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-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

Executive Summary

This vulnerability is a stack-based buffer overflow in the Tenda AC7 router firmware version 15.03.06.44. It occurs in the handling of the 'newVersion' parameter within the POST request to the /goform/setNotUpgrade endpoint. Improper bounds checking allows an attacker to overflow the stack buffer by manipulating this parameter, potentially leading to arbitrary code execution or denial of service on the device. The vulnerability can be exploited remotely without local access. [2, 3]

Impact Analysis

Exploiting this vulnerability could allow an attacker to execute arbitrary code or cause a denial of service on the affected Tenda AC7 router. This compromises the confidentiality, integrity, and availability of the device, potentially allowing unauthorized control or disruption of network services. [2, 3]

Detection Guidance

This vulnerability can be detected by monitoring or testing for POST requests to the /goform/setNotUpgrade endpoint with the newVersion parameter. Since the exploit is publicly available, one could use the proof-of-concept exploit from the referenced GitHub repository to test the device. Specific detection commands are not provided in the resources. [1, 2, 3]

Mitigation Strategies

No known mitigations or countermeasures have been identified for this vulnerability. The suggested immediate step is to replace the affected Tenda AC7 device with an alternative product to avoid exploitation. [3]
