CVE-2025-50240

9.8 CRITICAL

📋 TL;DR

CVE-2025-50240 is a critical SQL injection vulnerability in nbcio-boot v1.0.3 that allows attackers to execute arbitrary SQL commands via the userIds parameter in the deleteRecycleBin endpoint. This affects all systems running the vulnerable version of nbcio-boot, potentially compromising database integrity and confidentiality.

💻 Affected Systems

Products:
  • nbcio-boot
Versions: v1.0.3
Operating Systems: All platforms running nbcio-boot
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the /sys/user/deleteRecycleBin endpoint specifically; other endpoints may also be vulnerable if similar code patterns exist.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including data exfiltration, modification, or deletion; potential remote code execution if database configuration permits.

🟠

Likely Case

Unauthorized data access, privilege escalation, or data manipulation affecting user accounts and system data.

🟢

If Mitigated

Limited impact with proper input validation and parameterized queries in place.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Exploitation requires access to the vulnerable endpoint; SQL injection via userIds parameter is straightforward with common tools like sqlmap.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://gitee.com/nbacheng/nbcio-boot/

Restart Required: No

Instructions:

Check the nbcio-boot repository for updates; apply any security patches; implement parameterized queries for the userIds parameter.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation for the userIds parameter to allow only expected formats (e.g., numeric IDs).

Web Application Firewall (WAF) Rules

all

Deploy WAF rules to block SQL injection patterns targeting the /sys/user/deleteRecycleBin endpoint.

🧯 If You Can't Patch

  • Disable or restrict access to the /sys/user/deleteRecycleBin endpoint via network controls or authentication.
  • Monitor logs for unusual SQL queries or access patterns to the vulnerable endpoint.

🔍 How to Verify

Check if Vulnerable:

Test the /sys/user/deleteRecycleBin endpoint with SQL injection payloads in the userIds parameter (e.g., using tools like sqlmap).

Check Version:

Check the nbcio-boot version in configuration files or via application metadata.

Verify Fix Applied:

Verify that parameterized queries are implemented and input validation rejects malicious payloads.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in application logs
  • Multiple failed login attempts or parameter tampering

Network Indicators:

  • HTTP requests to /sys/user/deleteRecycleBin with suspicious userIds values

SIEM Query:

source="web_logs" AND uri="/sys/user/deleteRecycleBin" AND (userIds CONTAINS "'" OR userIds CONTAINS "--" OR userIds CONTAINS ";")
