VAR-202510-0243

Vulnerability from variot - Updated: 2025-11-22 23:12

A vulnerability was found in Tenda CH22 1.0.0.1. This affects the function formSafeEmailFilter of the file /goform/SafeEmailFilter. Performing manipulation of the argument page results in memory corruption. The attack is possible to be carried out remotely. The exploit has been made public and could be used. of ch22 A buffer error vulnerability exists in the firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability stems from the failure of the formSafeEmailFilter function in the file /goform/SafeEmailFilter to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
