Tenda AC18 | V15.03.05.19
How the Exploit Works
The exploit works by inputting a maliciously crafted wanMTU parameter into the fromAdvSetMacMtuWan function of the Tenda AC18’s system. This causes a stack overflow, which can lead to arbitrary code execution, potentially allowing an attacker to compromise the system and leak sensitive information.
Conceptual Example Code
The following is a conceptual example of a malicious payload that might be used to exploit this vulnerability. Note that this is a hypothetical scenario and not the actual exploit code.
POST /fromAdvSetMacMtuWan HTTP/1.1
Host: target-device-ip
Content-Type: application/json
{ "wanMTU": "maliciously_long_string_to_trigger_stack_overflow" }
In the above example, the “wanMTU” value is intentionally larger than the buffer size that the fromAdvSetMacMtuWan function can handle, leading to a stack overflow.
