A vulnerability was determined in UTT 进取 520W 1.7.7-180627. The impacted element is the function strcpy of the file /goform/formConfigFastDirectionW. This manipulation of the argument ssid causes buffer overflow. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
The vulnerability holds a CVSS score of 7.4, categorizing it as high severity. This level of severity indicates significant risks associated with potential exploitation. Organizations should prioritize patching immediately.
The risk to organizations includes unauthorized access and potential manipulation of the device. Attackers may leverage this vulnerability to disrupt services or gain control of the device, leading to broader network implications.
Given the exploitation status, organizations are urged to address this vulnerability in their priority patch cycle.
Vulnerability Details
The vulnerability affects the UTT 520W firmware version 1.7.7-180627. The issue arises due to improper handling of the ssid argument in the strcpy function, resulting in a buffer overflow. The vulnerability has a CVSS 3.1 score of 8.8, indicating high severity with significant confidentiality, integrity, and availability impact.
The vulnerability is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input).
The vendor's lack of response to early disclosure efforts raises concerns about the remediation timeline. Organizations using affected products should remain vigilant.
Technical Analysis
The root cause of this vulnerability is a buffer overflow due to improper handling of input data in the strcpy function. The attack vector is network-based, allowing an attacker to exploit the vulnerability remotely with low complexity and without requiring user interaction.
Exploitation requires low privileges, meaning that an attacker only needs to be a standard user to leverage this vulnerability effectively. The potential impacts include high confidentiality, integrity, and availability risks.
Risk & Impact Analysis
Organizations that deploy the affected UTT 520W firmware are at significant risk, as the buffer overflow vulnerability could lead to unauthorized access and control over the device. The blast radius of such an exploit could extend to the entire network, potentially impacting critical infrastructure.
Immediate action is necessary. Organizations should prioritize patching this vulnerability to mitigate potential attacks. The CVSS score indicates that the risk is substantial, and the lack of vendor response adds urgency to the situation.
Given the current environment, where vulnerabilities can lead to severe consequences, organizations must remain proactive in their security posture.
