A buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to improper handling of the pid parameter in the /trace.asp endpoint. This vulnerability has been classified with a CVSS base score of 7.5, indicating a high-severity risk. Organizations utilizing this firmware version should be aware of the potential implications of this flaw.
The vulnerability is particularly concerning due to its high availability impact. Attackers may leverage this flaw to cause significant disruptions in network operations, leading to potential downtime and service unavailability.
Currently, there is no known public exploit for this vulnerability, which provides a window for organizations to implement necessary mitigations. However, the lack of known exploits does not diminish the urgency for organizations to address this vulnerability, as attackers may develop methods to exploit it.
Organizations should prioritize patching immediately to safeguard their networks. Ensuring the firmware is up to date will mitigate the risks associated with this vulnerability.
Vulnerability Details
The D-Link DI-8003 firmware version 16.07.26A1 contains a buffer overflow vulnerability identified as CVE-2025-50657. The CVSS score of 7.5 indicates a high level of severity, with the vulnerability allowing network-level attacks without any required user interaction.
The official CVE description states that the vulnerability is due to improper handling of the pid parameter in the /trace.asp endpoint. This oversight can lead to a significant availability impact, which is critical for organizations relying on the affected device.
The vulnerability is classified under CWE-121, indicating a buffer error. Organizations should consult the vendor’s security bulletin for further details on the vulnerability and remediation steps.
Technical Analysis
The root cause of this vulnerability stems from inadequate input validation on the pid parameter within the /trace.asp endpoint. This flaw allows attackers to send specially crafted requests that can overflow the buffer, ultimately leading to the potential execution of arbitrary code, including denial of service.
The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it remotely without physical access to the device. The attack complexity is rated as low, requiring no special privileges or user interaction, making it accessible to a wide range of attackers.
In terms of impact, the vulnerability has no confidentiality or integrity impact, but it does pose a high availability impact. Organizations should consider the implications of this vulnerability on their operational continuity.
Risk & Impact Analysis
Risk to organizations includes potential downtime and service disruptions caused by exploitation of this vulnerability. Given the network attack vector and low attack complexity, the risk for exploitation is significant, especially for organizations with exposed D-Link devices.
The urgency for remediation is high, as the availability impact can lead to severe operational challenges. Organizations should assess their exposure and ensure that protective measures are in place to prevent exploitation.
Organizations may address this vulnerability in their priority patch cycle. The longer this vulnerability remains unpatched, the greater the risk of exploitation.
