The vulnerability identified as CVE-2011-5111 represents a critical SQL injection flaw within the Kajian Website CMS Balitbang version 3.x content management system. This vulnerability exposes the application to remote code execution risks through improper input validation mechanisms that fail to sanitize user-supplied data before incorporating it into database queries. The affected components include multiple modules within the CMS that process user requests without adequate parameter filtering, creating exploitable pathways for malicious actors to manipulate the underlying database infrastructure.
The technical implementation of this vulnerability stems from the application's failure to properly escape or validate the hal parameter in several key files including alumni.php and index.php. When users submit requests containing malicious SQL payloads through these parameters, the CMS directly incorporates the unsanitized input into SQL query constructions without appropriate sanitization measures. This design flaw aligns with CWE-89, which specifically addresses SQL injection vulnerabilities where user-controllable data is improperly integrated into database commands. The vulnerability affects five distinct modules within the CMS architecture, demonstrating a systemic weakness in input validation rather than isolated component failure.
The operational impact of this vulnerability extends beyond simple data theft or modification to encompass complete system compromise. Remote attackers can leverage these injection points to execute arbitrary SQL commands, potentially gaining unauthorized access to sensitive information, modifying or deleting database records, and establishing persistent access to the affected system. The attack surface is particularly concerning given that the vulnerability affects core modules such as lih_buku, artikel, album, and berita, which likely handle critical content management functions. This allows attackers to manipulate news articles, book listings, album content, and other published materials, potentially leading to information disclosure, data corruption, or complete system takeover.
Security professionals should recognize this vulnerability as a prime example of how insufficient input validation can create cascading security failures within web applications. The ATT&CK framework categorizes this type of vulnerability under T1071.004 for application layer protocol manipulation, where adversaries exploit weaknesses in application logic to gain unauthorized access to system resources. Mitigation strategies must include immediate implementation of proper parameterized queries, input validation, and output encoding mechanisms to prevent malicious SQL code from being executed. Additionally, regular security assessments and code reviews should be conducted to identify similar vulnerabilities within the application's codebase, ensuring that all user-supplied inputs are properly sanitized before being processed by database systems.
