CVE-2007-1899 in myBloggie
Summary
by MITRE
Multiple SQL injection vulnerabilities in myWebland myBloggie 2.1.6 allow remote attackers to execute arbitrary SQL commands via (1) the user_id parameter in a viewuser action to index.php, and allow remote authenticated administrators to execute arbitrary SQL commands via (2) the post_id parameter in an edit action to admin.php.

The vulnerability described in CVE-2007-1899 represents a critical SQL injection flaw within the myWebland myBloggie 2.1.6 content management system that exposes the application to remote code execution attacks. This vulnerability manifests through two distinct attack vectors that exploit improper input validation mechanisms within the web application's database interaction layers. The first vector targets the user_id parameter in the viewuser action of the index.php file, while the second vector targets the post_id parameter in the edit action of the admin.php file, creating separate pathways for exploitation based on the attacker's authentication status.
The technical exploitation of this vulnerability occurs when user-supplied input is directly concatenated into SQL query strings without proper sanitization or parameterization. In the case of the viewuser action, when an attacker submits a malicious user_id parameter, the application fails to validate or escape special characters that could alter the intended SQL command structure. Similarly, in the admin.php edit action, the post_id parameter lacks adequate input filtering, allowing authenticated administrators with malicious intent to manipulate database queries. This flaw directly maps to CWE-89 which categorizes SQL injection vulnerabilities as weaknesses in software that allows attackers to manipulate database queries through improper input handling. The vulnerability demonstrates a classic lack of input validation and output encoding practices that are fundamental to preventing injection attacks.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with the capability to execute arbitrary SQL commands on the underlying database server. Remote attackers can leverage the first vector to perform unauthorized database operations including data retrieval, modification, or deletion without authentication, potentially leading to complete database compromise. The second vector, while requiring authentication, allows authenticated administrators to escalate their privileges or perform unauthorized actions within the application's administrative interface. This vulnerability creates a pathway for attackers to access sensitive user data, modify content, and potentially establish persistent access to the system. According to ATT&CK framework, this vulnerability corresponds to T1071.004 for application layer protocol manipulation and T1190 for exploitation of remote services, representing both network-level and application-level attack vectors that could lead to full system compromise.
Mitigation strategies for this vulnerability must address both the immediate code-level fixes and broader security practices within the application architecture. The primary solution involves implementing proper parameterized queries or prepared statements that separate SQL command structure from user input data, ensuring that all user-supplied parameters are properly escaped or validated before database interaction. Input validation should be implemented at multiple levels including client-side and server-side to prevent malicious data from reaching the database layer. Additionally, the application should enforce the principle of least privilege by limiting database user permissions to only those operations necessary for normal application function. Security measures should include regular code reviews focusing on database interaction patterns, implementation of web application firewalls to detect suspicious SQL patterns, and comprehensive testing including automated vulnerability scanning and manual penetration testing. The vulnerability also highlights the importance of keeping software updated and following secure coding practices that align with industry standards such as those outlined in the OWASP Top Ten and NIST cybersecurity guidelines.
