D-Link DIR-513 | 1.0

How the Exploit Works

The vulnerability in D-Link DIR-513 1.0 is due to inadequate handling of the ‘curTime’ argument in the /goform/formSetWanPPTP file. An attacker can manipulate this argument to cause a buffer overflow, an event where more data is put into a buffer than it can handle. This overflow can overwrite other data and potentially allow the execution of arbitrary code or cause a system crash.

Conceptual Example Code

Here is a conceptual example of how this vulnerability might be exploited. Note that the following is purely hypothetical and is not an actual exploit code:
```
POST /goform/formSetWanPPTP HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
curTime=100000000000000000000000000000000000000000000000000000000000000000000000000000...
```
In this example, an excessively long ‘curTime’ value is sent to the vulnerable endpoint, potentially causing a buffer overflow.

Remediation

As the affected products are no longer supported by the manufacturer, a vendor patch is not likely to be available. As a temporary mitigation, users can implement a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to identify and block attempts to exploit this vulnerability.

Due to the overread, attacker-controlled data can be read by the application, potentially leading to information disclosure or, in some cases, remote code execution.

Conceptual Example Code

The following pseudocode demonstrates conceptually how the vulnerability might be exploited.
```
#include <stdio.h>
#include <string.h>
void vulnerable_function(char *input) {
char buffer[256];
strcpy(buffer, input); // Overread happens here with long input
printf("%s\n", buffer);
}
int main() {
char malicious_input[300];
memset(malicious_input, 'A', 299); // Fill with 'A'
malicious_input[299] = '\0'; // Null-terminate
vulnerable_function(malicious_input);
return 0;
}
```
In this example, the malicious_input string is longer than the buffer in the vulnerable_function, causing a buffer overread when the input is copied into the buffer.

Mitigation Guidance

The primary mitigation for this vulnerability is to apply the vendor patch once it’s available.
