D-Link DIR-619L Stack-Based Buffer Overflow Vulnerability

A critical stack-based buffer overflow vulnerability has been identified in the D-Link DIR-619L router running firmware version 2.06B01. The issue arises in the 'formSetEmail' function within the file '/goform/formSetEmail'. The vulnerability can be exploited remotely by manipulating the 'curTime' and 'config.smtp_email_subject' parameters. This exploitation allows for arbitrary code execution, potentially leading to a crash of the router.

Impact

Exploitation of this vulnerability causes a stack-based buffer overflow, allowing remote attackers to execute arbitrary code on the affected device.

Reproduction

To reproduce this vulnerability, send a request to the '/goform/formSetEmail' endpoint with overly long data in the 'curTime' and 'config.smtp_email_subject' parameters. The excessive length of the input will trigger the stack-based buffer overflow.
