Overview
A significant Server-Side Request Forgery (SSRF) vulnerability has been identified in Salesforce’s Tableau Server – a popular data visualization tool. With a CVSS severity score of 8.2, this vulnerability is a major concern. It affects both Windows and Linux versions of the server, specifically targeting the Flow Data Source modules. The implications of this vulnerability are severe, including potential system compromise or data leakage, making it a pressing concern for any organization utilizing these affected systems.
The SSRF vulnerability allows an attacker to spoof the server’s resource location, which could potentially grant unauthorized access to internal resources, bypassing standard security measures. The importance of addressing this vulnerability cannot be overstated due to the potential risk posed to sensitive business data.

How the Exploit Works
The SSRF vulnerability in Salesforce Tableau Server takes advantage of the Flow Data Source modules’ ability to make requests to internal resources. An attacker can craft malicious requests which masquerade as legitimate server requests. This allows the attacker to bypass security measures and access sensitive internal resources, potentially leading to system compromise or data leakage.
Conceptual Example Code
An attacker might exploit the vulnerability by sending a HTTP request similar to the following:
GET /flow-data-source/module HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "resource_location": "internal://sensitive-data" }This request would trick the server into believing that it is a legitimate request for internal resources, thus enabling the attacker to access sensitive data or systems.
Mitigation and Prevention
To mitigate the impact of this vulnerability, users are advised to apply the vendor patch as soon as it is available. For immediate mitigation, users can employ a Web Application Firewall (WAF) or an Intrusion Detection System (IDS). These systems can detect and block SSRF attempts, providing temporary mitigation until the patch is installed. Regular security audits and updates can also help in preventing such vulnerabilities from being exploited.
