Comprehensive Technical Analysis of EUVD-2025-202887

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability identified in UTT 进取 512W up to version 3.1.7.7-171114 involves a buffer overflow in the strcpy function within the file /goform/formConfigFastDirectionW. The manipulation of the ssid argument can lead to a buffer overflow, which can be exploited remotely.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.3, indicating a critical severity level. The CVSS vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P breaks down as follows:

• AV:N (Network): The vulnerability is exploitable over the network.
• AC:L (Low): The attack complexity is low, meaning it does not require specialized conditions.
• AT:N (None): No authentication is required to exploit the vulnerability.
• PR:N (None): No privileges are required.
• UI:N (None): No user interaction is required.
• VC:H (High): Confidentiality impact is high.
• VI:H (High): Integrity impact is high.
• VA:H (High): Availability impact is high.
• SC:N (None): The scope change is none.
• SI:N (None): The scope integrity impact is none.
• SA:N (None): The scope availability impact is none.
• E:P (Proof of Concept): An exploit is publicly available.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can exploit this vulnerability over the network without needing physical access to the device.
• Buffer Overflow: By manipulating the ssid argument, an attacker can cause a buffer overflow, leading to arbitrary code execution or denial of service.

Exploitation Methods:

• Crafted Input: An attacker can send specially crafted input to the ssid parameter, causing the strcpy function to overflow the buffer.
• Public Exploit: Given that the exploit is publicly available, attackers can use existing proof-of-concept code to target vulnerable systems.

3. Affected Systems and Software Versions

Affected Systems:

• Device: UTT 进取 512W
• Software Versions: Up to 3.1.7.7-171114
