CVE-2005-4225 in myBloggie
Summary
by MITRE
Multiple "potential" SQL injection vulnerabilities in myBloggie 2.1.3 beta might allow remote attackers to execute arbitrary SQL commands via (1) the category parameter in add.php, (2) the cat_desc parameter in addcat.php, (3) the level and user parameters in adduser.php, (4) the post_id parameter in del.php, (5) the cat_id parameter in delcat.php, (6) the comment_id parameter in delcomment.php, (7) the id parameter in deluser.php, (8) the post_id and category parameter in edit.php, (9) the cat_id and cat_desc parameters in editcat.php, and (10) the id, level, and user parameters in edituser.php. NOTE: the username/login.php vector is already identified by CVE-2005-2838.

The vulnerability described in CVE-2005-4225 represents a critical SQL injection flaw affecting myBloggie 2.1.3 beta content management system. This vulnerability manifests across multiple script files within the application, creating numerous attack vectors that could potentially allow remote attackers to execute arbitrary SQL commands on the underlying database server. The flaw stems from insufficient input validation and sanitization of user-supplied parameters, which are directly incorporated into SQL query constructions without proper escaping or parameterization techniques. The vulnerability affects core administrative and content management functions, making it particularly dangerous as it could enable attackers to manipulate the entire database structure and potentially gain unauthorized access to sensitive information.
The technical implementation of this vulnerability follows the classic SQL injection pattern where user-controllable parameters are concatenated directly into SQL statements without adequate sanitization. Attackers can exploit this by crafting malicious input values that alter the intended SQL query structure, potentially leading to data extraction, modification, or deletion. The vulnerability spans across multiple endpoints including add.php, addcat.php, adduser.php, del.php, delcat.php, delcomment.php, deluser.php, edit.php, editcat.php, and edituser.php, each representing different attack surfaces within the application's administrative interface. These parameters include category, cat_desc, level, user, post_id, cat_id, comment_id, id, and others that are commonly used for database operations. The presence of multiple vulnerable parameters increases the attack surface significantly and provides attackers with various pathways to achieve their objectives.
The operational impact of this vulnerability extends beyond simple data manipulation to potentially compromise the entire application infrastructure. Remote attackers could leverage these vulnerabilities to extract sensitive user credentials, modify blog content, delete database entries, or even escalate privileges within the system. The vulnerability's classification aligns with CWE-89 which specifically addresses SQL injection flaws, and it demonstrates characteristics consistent with ATT&CK technique T1071.004 for application layer protocol manipulation. Given that these vulnerabilities affect core administrative functions, successful exploitation could result in complete system compromise, data breaches, and unauthorized content modification. The fact that CVE-2005-2838 already covers the username/login.php vector indicates this was part of a broader attack surface that required comprehensive remediation across all affected components.
Mitigation strategies should focus on implementing proper input validation, parameterized queries, and output encoding throughout all affected scripts. The recommended approach involves using prepared statements or stored procedures that separate SQL code from data, ensuring that user input cannot alter the intended query structure. Additionally, implementing proper access controls, input sanitization routines, and regular security audits would significantly reduce the risk of exploitation. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for suspicious SQL query patterns. The vulnerability highlights the critical importance of secure coding practices and proper database access controls in web applications, particularly those handling user-generated content and administrative functions. Regular security assessments and timely patch management remain essential for protecting against similar vulnerabilities in modern applications.
