How the Exploit Works
The vulnerability lies within a specific argument (remoteSrcTemp) of the /goform/aspRemoteApConfTempSend file. The manipulation of this argument can lead to a buffer overflow condition. Buffer overflow occurs when more data is written into a buffer than it can handle, causing an overflow of data into adjacent memory, which could potentially lead to arbitrary code execution or denial of service.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This is a basic HTTP POST request, which includes a malicious payload that could manipulate the “remoteSrcTemp” argument, causing a buffer overflow.
POST /goform/aspRemoteApConfTempSend HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
remoteSrcTemp=AAAAA...[Add large amount of A's to overflow buffer]...AAAAAMitigation
There is currently no patch provided by the vendor for this vulnerability. As a mitigation measure, it is recommended to utilize a Web Application Firewall (WAF) or Intrusion Detection Systems (IDS). These can help detect and block attempts to exploit this vulnerability. However, it is advised to continue monitoring any updates from the vendor regarding a potential patch.
