This vulnerability affects Tenda F451 firmware version 1.0.0.7. The fromSafeEmailFilter function improperly handles the 'page' argument, leading to a stack-based buffer overflow. This flaw allows remote attackers to potentially execute arbitrary code or cause a denial of service. The CVSS 4.0 base score is 8.7, indicating high severity with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. The vulnerability is publicly disclosed but lacks an official fix or patch at this time.

Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code on the affected device or cause it to crash, impacting confidentiality, integrity, and availability. The attack does not require user interaction or privileges, increasing its risk. However, no known active exploitation has been reported so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
