A buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to improper handling of multiple parameters in the /url_rule.asp endpoint. An attacker can exploit this vulnerability by sending a crafted HTTP GET request with parameters name, en, ips, u, time, act, rpri, and log. The CVSS score for this vulnerability is 7.5, classified as high severity, indicating significant concern for affected systems.
Risk to organizations includes potential unauthorized access and significant disruption due to the availability impact being rated as high. Given the high CVSS score, organizations should prioritize patching immediately.
As of now, there are no confirmed public exploits, and the vulnerability is not included in the Known Exploited Vulnerabilities (KEV) list. However, the presence of the vulnerability in a widely used product raises the potential for future exploitation.
Organizations using D-Link DI-8003 firmware version 16.07.26A1 should take immediate action to implement necessary patches and security measures.
Vulnerability Details
The D-Link DI-8003 firmware version 16.07.26A1 contains a buffer overflow vulnerability that arises from improper parameter handling on the /url_rule.asp endpoint. The vulnerability is classified under CWE-121.
The CVSS 3.1 vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating a network attack vector with low attack complexity and no privileges or user interaction required for exploitation.
Technical Analysis
The root cause of the vulnerability stems from inadequate validation of input parameters, which can lead to a buffer overflow. Attackers may exploit this by sending specially crafted HTTP GET requests that manipulate the parameters.
The attack vector is network-based, requiring no special privileges or user interaction, making it easier for attackers to target vulnerable systems. The impact on availability is rated high, indicating that exploitation may render the device inoperative.
Risk & Impact Analysis
The real-world risk posed by this vulnerability is considerable, especially for organizations relying on D-Link DI-8003 devices in critical infrastructure. The potential blast radius, if exploited, could lead to widespread service disruption.
Given the high severity and the potential for exploitation, organizations should assess their exposure and prioritize remediation efforts. The CVSS score of 7.5 underscores the urgency of addressing this vulnerability.
