CVE-2025-70982

9.9 CRITICAL

📋 TL;DR

CVE-2025-70982 is an improper access control vulnerability in SpringBlade v4.5.0 that allows attackers with low-level privileges to import sensitive user data without proper authorization. This affects any organization using the vulnerable version of SpringBlade, potentially exposing user information to unauthorized actors.

💻 Affected Systems

Products:
  • SpringBlade
Versions: v4.5.0
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the importUser function specifically. Any deployment using SpringBlade v4.5.0 with user import functionality enabled is affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could import and exfiltrate all user data including credentials, personal information, and system accounts, leading to complete data breach and potential account takeover.

🟠

Likely Case

Low-privileged users or attackers who gain initial access could escalate privileges by importing administrative accounts or access sensitive user information.

🟢

If Mitigated

With proper access controls and authentication mechanisms, the impact would be limited to authorized users only performing legitimate import operations.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires low-level privileges. The GitHub issue and gist provide technical details that could be used to develop exploits.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v4.5.1 or later

Vendor Advisory: https://github.com/chillzhuang/SpringBlade/issues/34

Restart Required: Yes

Instructions:

1. Backup current configuration and data. 2. Update SpringBlade to version 4.5.1 or later. 3. Restart the application server. 4. Verify the fix by testing user import functionality with low-privilege accounts.

🔧 Temporary Workarounds

Disable User Import Function

all

Temporarily disable the importUser functionality until patching can be completed.

Modify application configuration to remove or disable importUser endpoint access

Implement Additional Access Controls

all

Add role-based access control checks before the importUser function executes.

Implement @PreAuthorize("hasRole('ADMIN')") annotation on importUser method

🧯 If You Can't Patch

  • Implement network segmentation to isolate SpringBlade instances from sensitive data stores
  • Enable detailed audit logging for all user import operations and monitor for unauthorized attempts

🔍 How to Verify

Check if Vulnerable:

Check if running SpringBlade v4.5.0 and test if low-privilege users can access the importUser functionality.

Check Version:

Check application.properties or pom.xml for SpringBlade version, or use: java -jar your-application.jar --version

Verify Fix Applied:

After updating to v4.5.1+, verify that low-privilege users cannot access importUser functionality and only authorized roles can perform imports.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized access attempts to importUser endpoint
  • User import operations from non-admin accounts
  • Multiple failed authentication attempts followed by successful import

Network Indicators:

  • HTTP POST requests to /api/user/import from unexpected IP addresses
  • Unusual data export patterns following user imports

SIEM Query:

source="springblade.logs" AND (uri_path="/api/user/import" AND user_role!="ADMIN")
