TITLE

Shenzhen Tenda Technology Co.,Ltd. of W20E Classic buffer overflow vulnerability in firmware

Trust: 0.8

sources: JVNDB: JVNDB-2026-005968

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. All information handled by the software may be rewritten. Furthermore, the software may stop working completely
