CVE-2024-10946
📋 TL;DR
This is a SQL injection vulnerability in the Interlib Library Cluster Automation Management System that allows attackers to execute arbitrary SQL commands via the 'sql' parameter. It affects all versions up to 2.0.1 of the software. Attackers can exploit this remotely without authentication to potentially access or manipulate database contents.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, privilege escalation, and potential system takeover via SQL injection leading to remote code execution.
Likely Case
Unauthorized database access leading to sensitive information disclosure, data manipulation, and potential administrative access to the library management system.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
Exploit details have been publicly disclosed on multiple platforms including vuldb.com and shikangsi.com, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available - vendor did not respond to disclosure
Restart Required: No
Instructions:
No official patch available. Consider upgrading if vendor releases fixed version, or implement workarounds and mitigations.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the vulnerable endpoint
# Example ModSecurity rule for Apache:
SecRule REQUEST_URI "@streq /interlib/admin/SysLib" \
"chain,id:1001,phase:2,deny,status:403,msg:'SQLi attempt on Interlib endpoint'"
SecRule ARGS:sql "@detectSQLi"
Input Validation Filter
allAdd input validation to sanitize the 'sql' parameter before processing
# Example PHP input sanitization:
$sql_param = preg_replace('/[^a-zA-Z0-9\s_,]/', '', $_GET['sql']);
# Or better: use parameterized queries instead of string concatenation
🧯 If You Can't Patch
- Network segmentation: Isolate Interlib systems from internet and restrict access to authorized IPs only
- Database hardening: Implement least privilege database accounts, enable SQL injection protection features, and monitor for suspicious queries
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /interlib/admin/SysLib?cmdACT=inputLIBCODE&mod=batchXSL&xsl=editLIBCODE.xsl&libcodes=&ROWID=&sql=test' OR '1'='1Check Version:
Check software version in admin interface or configuration files; no standard command availableVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages or are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by SQL injection patterns
- Requests to /interlib/admin/SysLib with suspicious sql parameter values
Network Indicators:
- Unusual outbound database connections from web server
- SQL error messages in HTTP responses
- Patterns of SQL keywords in URL parameters
SIEM Query:
source="web_logs" AND uri="/interlib/admin/SysLib" AND (param="sql" AND value MATCH "(?i)(union|select|insert|update|delete|drop|exec|--|#|;)")
