CVE-2006-0403 in e-moBLOG
Summary
by MITRE
Multiple SQL injection vulnerabilities in e-moBLOG 1.3 allow remote attackers to execute arbitrary SQL commands via the (1) monthy parameter to index.php or (2) login parameter to admin/index.php. NOTE: some sources have reported item 1 as involving the "monthly" parameter, but this is incorrect.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability described in CVE-2006-0403 represents a critical SQL injection flaw affecting e-moBLOG version 1.3, a web-based content management system. This vulnerability exists within the application's input validation mechanisms, specifically targeting two distinct parameters that handle user-supplied data without proper sanitization. The flaw allows remote attackers to manipulate the database queries executed by the application through maliciously crafted input, potentially leading to unauthorized data access, modification, or complete system compromise.
The technical implementation of this vulnerability stems from the application's failure to properly escape or validate user input before incorporating it into SQL query strings. When the monthy parameter in index.php or the login parameter in admin/index.php receives untrusted data, the application directly concatenates this input into database queries without appropriate sanitization measures. This creates an environment where attackers can inject malicious SQL code that gets executed by the database engine, effectively bypassing the application's authentication and authorization controls.
From an operational perspective, this vulnerability poses significant risks to system integrity and data confidentiality. Attackers exploiting this flaw can execute arbitrary SQL commands, potentially gaining access to sensitive user credentials, personal information, and other database contents. The impact extends beyond simple data theft, as successful exploitation could enable attackers to modify or delete database records, escalate privileges within the application, or even use the compromised system as a launching point for further attacks within the network infrastructure. The remote nature of this vulnerability means attackers do not require physical access to the system and can exploit it from anywhere on the internet.
The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws in software applications. This classification indicates that the flaw represents a well-documented and widely recognized security weakness that has been extensively studied in the cybersecurity community. From an ATT&CK framework perspective, this vulnerability maps to techniques involving command and control communications, credential access, and privilege escalation. The attack surface is particularly concerning given that it affects both frontend and backend administrative interfaces, providing attackers with multiple potential entry points for exploitation.
Mitigation strategies should include immediate implementation of proper input validation and parameterized queries to prevent SQL injection attacks. Developers must ensure that all user-supplied input is properly sanitized before being incorporated into database queries, utilizing prepared statements or parameterized queries that separate the SQL command structure from the data being processed. Additionally, implementing proper access controls, regular security audits, and keeping the application updated with security patches are essential defensive measures. Organizations should also consider network segmentation and monitoring solutions to detect and respond to potential exploitation attempts. The vulnerability highlights the critical importance of secure coding practices and demonstrates how seemingly simple input handling flaws can create significant security risks in web applications.
