CVE-2025-3707
📋 TL;DR
The eHDR CTMS from Sunnet contains a SQL injection vulnerability that allows authenticated users with regular privileges to execute arbitrary SQL commands and read database contents. This affects organizations using the vulnerable eHDR CTMS software for clinical trial management.
💻 Affected Systems
- Sunnet eHDR CTMS
📦 What is this software?
Ehrd Ctms by Sun.net
⚠️ Risk & Real-World Impact
Worst Case
Attackers could extract sensitive clinical trial data, patient information, and administrative credentials, potentially leading to data breach, regulatory violations, and system compromise.
Likely Case
Attackers with regular user access could read database tables containing clinical trial data, user information, and system configuration details.
If Mitigated
With proper input validation and parameterized queries, SQL injection would be prevented, limiting database access to authorized queries only.
🎯 Exploit Status
Requires authenticated access but SQL injection is typically straightforward to exploit with basic tools
