The vulnerability identified as CVE-2005-2404 represents a critical SQL injection flaw within the sendcard.php script of Sendcard version 3.2.3. This vulnerability resides in the handling of user input parameters, specifically the 'id' parameter that is processed without adequate sanitization or validation. The flaw allows remote attackers to inject malicious SQL commands directly into the application's database query execution flow, potentially compromising the entire database infrastructure. The vulnerability stems from the application's failure to properly escape or parameterize user-supplied input before incorporating it into SQL statements, creating an avenue for unauthorized database access and manipulation.
From a technical perspective, the vulnerability operates through the exploitation of improper input validation mechanisms within the sendcard.php script. When the 'id' parameter is submitted by an attacker, the application directly incorporates this value into a SQL query without any form of input sanitization or parameter binding. This design flaw aligns with CWE-89, which specifically addresses SQL injection vulnerabilities where untrusted data is directly included in SQL commands. The attack vector is particularly dangerous as it requires no authentication or privileged access, making it a remote code execution vulnerability that can be exploited from any network location. The vulnerability demonstrates a classic lack of proper input filtering and output encoding practices that are fundamental to preventing injection attacks.
The operational impact of this vulnerability extends beyond simple data theft, encompassing complete database compromise and potential system-wide exploitation. An attacker could leverage this vulnerability to extract sensitive information including user credentials, personal data, and system configuration details stored within the database. Additionally, the attacker might be able to modify or delete database records, insert malicious entries, or even escalate privileges within the database environment. The vulnerability creates a persistent threat that can be exploited repeatedly, as the underlying code flaw remains unaddressed. This type of vulnerability directly impacts the confidentiality, integrity, and availability of the affected system, potentially leading to service disruption, data loss, and regulatory compliance violations.
Mitigation strategies for CVE-2005-2404 must address both immediate remediation and long-term security improvements. The primary solution involves implementing proper input validation and parameterized queries to ensure that user-supplied data cannot interfere with SQL command execution. Organizations should immediately patch or upgrade to a version of Sendcard that addresses this vulnerability, as the original version contains no built-in protections against SQL injection attacks. Security best practices dictate the implementation of prepared statements or parameterized queries for all database interactions, which aligns with ATT&CK technique T1071.004 for application layer attacks. Additional defensive measures include input sanitization, output encoding, and the principle of least privilege for database accounts. Network-level protections such as web application firewalls and intrusion detection systems can provide additional layers of defense, though they should not be considered substitutes for proper code-level fixes. The vulnerability also highlights the importance of regular security audits and code reviews to identify and remediate similar issues in legacy applications.
