CVE-2008-7049 in NatterChat
Summary
by MITRE
Multiple SQL injection vulnerabilities in login.asp in NatterChat 1.1 and 1.12 allow remote attackers to execute arbitrary SQL commands via the (1) txtUsername parameter (aka Username) and (2) txtPassword parameter (aka Password) in a form generated by home.asp. NOTE: due to lack of details, it is not clear whether this is related to CVE-2004-2206.

The vulnerability identified as CVE-2008-7049 represents a critical SQL injection flaw in NatterChat versions 1.1 and 1.12, specifically affecting the login.asp component. This vulnerability resides within the authentication mechanism of the web application, where user input is improperly sanitized before being incorporated into SQL queries. The flaw manifests through two primary attack vectors corresponding to the txtUsername and txtPassword parameters, which are processed in the login form generated by home.asp. These parameters serve as direct entry points for malicious actors to inject arbitrary SQL commands into the backend database system.
The technical exploitation of this vulnerability occurs when an attacker submits specially crafted input through the username and password fields of the login form. The application fails to implement proper input validation or parameterized queries, allowing the malicious SQL code to be executed within the database context. This weakness directly maps to CWE-89, which categorizes SQL injection vulnerabilities as a fundamental flaw in input handling and query construction. The vulnerability enables attackers to bypass authentication mechanisms, potentially gaining unauthorized access to user accounts and sensitive database information. Attackers could leverage this flaw to extract user credentials, modify database records, or even escalate privileges within the application's database environment.
The operational impact of CVE-2008-7049 extends beyond simple unauthorized access, as it represents a severe compromise of the application's integrity and confidentiality. Successful exploitation could result in complete database compromise, allowing attackers to view, modify, or delete sensitive user information including hashed passwords, personal details, and potentially system configuration data. The vulnerability affects the core authentication functionality, undermining the trust model of the web application and creating persistent access vectors for malicious actors. Organizations relying on NatterChat versions 1.1 and 1.12 face significant risk of data breaches, unauthorized system access, and potential lateral movement within their network infrastructure. This vulnerability aligns with ATT&CK technique T1190, which describes the exploitation of vulnerabilities in web applications to gain unauthorized access.
Mitigation strategies for this vulnerability require immediate implementation of input sanitization and parameterized query mechanisms. The most effective remediation involves converting all dynamic SQL queries to use parameterized or prepared statements, ensuring that user input is properly escaped or validated before database processing. Additionally, implementing proper input validation, output encoding, and least privilege database access controls can significantly reduce the attack surface. Security patches should be applied immediately to update the NatterChat software to versions that address these SQL injection vulnerabilities. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for exploitation attempts. The vulnerability demonstrates the critical importance of secure coding practices and proper input handling, as outlined in OWASP Top Ten and other industry security frameworks, which emphasize the necessity of protecting against injection flaws as one of the most prevalent and dangerous web application security risks.
