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-2025-10432 is a critical stack-based buffer overflow vulnerability in the Tenda AC1206 router firmware version 15.03.06.23. It exists in the HTTP Request Handler component, specifically in the function check_param_changed at the /goform/AdvSetMacMtuWa endpoint. The vulnerability occurs due to improper handling and insufficient bounds checking of the wanMTU argument, allowing an attacker to cause a stack-based buffer overflow remotely without authentication. This flaw can compromise the router's confidentiality, integrity, and availability. [1, 2]

Impact Analysis

This vulnerability can be exploited remotely by an unauthenticated attacker to cause a stack-based buffer overflow, potentially leading to remote code execution (RCE) or a denial of service (DoS) attack on the affected router. This means an attacker could take control of the device, disrupt its operation, or compromise the network it serves, impacting confidentiality, integrity, and availability of network communications. [1, 2]

Detection Guidance

This vulnerability can be detected by monitoring HTTP requests targeting the /goform/AdvSetMacMtuWa or /goform/AdvSetMacMtuWan endpoints for unusual or malicious manipulation of the wanMTU parameter. Since the exploit involves sending crafted HTTP requests to these endpoints, network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to log or alert on such requests. Specific commands to detect this might include using tools like curl or wget to test the endpoint with crafted parameters, or using network packet capture tools like tcpdump or Wireshark to monitor traffic for suspicious requests. For example, a curl command to test might be: curl -v "http://<router-ip>/goform/AdvSetMacMtuWa" -d "wanMTU=malicious_payload". However, no specific detection commands or signatures are provided in the resources. [1, 2]

Mitigation Strategies

There are no known mitigations or countermeasures currently available for this vulnerability. The recommended immediate step is to replace the affected Tenda AC1206 device with an alternative product that is not vulnerable. Additionally, restricting network access to the device, such as limiting exposure to untrusted networks and monitoring for exploit attempts, may reduce risk temporarily until replacement is possible.
