Description
A security flaw has been discovered in D-Link DI-7400G+ 19.12.25A1. Affected is the function sub_478D28 of the file /mng_platform.asp. The manipulation of the argument addr with the input `echo 12345 > poc.txt` results in command injection. An attack on the physical device is feasible. The exploit has been released to the public and may be exploited.

Executive Summary

CVE-2025-9769 is a command injection vulnerability in the D-Link DI-7400G+ router, firmware version 19.12.25A1. It occurs in the function sub_478D28 within the file /mng_platform.asp, where the input parameter 'addr' is improperly handled. This allows an attacker with physical access to the device to inject and execute arbitrary commands by manipulating this parameter, for example using payloads like `echo 12345 > poc.txt`. The vulnerability is due to the product constructing commands from external input without properly neutralizing special characters, leading to command injection. [1, 2]

Impact Analysis

This vulnerability can impact you by allowing an attacker with physical access to your D-Link DI-7400G+ router to execute arbitrary commands on the device. This compromises the confidentiality, integrity, and availability of the device, potentially leading to unauthorized control, data manipulation, or disruption of service. Since the exploit is publicly available and easy to perform, the risk is significant for affected devices. [1, 2]

Detection Guidance

Vulnerable devices can be identified by checking for the presence of the file mng_platform.asp on the D-Link DI-7400G+ router firmware version 19.12.25A1. One detection method is to search for the URL path containing 'mng_platform.asp' using Google Dorking with the query 'inurl:mng_platform.asp'. Since exploitation requires local physical access, detection on the network may be limited. There is no specific command provided for detection, but verifying the firmware version and presence of the vulnerable function can help identify affected devices. [2]

Mitigation Strategies

No known countermeasures or mitigations have been identified for this vulnerability. The suggested immediate step is to replace the affected D-Link DI-7400G+ device with an alternative product to avoid exploitation. Since the vulnerability requires physical access, restricting physical access to the device can also help mitigate risk. [2]
