A vulnerability has been found in D-Link DIR-816 1.01TO and classified as problematic. This vulnerability allows for cross-site scripting (XSS) through the manipulation of the SSID argument in the file /cgi-bin/webproc?getpage=html/index.html&var:menu=24gwlan&var:page=24G_basic. The attack can be launched remotely, making it a significant risk for organizations still using this firmware. Given that this vulnerability affects products that are no longer supported by the maintainer, organizations must be particularly vigilant.
The CVSS score of 5.1 indicates a medium severity level, highlighting the importance of addressing this vulnerability promptly. Organizations should prioritize remediation efforts, especially if they are still utilizing the affected D-Link DIR-816 firmware.
Risk to organizations includes potential exploitation by attackers who may leverage this vulnerability to execute malicious scripts, compromising the integrity of user data. Furthermore, the public disclosure of the exploit increases the urgency for defenders to implement patches or workarounds.
Organizations should address in priority patch cycle, ensuring that any unsupported devices are evaluated for risks and replaced or isolated as necessary.
Vulnerability Details
The vulnerability, detailed in CVE-2025-1392, affects the D-Link DIR-816 firmware version 1.01TO. The official CVE description notes that it allows for cross-site scripting due to improper handling of user input. The CVSS base score of 5.1 classifies this vulnerability as medium severity, indicating a potential for low complexity network attacks with low privileges required and passive user interaction.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of user input in the affected web interface. Attackers may exploit this vulnerability by sending crafted requests to the device, leading to the execution of arbitrary scripts in the context of the user's browser.
The attack vector is network-based, meaning that an attacker does not need physical access to the device, which increases the likelihood of exploitation. The attack complexity is considered low, and the required privileges are also low, as the vulnerability can be exploited without requiring authentication.
User interaction is passive, meaning that a victim merely needs to visit a compromised site to trigger the exploit. The potential impact on confidentiality is none, but the integrity impact is low, as it could allow an attacker to manipulate user sessions or data.
Risk & Impact Analysis
Real-world deployment risk for this vulnerability is significant, especially for organizations that have not updated their D-Link devices. Given the nature of cross-site scripting attacks, the potential for data manipulation and unauthorized access to user sessions is considerable.
The blast radius for this vulnerability may extend to any user interacting with the affected devices, potentially leading to broader security implications if these devices are part of a larger network. Organizations should be aware of the urgency associated with this vulnerability, particularly considering the public disclosure of the exploit.
