CVE-2024-25509
📋 TL;DR
This SQL injection vulnerability in RuvarOA allows attackers to execute arbitrary SQL commands via the sys_file_storage_id parameter in the wf_file_download.aspx endpoint. Successful exploitation could lead to data theft, authentication bypass, or complete system compromise. Organizations using RuvarOA v6.01 or v12.01 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation to administrative access, and potential remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive workflow files and database information, potentially including user credentials and confidential business documents.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification privileges.
🎯 Exploit Status
Public proof-of-concept demonstrates the injection technique. The vulnerability requires no authentication and uses simple SQL injection payloads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available from the vendor, or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
windowsImplement server-side input validation to sanitize the sys_file_storage_id parameter, allowing only expected data types.
Implement parameterized queries or stored procedures in the wf_file_download.aspx code
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint.
Add WAF rule: Block requests to /WorkFlow/wf_file_download.aspx containing SQL keywords in parameters
🧯 If You Can't Patch
- Implement network segmentation to restrict access to RuvarOA servers only to authorized users and systems.
- Deploy database monitoring to detect unusual SQL queries and implement principle of least privilege for database accounts.
🔍 How to Verify
Check if Vulnerable:
Test the /WorkFlow/wf_file_download.aspx endpoint with SQL injection payloads in the sys_file_storage_id parameter and observe database errors or unexpected responses.Check Version:
Check RuvarOA version through the application interface or configuration files (typically in installation directory).Verify Fix Applied:
After implementing fixes, retest with SQL injection payloads to confirm they are properly blocked or sanitized without causing database errors.📡 Detection & Monitoring
Log Indicators:
- Unusual database query patterns from the RuvarOA application
- Multiple failed requests to wf_file_download.aspx with SQL keywords in parameters
- Database error messages in application logs
Network Indicators:
- HTTP requests to /WorkFlow/wf_file_download.aspx containing SQL injection patterns like UNION, SELECT, OR 1=1
SIEM Query:
source="web_server" AND uri="/WorkFlow/wf_file_download.aspx" AND (param="sys_file_storage_id" AND value MATCHES "(?i)(union|select|or\s+1=1|--|;)")
