How the Exploit Works

The vulnerability stems from an improper limitation of a pathname to a restricted directory (‘Path Traversal‘) in the Salesforce Tableau Server. This is due to inadequate input validation in the ‘tabdoc api – duplicate-data-source’ modules. An attacker can exploit this vulnerability by sending specially crafted requests to the server, tricking it into accessing files or directories that are outside the intended restricted directory. This could potentially lead to unauthorized read access to sensitive data or even system compromise.

Conceptual Example Code

Below is a conceptual HTTP request to illustrate how the vulnerability might be exploited. This request includes a malicious payload in the form of a crafted path that accesses a sensitive file outside the restricted directory.

GET /tabdocapi/duplicate-data-source?path=../../../../../../etc/passwd HTTP/1.1
Host: target.example.com

To mitigate this vulnerability, it is recommended to apply the vendor patch promptly. Alternatively, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and prevent path traversal attempts.
