CWE ID Description
CWE-787 The product writes data past the end, or before the beginning, of the intended buffer.
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).

Mitigation Strategies

This vulnerability affects D-Link DIR-816 1.10CNB05 devices which are no longer supported by the maintainer.

Immediate mitigation steps include discontinuing use of the affected device or isolating it from untrusted networks to prevent remote exploitation.

Since no patches or updates are available, consider replacing the device with a supported model to ensure security.

Executive Summary

This vulnerability exists in the D-Link DIR-816 1.10CNB05 router, specifically in an unknown function within the file /goform/form2WlanBasicSetup.cgi of the goahead component.

It involves manipulation of the argument pskValue, which leads to a stack-based buffer overflow.

The vulnerability can be exploited remotely, meaning an attacker does not need local access to the device to carry out the attack.

The exploit has been publicly disclosed and may be used by attackers.

This issue affects only products that are no longer supported by the maintainer.

Impact Analysis

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.

Since the attack can be performed remotely without authentication, it poses a significant security risk.

Potential impacts include unauthorized control over the device, disruption of network services, and compromise of network security.
