CWE ID Description
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.
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.

Executive Summary

This is a buffer overflow vulnerability in the UTT HiPER 1200GW router firmware up to version 2.5.3-170306. It occurs in the strcpy function of the /goform/formConfigFastDirectionW endpoint when the ssid parameter is manipulated. An attacker can send a crafted POST request with an excessively long ssid value, causing a buffer overflow that may lead to denial of service or other malicious actions.

Detection Guidance

To detect this vulnerability, monitor network traffic for POST requests to /goform/formConfigFastDirectionW with a long ssid parameter. Check if the wrlessMode parameter is set to 4. Use tools like Wireshark or tcpdump to capture and analyze HTTP POST requests targeting this endpoint.

Impact Analysis

If exploited, this vulnerability could allow remote attackers to crash the router or execute arbitrary code, potentially leading to loss of network connectivity or unauthorized access to the device. Users with vulnerable firmware versions should update immediately to mitigate risks.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR or HIPAA as it is a technical flaw in a router's firmware. However, if exploited, it could lead to unauthorized access or data breaches, which may indirectly impact compliance with these regulations depending on the data processed by the affected device.

Mitigation Strategies

Immediately update the UTT HiPER 1200GW firmware to the latest version beyond v2.5.3-170306. Disable remote access to the router's web interface if not required. Block external requests to /goform/formConfigFastDirectionW at the network firewall level.
