A buffer overflow vulnerability has been identified in the Tenda F451 router, specifically in the firmware version 1.0.0.7_cn_svn7958. The issue arises in the httpd component, within the fromSafeClientFilter function of the file /goform/SafeClientFilter. The vulnerability is triggered by manipulating the menufacturer and Go parameters.
