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-825 router, specifically in the NMBD_process function within the sserver.c file of the nmbd component. It is a buffer overflow vulnerability that can be triggered by manipulating this function.
The attack can only be initiated from within the local network, meaning an attacker must have local network access to exploit it.
The exploit for this vulnerability is publicly available, which increases the risk of it being used.
Additionally, this vulnerability affects only products that are no longer supported by the maintainer.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to a buffer overflow, which may allow an attacker to execute arbitrary code or cause a denial of service on the affected device.
Since the attack requires local network access, an attacker would need to be connected to the same network as the vulnerable device.
Successful exploitation could compromise the security and stability of the affected router, potentially impacting the entire local network.
Because the product is no longer supported, there may be no official patches or fixes available, increasing the risk.
What immediate steps should I take to mitigate this vulnerability?
The vulnerability affects D-Link DIR-825 3.00b32 and can only be exploited within the local network. Since the affected products are no longer supported by the maintainer, immediate mitigation steps include restricting local network access to the device and isolating it from untrusted users or devices.
Additionally, monitoring network traffic for suspicious activity related to the nmbd component and avoiding exposure of the device to potentially malicious local users can help reduce risk.
