Assigner: MITRE

Description
A stack buffer overflow vulnerability exists in the D-Link DIR-816A2 router firmware DIR-816A2_FWv1.10CNB05_R1B011D88210.img in the upload.cgi module, which handles firmware version information. The vulnerability occurs because /proc/version is read into a 512-byte buffer and then concatenated using sprintf() into another 512-byte buffer containing a 29-byte constant. Input exceeding 481 bytes triggers a stack buffer overflow, allowing an attacker who can control /proc/version content to potentially execute arbitrary code on the device.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a stack buffer overflow in the D-Link DIR-816A2 router firmware's upload.cgi module. It happens because the firmware reads the /proc/version file into a 512-byte buffer and then concatenates it into another 512-byte buffer with a 29-byte constant using sprintf(). If the input from /proc/version exceeds 481 bytes, it causes a stack buffer overflow, which can allow an attacker who controls the /proc/version content to execute arbitrary code on the device.


How can this vulnerability impact me? :

This vulnerability can allow an attacker to execute arbitrary code on the affected router device if they can control the /proc/version content. This could lead to unauthorized control over the device, potentially compromising network security, intercepting or altering network traffic, or using the device as a foothold for further attacks.
