take to mitigate this vulnerability?
This vulnerability affects D-Link DIR-605L devices that are no longer supported by the maintainer.
Immediate mitigation steps include discontinuing the 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 that receives security updates.
