How the Exploit Works
The vulnerability arises from the insecure permissions associated with the Local Storage feature in Alteryx Server 2023.1.1.460. Remote attackers can exploit these insecure permissions to gain unauthorized access to valid user session tokens stored in the localStorage. Once these tokens are obtained, they can be used to authenticate the attacker’s session as a legitimate user, effectively leading to account takeover. Furthermore, with access to a legitimate user’s account, the attacker could potentially compromise the system or leak sensitive data.
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.comUpon 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. Regular reviews of system logs and active monitoring for any unusual activity can also help in early detection of any potential exploit attempts.
