Kerentanan Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') pada tenda g1 firmware, tenda g3 firmware. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

Buffer Overflow in Tenda G1 and G3 routers with firmware v15.11.0.17(9502)_CN allows remote attackers to execute arbitrary code via a crafted action/"portMappingIndex "request. This occurs because the "formDelPortMapping" function directly passes the parameter "portMappingIndex" to strcpy without limit.
