CVE-2019-25643 Overview
eNdonesia Portal v8.7 contains multiple SQL injection vulnerabilities that allow unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the bid parameter. Attackers can send GET requests to banners.php with crafted SQL payloads in the bid parameter to extract sensitive database information from the INFORMATION_SCHEMA tables.
Critical Impact
Unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive database contents, potentially compromising user credentials, application data, and underlying system information without requiring any authentication.

Technical Details for CVE-2019-25643
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) exists in the banners.php file of eNdonesia Portal v8.7. The application fails to properly sanitize user-supplied input in the bid parameter before incorporating it into SQL queries. This allows attackers to manipulate the database query structure by injecting malicious SQL code directly through the URL parameter.
The vulnerability is accessible over the network without authentication, making it particularly dangerous for internet-facing installations. Successful exploitation enables attackers to query the INFORMATION_SCHEMA tables, enumerate database structure, and extract sensitive data from all accessible tables within the database.
Root Cause
The root cause of this vulnerability is improper input validation and lack of parameterized queries in the banners.php script. User-supplied data from the bid GET parameter is directly concatenated into SQL statements without sanitization, escaping, or the use of prepared statements. This classic SQL injection pattern allows attackers to break out of the intended query context and inject arbitrary SQL commands.
Attack Vector
The attack is executed remotely over the network by crafting malicious HTTP GET requests to the vulnerable banners.php endpoint. An attacker constructs a URL with a specially crafted bid parameter containing SQL injection payloads. The malicious SQL code is then processed by the backend database, allowing the attacker to extract data from INFORMATION_SCHEMA tables and potentially access all database contents.
The exploitation requires no authentication or user interaction, making it trivially exploitable by anyone who can reach the target web server. Public exploit code is available through Exploit-DB #46559, which provides proof-of-concept payloads for this vulnerability.
Detection Methods for CVE-2019-25643
Indicators of Compromise
- HTTP GET requests to banners.php containing SQL keywords such as UNION, SELECT, INFORMATION_SCHEMA, or comment sequences like -- in the bid parameter
- Database query logs showing unusual queries targeting system tables or metadata schemas
- Unexpected database enumeration activities or bulk data extraction patterns in application logs
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block SQL injection patterns in the bid parameter
- Monitor web server access logs for requests to banners.php with abnormally long or encoded bid parameter values
- Deploy intrusion detection system (IDS) signatures targeting common SQL injection payloads
Monitoring Recommendations
- Enable detailed database query logging and alert on queries accessing INFORMATION_SCHEMA tables from the web application
- Configure real-time alerting for multiple failed or anomalous requests targeting banners.php
- Review web access logs periodically for reconnaissance activity targeting banner-related endpoints
How to Mitigate CVE-2019-25643
Immediate Actions Required
- Consider taking the eNdonesia Portal offline or restricting access until a fix is applied
- Implement web application firewall rules to block SQL injection attempts targeting the bid parameter
- Review database accounts used by the application and restrict permissions to minimum required privileges
Patch Information
No official vendor patch information is available at this time. The eNdonesia project appears to be an older content management system with limited active development. Administrators should consult the eNdonesia SourceForge Project for any available updates or community patches. Additional technical details about the vulnerability are available through the VulnCheck SQL Injection Advisory.
Workarounds
- Deploy a web application firewall (WAF) in front of the application with rules to filter SQL injection patterns from the bid parameter
- Modify the banners.php source code to use parameterized queries or prepared statements for all database operations
- Restrict network access to the eNdonesia Portal to trusted IP ranges only
- Consider migrating to a modern, actively maintained content management system with better security practices
# Example WAF rule to block SQL injection in bid parameter (ModSecurity syntax)
SecRule ARGS:bid "@rx (?i)(union|select|insert|update|delete|drop|information_schema|--)" \
"id:1001,phase:2,deny,status:403,msg:'SQL Injection attempt blocked in bid parameter'"
