CVE-2007-4956 in KwsPHP
Summary
by MITRE
Multiple SQL injection vulnerabilities in KwsPHP 1.0 allow remote attackers to execute arbitrary SQL commands via (1) the pseudo parameter to login.php, (2) the id parameter to index.php in a carnet editer action in the Member_Space (espace_membre) module, or (3) the typenav parameter to index.php in a browser aff action in the stats module.

The vulnerability described in CVE-2007-4956 represents a critical SQL injection flaw affecting KwsPHP version 1.0, specifically targeting the Member_Space and stats modules. This vulnerability enables remote attackers to execute arbitrary SQL commands by manipulating specific parameters within the application's web interface. The affected parameters include the pseudo parameter in login.php, the id parameter in index.php during carnet editer actions, and the typenav parameter in index.php during browser aff actions. These injection points occur within the application's authentication and statistical reporting modules, creating multiple attack vectors for malicious actors seeking to compromise the system's database integrity.
The technical exploitation of these vulnerabilities stems from improper input validation and sanitization within the KwsPHP application's codebase. When user-supplied input is directly concatenated into SQL queries without adequate escaping or parameterization, attackers can inject malicious SQL code that executes with the privileges of the database user. The pseudo parameter in login.php suggests that authentication mechanisms lack proper input sanitization, while the id parameter in carnet editer actions indicates that member data editing functions are vulnerable to SQL injection attacks. The typenav parameter in the stats module reveals that statistical reporting features also suffer from inadequate input validation, potentially allowing attackers to manipulate database queries for data extraction or modification.
The operational impact of these vulnerabilities extends beyond simple data theft, as they provide attackers with the capability to perform complete database compromise. Successful exploitation could enable attackers to extract sensitive user information, modify member records, manipulate statistical data, or even gain unauthorized access to the underlying database system. The presence of multiple attack vectors increases the likelihood of successful exploitation and provides attackers with alternative pathways if one vector is detected or blocked. These vulnerabilities particularly affect web applications following the common OWASP Top Ten security risks, specifically targeting injection flaws categorized under CWE-89, which represents the most prevalent and dangerous form of injection attacks in web applications.
The exploitation of these SQL injection vulnerabilities aligns with several tactics outlined in the MITRE ATT&CK framework, particularly focusing on credential access and data manipulation techniques. Attackers leveraging these flaws would likely employ techniques such as SQL injection to extract database credentials, manipulate user accounts, or access restricted information. The attack surface encompasses both authentication and reporting modules, indicating that defenders must implement comprehensive input validation across all user-facing application parameters. Organizations using KwsPHP 1.0 should prioritize immediate patching and implementation of proper parameterized queries to prevent exploitation. The vulnerability demonstrates the critical importance of input validation and the principle of least privilege in database access control, as recommended by industry standards including NIST SP 800-163 and ISO/IEC 27001 security frameworks. Additionally, implementing web application firewalls and regular security assessments can help detect and prevent exploitation attempts targeting these specific injection points in the Member_Space and stats modules.
