Publication date: 2026-04-09

Last updated on: 2026-04-30

Assigner: VulDB

Description

A vulnerability was identified in D-Link DIR-605L 2.13B01. Impacted is the function formSetLog of the file /goform/formSetLog of the component POST Request Handler. The manipulation of the argument curTime leads to buffer overflow. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. This vulnerability only affects products that are no longer supported by the maintainer.

CWE

KEV

CWE ID	Description
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-120	The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.

Attack-Flow Graph

Mitigation Strategies

This vulnerability affects D-Link DIR-605L devices that are no longer supported by the maintainer.

Immediate mitigation steps include discontinuing the 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-605L device, specifically in the function formSetLog within the POST Request Handler component. It is caused by improper handling of the argument curTime, which leads to a buffer overflow condition. This means that an attacker can send specially crafted data remotely to overflow the buffer, potentially causing unexpected behavior or allowing further exploitation.

The vulnerability is exploitable remotely and the exploit code is publicly available. However, it only affects versions of the product that are no longer supported by the manufacturer.

Impact Analysis

The buffer overflow vulnerability can lead to severe impacts including unauthorized code execution, system crashes, or denial of service on the affected device. Since the exploit is remotely executable, an attacker could potentially take control of the device or disrupt its normal operation without physical access.
