Description
An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by controlling the value of `nptr`. When this value is passed into the `getMibPrefix` function and concatenated using `sprintf` without proper size validation, it could lead to a buffer overflow vulnerability.
