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

Trust: 0.8

sources: JVNDB: JVNDB-2026-005969

DESCRIPTION

An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by specifying the value of `userInfo`. When `userInfo` is passed into the `addWewifiWhiteUser` function and processed by `sscanf` without 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
