CVE-2009-0447 in MyDesign Sayac
Summary
by MITRE
Multiple SQL injection vulnerabilities in default.asp in MyDesign Sayac 2.0 allow remote attackers to execute arbitrary SQL commands via (1) the user parameter (aka UserName field) or (2) the pass parameter (aka Pass field) to (a) admin/admin.asp or (b) the default URI under admin/. NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2009-0447 represents a critical SQL injection flaw in MyDesign Sayac 2.0 web application, specifically affecting the default.asp file. This vulnerability exposes the application to remote code execution attacks through improper input validation mechanisms. The flaw manifests when user-supplied data is directly concatenated into SQL query strings without adequate sanitization or parameterization, creating a pathway for malicious actors to manipulate database queries. The vulnerability affects two distinct input parameters: the user parameter (UserName field) and the pass parameter (Pass field), which are processed in both admin/admin.asp and the default URI under the admin/ directory. These attack vectors demonstrate a fundamental weakness in the application's authentication mechanism where credentials are handled through insecure database query construction.
The technical exploitation of this vulnerability aligns with CWE-89, which categorizes SQL injection as a severe weakness in software design. Attackers can leverage this flaw by crafting malicious input strings that alter the intended flow of SQL commands, potentially allowing them to extract sensitive data, modify database contents, or even gain administrative privileges within the application. The vulnerability's impact extends beyond simple data theft as it can enable complete system compromise through database manipulation and privilege escalation techniques. The fact that both authentication parameters are vulnerable indicates a systemic issue in how the application handles user input, suggesting that the developers failed to implement proper input validation and sanitization measures across critical authentication pathways.
From an operational perspective, this vulnerability creates significant risk for organizations utilizing MyDesign Sayac 2.0, as it provides attackers with direct access to the underlying database infrastructure. The attack surface is particularly concerning given that the vulnerability affects both the username and password fields in the administrative interface, meaning that successful exploitation could lead to full administrative control over the application. This type of vulnerability often maps to ATT&CK technique T1190, which describes the use of vulnerabilities in software applications to gain unauthorized access. The remote nature of the attack means that exploitation can occur from any location with internet access, making it particularly dangerous for web applications that are exposed to public networks. Organizations may face regulatory compliance issues and potential data breaches if this vulnerability is exploited, as it could lead to unauthorized access to sensitive user information and system resources.
Mitigation strategies for CVE-2009-0447 should focus on implementing proper input validation and parameterized queries to prevent SQL injection attacks. The most effective approach involves replacing direct string concatenation with prepared statements or parameterized queries that separate SQL command structure from user input. Organizations should also implement proper authentication mechanisms with secure password handling, including password hashing and salting techniques. Additionally, regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other application components. Network segmentation and access controls can help limit the potential impact if exploitation occurs, while monitoring and logging should be enhanced to detect suspicious authentication attempts. The vulnerability also highlights the importance of keeping web applications updated with the latest security patches and following secure coding practices that prevent common injection flaws. Organizations should consider implementing web application firewalls as an additional layer of protection against SQL injection attacks and other common web vulnerabilities.
