CWE ID Description
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
CWE-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

Executive Summary

CVE-2025-15045 is a critical stack-based buffer overflow vulnerability in the Tenda WH450 router version 1.0.0.18. It exists in the HTTP Request Handler component, specifically in an unknown function of the file /goform/Natlimit. The vulnerability is caused by improper handling of the 'page' argument, which when manipulated with crafted input, causes a stack-based buffer overflow. This flaw can be exploited remotely without authentication, allowing attackers to potentially execute arbitrary code or cause denial of service. [2, 3]

Impact Analysis

This vulnerability can severely impact you by allowing remote attackers to exploit the router without any authentication. Successful exploitation can lead to arbitrary code execution, denial of service (DoS), and compromise of the router's confidentiality, integrity, and availability. This means attackers could take control of the device, disrupt network services, or access sensitive information. [2, 3]

Detection Guidance

This vulnerability can be detected by monitoring HTTP requests to the /goform/Natlimit endpoint of the Tenda WH450 router for unusually long or malformed 'page' parameter values that may indicate an attempted buffer overflow attack. Since the exploit involves sending crafted HTTP requests remotely, you can use network traffic analysis tools like tcpdump or Wireshark to capture and inspect HTTP requests targeting this endpoint. For example, a command to capture such traffic could be: tcpdump -i <interface> -A 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)' | grep '/goform/Natlimit'. Additionally, using curl or similar tools to send test requests with long 'page' parameters to the endpoint can help verify if the device is vulnerable. [2, 3]

Mitigation Strategies

Immediate mitigation steps include replacing the affected Tenda WH450 device with an alternative product, as there are no known countermeasures or patches currently available. Additionally, restricting remote access to the router's management interface, implementing network-level filtering to block suspicious HTTP requests to /goform/Natlimit, and monitoring for exploit attempts can help reduce risk until the device is replaced.
