Received Received - Intake
Buffer Overflow in D-Link miniupnpd AddPortMapping Function

Publication date: 2026-04-27

Last updated on: 2026-04-30

Assigner: VulDB

Description
A security flaw has been discovered in D-Link DIR-825 up to 3.00b32. This impacts the function AddPortMapping of the file upnpsoap.c of the component miniupnpd. Performing a manipulation of the argument NewPortMappingDescription results in buffer overflow. The attack needs to be approached within the local network. The exploit has been released to the public and may be used for attacks. This vulnerability only affects products that are no longer supported by the maintainer.

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.

Impact Analysis

Exploiting this vulnerability can lead to a buffer overflow, which may allow an attacker within the local network to execute arbitrary code or cause a denial of service on the affected device. This can compromise the security and availability of the router, potentially allowing attackers to intercept or manipulate network traffic.

Executive Summary

This vulnerability is a security flaw found in the D-Link DIR-825 router up to firmware version 3.00b32. It affects the AddPortMapping function in the miniupnpd component, specifically in the file upnpsoap.c. The flaw occurs when the argument NewPortMappingDescription is manipulated, causing a buffer overflow. Exploiting this vulnerability requires access to the local network.

The vulnerability has been publicly disclosed and an exploit is available, which means attackers can use it to compromise affected devices. However, it only impacts products that are no longer supported by the manufacturer.

Mitigation Strategies

This vulnerability affects D-Link DIR-825 devices up to firmware version 3.00b32 and involves a buffer overflow in the AddPortMapping function of miniupnpd. Since the affected products are no longer supported by the maintainer, no official patches are available.

Immediate mitigation steps include restricting access to the local network where the device resides, disabling UPnP services if possible, and isolating the vulnerable device from untrusted users or networks to prevent exploitation.
