1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-44884 CISA Vulnerability Name: CVE-2025-44884 Description: FW-WGS-804HPT v1.305b241111 was discovered to contain a stack overflow via the web_sys_infoContact_post function. CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is likely due to the potential for remote code execution, the ease of exploitation, and the significant impact on the affected system's confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker could exploit this vulnerability over the network by sending crafted HTTP POST requests to the web_sys_infoContact_post function.
• Phishing: An attacker could trick a user into visiting a malicious website that sends the crafted request to the vulnerable system.

Exploitation Methods:

• Buffer Overflow: The attacker can send a specially crafted payload that exceeds the buffer size allocated for the web_sys_infoContact_post function, leading to a stack overflow.
• Code Execution: By carefully crafting the payload, the attacker can overwrite the return address on the stack, leading to arbitrary code execution.

3. Affected Systems and Software Versions

Affected Systems:

• Devices running FW-WGS-804HPT firmware version v1.305b241111.

Software Versions:

• FW-WGS-804HPT v1.305b241111

Vulnerability Details:

• Function: web_sys_infoContact_post
• Type: Stack Overflow
• Trigger: Crafted HTTP POST request

Exploitation Steps:

1. Identify Target: Locate devices running FW-WGS-804HPT v1.305b241111.
2. Craft Payload: Create a payload that exceeds the buffer size for the web_sys_infoContact_post function.
3. Send Request: Send the crafted HTTP POST request to the target device.
4. Execute Code: Overwrite the return address to execute arbitrary code.

Detection Methods:

• Log Analysis: Monitor logs for unusual HTTP POST requests to the web_sys_infoContact_post function.
• Anomaly Detection: Use anomaly detection tools to identify abnormal network traffic patterns.

Mitigation Tools:

• Web Application Firewalls (WAF): Deploy WAFs to filter out malicious HTTP requests.
• Patch Management: Implement a robust patch management system to ensure timely updates.

Conclusion: CVE-2025-44884 represents a critical vulnerability that requires immediate attention.
