The vulnerability identified as CVE-2017-7410 represents a critical security flaw in WebsiteBaker versions 2.10.0 and earlier, specifically targeting the account signup functionality. This issue manifests as multiple SQL injection vulnerabilities within the account/signup.php and account/signup2.php scripts, creating a pathway for remote attackers to manipulate the underlying database through crafted input parameters. The vulnerability affects the username and display_name parameters, which are processed without adequate input validation or sanitization, allowing malicious actors to inject arbitrary SQL commands that execute within the database context.
The technical exploitation of this vulnerability occurs through improper handling of user-supplied input in the web application's registration process. When users attempt to create accounts through the signup scripts, the application fails to implement proper parameterized queries or input sanitization mechanisms. Attackers can construct malicious payloads that bypass normal input validation, enabling them to inject SQL syntax directly into the database queries. This flaw falls under the CWE-89 category of SQL Injection, which is classified as a critical weakness in software security. The vulnerability allows for complete database compromise, enabling attackers to extract sensitive information, modify user accounts, or even escalate privileges within the application environment.
The operational impact of CVE-2017-7410 extends beyond simple data theft, as it provides attackers with persistent access to the application's database infrastructure. Successful exploitation could result in unauthorized user account creation, data manipulation, and potential lateral movement within the network if the database server hosts additional services. The vulnerability is particularly dangerous because it affects the registration process, which is a core functionality that legitimate users frequently interact with, making the attack surface more accessible. This weakness can be exploited through the standard web application attack vectors documented in the MITRE ATT&CK framework under the T1190 technique for exploitation of remote services, specifically targeting web application vulnerabilities.
Mitigation strategies for this vulnerability require immediate implementation of proper input validation and parameterized queries throughout the affected scripts. Organizations should implement prepared statements or parameterized queries for all database interactions, ensuring that user input is treated as data rather than executable code. Additionally, the application should enforce strict input sanitization and validation, rejecting any input that contains suspicious SQL patterns or characters. The recommended remediation aligns with industry best practices outlined in the OWASP Top Ten and follows the principle of least privilege by ensuring database connections use minimal required permissions. Regular security assessments and input validation testing should be implemented to prevent similar vulnerabilities from emerging in future versions of the software.
