The vulnerability identified as CVE-2008-0282 represents a critical SQL injection flaw within the DomPHP content management system version 0.81 and earlier. This vulnerability specifically affects the welcome/inscription.php script which handles user registration processes. The flaw arises from inadequate input validation and sanitization of the mail parameter, which is directly incorporated into SQL queries without proper escaping or parameterization mechanisms. The vulnerability is classified under CWE-89 which specifically addresses SQL injection weaknesses in software applications.
The technical exploitation of this vulnerability occurs when remote attackers submit maliciously crafted input through the mail parameter during the registration process. When the application processes this input, it fails to properly sanitize the data before incorporating it into database queries, allowing attackers to inject arbitrary SQL commands. This injection can manipulate the database operations to execute unauthorized queries, potentially leading to data extraction, modification, or deletion. The vulnerability is particularly dangerous because it operates at the database level and can be exploited without authentication, making it accessible to any remote attacker.
The operational impact of this vulnerability extends beyond simple data compromise. Attackers can leverage this weakness to gain unauthorized access to sensitive user information including email addresses, registration details, and potentially other database records. The vulnerability enables attackers to perform union-based attacks, boolean-based injections, or error-based exploitation techniques to extract database schema information and user credentials. Additionally, the attack can result in complete database compromise, allowing attackers to escalate privileges or modify the application's functionality. This vulnerability aligns with ATT&CK technique T1190 which describes exploitation of vulnerabilities in web applications to gain unauthorized access to systems.
Mitigation strategies for this vulnerability require immediate implementation of proper input validation and parameterized queries. The most effective approach involves replacing direct string concatenation of user input with prepared statements or parameterized queries that separate SQL command structure from data. Organizations should implement comprehensive input sanitization routines that validate email format and reject suspicious characters or sequences. The fix should include proper error handling to prevent information leakage and ensure that database connections use minimal privileges. Security patches should be applied immediately to upgrade to DomPHP versions that address this vulnerability, and application firewalls should be configured to monitor and filter suspicious SQL injection patterns. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components.
