Affected Products

Product | Affected Versions

Tenda O3V2 | 1.0.0.12(3880)

How the Exploit Works

The vulnerability lies in the manipulation of the ‘destIP’ argument in the fromSpeedTestSet function of /goform/setRateTest file. This improper input validation allows a remote attacker to trigger a stack-based buffer overflow, which can lead to arbitrary code execution. In other words, the attacker can manipulate the system as they wish, which can lead to unauthorized access, data leakage, or even total system compromise.

Conceptual Example Code

Consider the following conceptual HTTP request exploiting this vulnerability:

POST /goform/setRateTest HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
destIP=127.0.0.1%00{malicious_shellcode}

This request sends an overly long ‘destIP’ argument filled with the attacker’s malicious shellcode to the vulnerable endpoint. The ‘%00’ acts as a null terminator, effectively causing a buffer overflow and making the system execute the malicious shellcode.

Mitigation Guidance

Tenda should release a vendor patch to address this vulnerability. In the meantime, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. These tools can detect and block malicious traffic attempting to exploit this vulnerability. Users are urged to apply the vendor patch as soon as it becomes available and regularly update their systems to protect against such vulnerabilities.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This example is oversimplified but serves to illustrate the potential attack. The attacker intercepts the network traffic and sends a malicious HTTP request to the server to retrieve the user’s session token:

GET /localStorage/sessionToken HTTP/1.1
Host: vulnerableAlteryxServer.com

Upon receiving the HTTP request, the server retrieves and sends the session token to the attacker, who then uses it to authenticate their session:

POST /login HTTP/1.1
Host: vulnerableAlteryxServer.com
Content-Type: application/json
{ "session_token": "stolen_token" }

Mitigation Guidance

Users of Alteryx Server version 2023.1.1.460 are strongly recommended to apply the vendor’s patch to rectify this vulnerability. In cases where patch deployment is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure by detecting and blocking malicious activity.
