Description
A security flaw has been discovered in Tenda F456 1.0.0.5. This affects the function frmL7ProtForm of the file /goform/L7Prot of the component httpd. Performing a manipulation of the argument page results in buffer overflow. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks.
A stack-based buffer overflow vulnerability has been identified in the Tenda F456 router, specifically in version 1.0.0.5. The issue arises in the HTTP daemon (httpd) component, within the 'frmL7ProtForm' function of the '/goform/L7Prot' file. The vulnerability is triggered by manipulating the 'page' argument, which is processed by the 'sprintf' function without proper length validation, leading to a stack overflow. This flaw allows for remote exploitation, with potential consequences including a denial-of-service condition or arbitrary code execution.
