The CVE-2004-1552 vulnerability represents a critical sql injection flaw in the aspWebCalendar application that exposes remote attackers to potential system compromise. This vulnerability resides within the authentication and event management components of the web calendar system, creating multiple attack vectors that can be exploited without requiring prior authentication. The flaw specifically affects the handling of user input in two distinct locations, making it particularly dangerous as it provides attackers with multiple pathways to execute malicious sql commands against the underlying database. The vulnerability stems from insufficient input validation and improper parameter sanitization within the application's backend sql queries.
The technical implementation of this vulnerability occurs when user-supplied data enters the application through the username field during login attempts or through the eventid parameter in calendar.asp requests. In both cases, the application directly incorporates user input into sql query construction without proper sanitization or parameterization. When an attacker submits malicious sql payload through either input field, the application processes these inputs without adequate validation, allowing the injected sql commands to execute within the database context. This improper handling of user input violates fundamental secure coding principles and creates a direct pathway for attackers to manipulate database operations.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation can lead to complete database compromise, unauthorized access to calendar events, user credentials, and potentially broader system infiltration. Attackers can leverage this vulnerability to extract sensitive information, modify calendar entries, delete events, or even escalate privileges within the database environment. The vulnerability's remote nature means that attackers can exploit it from anywhere on the internet without requiring physical access to the system. This makes it particularly attractive to automated attack tools and increases the potential for widespread exploitation across multiple installations of the vulnerable software.
Organizations affected by this vulnerability should implement immediate mitigations including input validation and parameterized queries to prevent sql injection attacks. The recommended approach involves sanitizing all user inputs through proper encoding and validation before processing, implementing prepared statements or parameterized queries, and employing web application firewalls to detect and block malicious sql payloads. Additionally, security teams should conduct comprehensive code reviews to identify similar vulnerabilities in other application components and establish proper database access controls to limit the impact of potential breaches. This vulnerability aligns with CWE-89 sql injection weakness and follows attack patterns documented in the attack tree framework, particularly targeting the credential compromise and data manipulation phases of the kill chain. The vulnerability demonstrates the critical importance of input validation and proper sql query construction in preventing remote code execution through database interfaces.
