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 security flaw found in the D-Link DIR-619L router, specifically in the function formSchedule within the file /goform/formSchedule of the boa component. It occurs when the argument curTime is manipulated, leading to a stack-based buffer overflow. This type of flaw allows an attacker to potentially execute arbitrary code or cause a crash by sending specially crafted input.
The attack can be initiated remotely, meaning an attacker does not need physical access to the device to exploit this vulnerability.
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 vulnerability can lead to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code on the affected device.
This can result in unauthorized control over the device, potentially leading to disruption of network services, interception or manipulation of network traffic, or using the device as a foothold for further attacks within a network.
Since the attack can be performed remotely, it increases the risk of compromise without physical access.
