CVE-2025-14535

Comprehensive Technical Analysis of CVE-2025-14535

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-14535 CVSS Score: 9.8

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 is a critical issue due to its potential for remote exploitation. The high CVSS score of 9.8 indicates a severe vulnerability that poses significant risk.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: The vulnerability can be exploited remotely, making it a high-risk target for attackers.
• Network-Based Attacks: Given the nature of the ssid parameter, which is typically associated with wireless configurations, attackers could exploit this vulnerability over the network.

Exploitation Methods:

• Buffer Overflow: By sending a specially crafted ssid value, an attacker can cause a buffer overflow in the strcpy function.
• Code Execution: The buffer overflow can potentially lead to arbitrary code execution, allowing attackers to gain control over the affected device.
• Denial of Service (DoS): Even if code execution is not achieved, the buffer overflow can cause the device to crash, resulting in a DoS condition.

3. Affected Systems and Software Versions

Affected Systems:

• UTT 进取 512W devices running firmware versions up to 3.1.7.7-171114.

Software Versions:

• All versions up to and including 3.1.7.7-171114 are affected.

4. Recommended Mitigation Strategies

Immediate Actions:
