CVE-2025-15044

Comprehensive Technical Analysis of CVE-2025-15044

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-15044

Description: A stack-based buffer overflow vulnerability has been identified in Tenda WH450 firmware version 1.0.0.18. The vulnerability resides in the /goform/NatStaticSetting file, specifically in an unknown function that processes the page argument. This vulnerability allows remote attackers to exploit the system by manipulating the page argument, leading to a stack-based buffer overflow.

CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for remote exploitation, the ease of exploitability, and the severe impact on the system's confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: The vulnerability can be exploited remotely, meaning an attacker does not need physical access to the device.
• Network-Based Attacks: Given that the vulnerability is in the NAT settings, attackers can potentially exploit it through network-based attacks, such as sending crafted packets to the device.

Exploitation Methods:

• Buffer Overflow: By sending a specially crafted request with a malformed page argument, an attacker can cause a stack-based buffer overflow.
• Code Execution: The buffer overflow can lead to arbitrary code execution, allowing the attacker to take control of the device.
• Denial of Service (DoS): The overflow can also result in a crash, leading to a denial of service.

3. Affected Systems and Software Versions

Affected Systems:

• Tenda WH450 devices running firmware version 1.0.0.18.

Software Versions:
