Tenda F453 Multiple Parameter Injection Flaws

Tenda F453 version 1.0.0.3 contains a stack-based buffer overflow in the SafeClientFilter parameter handler that allows authenticated remote attackers to execute arbitrary code by manipulating the manufacturer/Go argument. Public exploit code exists for this vulnerability and no patch is currently available, creating significant risk for affected deployments.

Stack-based buffer overflow in Tenda F453 firmware version 1.0.0.3 allows remote attackers to achieve complete system compromise through manipulation of the page parameter in the VirtualSer handler. Public exploit code exists for this vulnerability, and no patch is currently available. An attacker with network access can execute arbitrary code with high impact on confidentiality, integrity, and availability.

Tenda F453 1.0.0.3 contains a stack-based buffer overflow in the Natlimit parameter handler that allows authenticated remote attackers to achieve full system compromise through a malicious page argument. Public exploit code exists for this vulnerability, and no patch is currently available. An attacker with network access and valid credentials can trigger the overflow to execute arbitrary code with high integrity and confidentiality impact.

Unauthenticated attackers can execute arbitrary commands on Tenda F453 routers (version 1.0.0.3) by injecting malicious input through the mac parameter in the /goform/WriteFacMac endpoint. Public exploit code exists for this vulnerability, enabling remote code execution with minimal attack complexity. A patch is not currently available.
