CWE ID Description
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
CWE-120 The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.

Executive Summary

This vulnerability exists in the UTT 进取 520W 1.7.7-180627 device, specifically in the strcpy function within the /goform/formConfigFastDirectionW file. The issue arises from improper handling of the 'ssid' argument, which can cause a buffer overflow. This means that an attacker can remotely exploit this flaw by sending specially crafted input to overflow the buffer, potentially leading to unexpected behavior or control over the device.

Impact Analysis

The vulnerability allows remote attackers to exploit a buffer overflow, which can lead to severe impacts such as unauthorized control over the affected device, disruption of service, or execution of arbitrary code. Given the high CVSS scores (up to 9.0 in v2.0), the impact includes confidentiality, integrity, and availability compromises, meaning sensitive information could be exposed or altered, and device functionality could be disrupted.

Detection Guidance

This vulnerability can be detected by monitoring HTTP requests to the endpoint `/goform/formConfigFastDirectionW` with the `ssid` parameter containing unusually long or malformed input that could trigger a buffer overflow. Since the exploit is publicly available, you can use network traffic inspection tools like Wireshark or tcpdump to capture such requests. Additionally, sending crafted HTTP POST requests to this endpoint with oversized `ssid` values can help test if the device is vulnerable. Specific commands might include using curl to send test requests, for example: `curl -X POST http://<device-ip>/goform/formConfigFastDirectionW -d "ssid=$(python -c 'print("A"*500)')"` to check for abnormal device behavior or crashes indicating vulnerability exploitation. [2, 3]

Mitigation Strategies

There are no known patches or mitigations provided by the vendor for this vulnerability. The recommended immediate step is to replace the affected UTT 进取 520W device with an alternative product that is not vulnerable. Additionally, restricting network access to the device, such as limiting HTTP access to trusted networks only, and monitoring for exploit attempts can help reduce risk until replacement is possible. [3]

Compliance Impact

The vulnerability impacts the confidentiality, integrity, and availability of the device, which could lead to non-compliance with standards and regulations such as GDPR and HIPAA that require protection of sensitive data and system integrity. However, no specific information about compliance impact or regulatory consequences is provided in the available resources. [3]
