The vulnerability of the getMibPrefix function (goform/formWifiFilterRulesModify) in the Tenda W20E router software allows a hacker to execute arbitrary commands.

The vulnerability of the getMibPrefix function in the microprogramming software for Tenda W20E routers stems from the operation that goes beyond the buffer in the parameter nptr’s memory. Exploiting this vulnerability allows a remote attacker to execute arbitrary commands...

CVE-2026-24113

An issue was discovered in Tenda W20E V4.0brV15.11.0.6. 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 vulnerabilit...

CVE-2026-24108

The Tenda W20E router, specifically version V4.0br_V15.11.0.6 , is vulnerable to a buffer overflow in the getMibPrefix function (associated with goform/formWifiFilterRulesAdd). The root cause is a lack of size validation when the nptr parameter is concatenated using sprintf. A remote attacker cou...
