CVE-2019-25643 in eNdonesia Portal
Summary
by MITRE • 03/24/2026
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.

The vulnerability identified as CVE-2019-25643 affects eNdonesia Portal version 8.7 and represents a critical SQL injection flaw that undermines the application's database security. This vulnerability resides within the banners.php script where the bid parameter is processed without adequate input validation or sanitization, creating an exploitable entry point for malicious actors. The flaw allows unauthenticated attackers to inject arbitrary SQL commands directly into the database query execution flow, bypassing normal authentication mechanisms and potentially gaining unauthorized access to sensitive information stored within the system's database infrastructure.
The technical exploitation of this vulnerability follows a well-established pattern of SQL injection attacks where attackers manipulate the bid parameter through GET requests to the banners.php endpoint. When the application processes these requests, it concatenates the malicious SQL payload directly into the database query without proper parameterization or escaping mechanisms. This allows threat actors to construct queries that can extract data from INFORMATION_SCHEMA tables, which contain metadata about the database structure including table names, column definitions, and user credentials. The vulnerability specifically leverages the application's failure to implement proper input sanitization techniques, enabling attackers to manipulate the SQL execution context and gain access to information that should remain protected.
From an operational impact perspective, this vulnerability presents significant risks to organizations using the eNdonesia Portal system, particularly those handling sensitive data or user information. The ability to extract database schema information through INFORMATION_SCHEMA tables provides attackers with detailed knowledge of the database structure, which can be used to plan more sophisticated attacks targeting specific data elements. The unauthenticated nature of this exploit means that any external attacker with knowledge of the application's URL structure can potentially access sensitive information without requiring valid credentials or prior access privileges. This vulnerability essentially provides a backdoor for data exfiltration and can lead to complete database compromise when combined with other exploitation techniques.
The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws in software applications, and follows patterns commonly referenced in the MITRE ATT&CK framework under the technique T1071.004 for application layer protocol manipulation. Organizations affected by this vulnerability should implement immediate mitigations including input validation for all parameters, parameterized queries, and proper database access controls. The recommended defense-in-depth strategies include implementing web application firewalls, conducting regular security assessments, and ensuring proper database privilege management to limit the impact of potential exploitation. Additionally, the vulnerability demonstrates the critical importance of secure coding practices and input validation in preventing common injection attacks that continue to plague web applications across various platforms and technologies.
