What Salesforce’s Patch Nightmare Teaches About Tableau Server Risks
On June 26, 2025, Salesforce disclosed eight critical vulnerabilities in Tableau Server the widely deployed BI and analytics platform. These flaws, affecting versions prior to 2025.1.3, 2024.2.12, and 2023.3.19, open the door to remote code execution, unauthorized database access, SSRF, and path traversal attacks.
What Changed?
Salesforce issued an urgent advisory after uncovering:
A Remote Code Execution (RCE) flaw (CVE‑2025‑52449, CVSS 8.5) via unrestricted file upload with deceptive filenames. Three authorization bypass vulnerabilities (CVE‑2025‑52446, 52447, 52448; CVSS 8.0) that let attackers manipulate user-supplied API inputs and run arbitrary SQL commands on production databases. A path traversal issue (CVE‑2025‑52452, CVSS 8.5) enabling attackers to read sensitive files due to unvalidated pathname handling. Three Server-Side Request Forgery (SSRF) exploits (CVE‑2025‑52453, 52454, 52455; CVSS 8.1–8.2) across Flow Data Source, S3 Connector, and EPS modules — letting attackers make unauthorized requests to internal services.
What’s at Risk?
These vulnerabilities together create a potent attack chain:
- An attacker uploads a malicious file or crafts a special request.
- They gain RCE or read sensitive data via SQL or file traversal.
- SSRF enables pivoting into internal services or cloud infrastructure.
- Entire organization’s BI data and backend systems become exposed.
Immediate Action Plan: What You Should Do Now
If you’re running Tableau Server, time is of the essence. The vulnerabilities disclosed in recent days can allow attackers to exploit internal systems using techniques like SSRF and RCE. Here’s how to take control now:
✅ Upgrade to the Latest Maintenance Release
Ensure your Tableau Server is patched to the latest maintenance release available for your version. Don’t wait for scheduled updates this patch addresses critical security gaps that attackers can exploit remotely.
✅ Update Trino/Presto Drivers
If your Tableau Server integrates with Trino or Presto for SQL querying, immediately update those drivers. Older versions are vulnerable and could become potential entry points for lateral movement or data exfiltration.
Long-Term Defense Strategies
- Enforce strict upload validation and whitelisting
- Enable WAF or reverse proxy rules to detect SSRF/RCE patterns
- Implement Zero Trust controls around Tableau access
- Audit API logs for unauthorized SQL or file access
- Regularly scan sensitive endpoints and upgrade components promptly
At Finstein, we often say: Business intelligence platforms are only as safe as their weakest module. These Tableau vulnerabilities show how even internal analytics tools can expose critical data when attackers bypass application logic and exploit foundational flaws.
