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 is a buffer overflow in the UTT HiPER 840G device firmware (up to version 3.1.1-190328). It occurs in the function accessed via the endpoint /goform/getOneApConfTempEntry, where the input parameter tempName is improperly handled. Specifically, the device copies input data without checking its size, leading to a buffer overflow condition. This flaw can be exploited remotely without authentication, potentially causing the device to crash or behave unpredictably. [1, 2]

Impact Analysis

Exploitation of this vulnerability can impact the confidentiality, integrity, and availability of the affected system. An attacker can remotely trigger the buffer overflow to cause denial of service (DoS), potentially crashing the device or disrupting its normal operation. Because the attack requires no authentication and a public exploit exists, the risk is high. This could lead to loss of control over the device or interruption of network services relying on it. [1, 2]

Detection Guidance

This vulnerability can be detected by checking if the device is running UTT HiPER 840G firmware version up to 3.1.1-190328 and by testing the endpoint /goform/getOneApConfTempEntry for buffer overflow behavior by sending crafted requests with oversized tempName parameters. Network scanning tools or custom scripts can be used to send HTTP requests to the vulnerable endpoint and observe for crashes or abnormal responses. Specific commands are not provided in the resources, but using curl or similar HTTP clients to send requests to http://<device-ip>/goform/getOneApConfTempEntry with a large tempName parameter could help detect the issue. [1, 2]

Mitigation Strategies

Immediate mitigation steps include discontinuing use of the affected UTT HiPER 840G devices running vulnerable firmware versions, as no patches or vendor mitigations are available. Network-level protections such as firewall rules to block access to the /goform/getOneApConfTempEntry endpoint or restricting remote access to the device can reduce exposure. Replacement of the affected product is recommended as a precaution. [2]
