Exploitability

CWE

KEV

CWE ID	Description
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).
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.

Attack-Flow Graph

Executive Summary

This vulnerability is a stack-based buffer overflow in the D-Link DIR-816L 2_06_b09_beta router. It occurs in the function scandir_main of the file /portal/__ajax_exporer.sgi when the argument 'en' is manipulated. An attacker can exploit this remotely to cause the overflow, potentially leading to arbitrary code execution or system compromise. The affected products are no longer supported by the maintainer.

Impact Analysis

Exploitation of this vulnerability can allow a remote attacker to execute arbitrary code or cause a denial of service on the affected device. This can lead to unauthorized access, disruption of network services, or compromise of the device's integrity and confidentiality.

Mitigation Strategies

Since the affected products are no longer supported by the maintainer, immediate mitigation steps include discontinuing use of the vulnerable D-Link DIR-816L 2_06_b09_beta device, isolating it from the network to prevent remote exploitation, and replacing it with a supported device that receives security updates.
