📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, destruction, or ransomware deployment, potentially resulting in full system takeover.
Likely Case
Unauthorized data access and manipulation, including extraction of sensitive information like user credentials, financial data, or personal records.
If Mitigated
Limited impact with proper input validation, parameterized queries, and web application firewall rules blocking malicious SQL patterns.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited with readily available tools, making this highly accessible to attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific version
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-dm-corporative-cms-dmacroweb
Restart Required: Yes
Instructions:
1. Review the vendor advisory. 2. Download and apply the latest patch from the official vendor source. 3. Restart the CMS service. 4. Verify the fix by testing the vulnerable endpoint.
🔧 Temporary Workarounds
Web Application Firewall Rule
allImplement WAF rules to block SQL injection patterns targeting /antbuspre.asp parameters
# Example ModSecurity rule: SecRule ARGS:name "@detectSQLi" "id:1001,phase:2,deny,status:403"
Input Validation Filter
allAdd server-side validation to sanitize name and cod parameters
# Example PHP filter: $name = preg_replace('/[^a-zA-Z0-9]/', '', $_GET['name']);
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries in the application code
- Deploy a web application firewall with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Test the /antbuspre.asp endpoint with SQL injection payloads in name and cod parameters (e.g., name=test' OR '1'='1)Check Version:
Check CMS version in admin panel or configuration filesVerify Fix Applied:
Retest with SQL injection payloads after patching; successful requests should return error messages or be blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts or parameter manipulation in access logs
Network Indicators:
- HTTP requests to /antbuspre.asp with SQL keywords in parameters
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND uri="/antbuspre.asp" AND (param="name" OR param="cod") AND (query="UNION" OR query="SELECT" OR query="INSERT" OR query="DELETE")
