The vulnerability identified as CVE-2005-1834 represents a critical SQL injection flaw within the login.asp component of NEXTWEB (i)Site web application. This security weakness resides in the authentication mechanism where user input is improperly sanitized before being incorporated into SQL database queries. The vulnerability specifically affects the password field processing, creating an avenue for malicious actors to manipulate the underlying database operations through crafted input sequences. The flaw enables attackers to construct malicious SQL statements that can be executed within the database context, potentially allowing full system compromise and unauthorized access to sensitive information.
From a technical perspective, the vulnerability manifests when the application fails to properly escape or parameterize user-supplied input before incorporating it into SQL query strings. When a user submits a password through the login.asp interface, the application directly concatenates this input into database queries without adequate input validation or sanitization measures. This primitive approach to data handling creates a direct injection vector where attackers can manipulate the intended query structure by embedding SQL syntax within the password field. The vulnerability aligns with CWE-89, which categorizes SQL injection as a common weakness in software applications where untrusted data is incorporated into SQL commands without proper sanitization. This particular flaw demonstrates a classic example of insecure direct object reference combined with improper input validation.
The operational impact of this vulnerability extends beyond simple authentication bypass to encompass potential data breach scenarios and system compromise. An attacker exploiting this vulnerability can execute arbitrary SQL commands against the underlying database, potentially gaining read access to user credentials, personal information, and other sensitive data stored within the application's database. The authentication bypass capability allows unauthorized users to assume legitimate user identities, leading to privilege escalation and further system infiltration. This vulnerability represents a significant threat to the confidentiality and integrity of the affected system, as it provides attackers with direct database access that could be leveraged for data exfiltration, manipulation, or destruction. The impact is particularly severe given that the vulnerability affects the core authentication mechanism, making it a prime target for exploitation.
Mitigation strategies for CVE-2005-1834 should prioritize immediate implementation of proper input validation and parameterized queries. Organizations must ensure that all user input, particularly in authentication fields, is rigorously validated and sanitized before being processed by the application. The recommended approach involves implementing prepared statements or parameterized queries that separate SQL command structure from data content, effectively neutralizing injection attack vectors. Additionally, input filtering should be applied to remove or escape potentially harmful characters that could be used in SQL injection attempts. Security measures should include regular code reviews focusing on database interaction patterns, implementation of web application firewalls to detect and block suspicious input patterns, and comprehensive testing including penetration testing to identify similar vulnerabilities. This vulnerability also highlights the importance of following secure coding practices and adhering to the principle of least privilege in database access control, ensuring that database users have minimal necessary permissions to reduce potential damage from successful attacks. The remediation process should align with ATT&CK technique T1190, which addresses exploitation of vulnerabilities in web applications, emphasizing the need for comprehensive vulnerability management and patching strategies to prevent such attacks from succeeding.
