MapSVG versions prior to 8.14.0 contain a critical unauthenticated sql injection vulnerability that allows remote attackers to execute arbitrary database commands without requiring any authentication credentials. This vulnerability exists within the plugin's handling of user input parameters, specifically in the way it processes and sanitizes data submitted through various api endpoints. The flaw stems from inadequate input validation and improper parameter binding in the backend database queries, creating a direct path for malicious sql payloads to be executed within the database context. Attackers can exploit this vulnerability by crafting specially formatted requests that bypass normal security controls and inject malicious sql code into the application's query execution flow.
The technical implementation of this vulnerability involves the plugin's failure to properly escape or parameterize user-supplied data before incorporating it into sql statements. When legitimate users interact with mapsvg functionality, their input is directly concatenated into database queries without proper sanitization mechanisms. This creates a classic sql injection scenario where an attacker can manipulate the intended query structure by injecting sql syntax elements such as union select statements, comment characters, or other payload constructs. The vulnerability affects multiple api endpoints within the plugin that handle map data retrieval, configuration updates, and user management functions, making it particularly dangerous as it provides broad access to the underlying database operations.
The operational impact of this vulnerability is severe and multifaceted, potentially allowing attackers to extract sensitive information from the database including user credentials, personal data, and application configurations. Depending on the database permissions assigned to the web application's database user account, attackers might also be able to modify or delete data, execute administrative commands, or even escalate privileges within the system. The unauthenticated nature of this vulnerability means that any visitor to a website using an affected mapsvg plugin version can potentially exploit it without requiring login credentials or prior access to the system. This makes the attack surface extremely broad and increases the likelihood of successful exploitation across various web applications.
Security practitioners should immediately update to MapSVG version 8.14.0 or later to remediate this vulnerability, as no known workarounds exist that can safely mitigate the issue without patching the core plugin functionality. Organizations running affected versions should conduct immediate inventory checks to identify all installations and apply updates as soon as possible. Additional defensive measures include implementing web application firewalls with sql injection detection rules, monitoring database logs for suspicious query patterns, and conducting thorough security audits of all plugins and themes in use. This vulnerability aligns with CWE-89 which specifically addresses sql injection flaws, and represents a clear violation of the principle of least privilege as outlined in cybersecurity best practices. The ATT&CK framework categorizes this as a command and control activity under the technique of SQL injection where adversaries leverage database vulnerabilities to gain unauthorized access to system resources and data. Organizations should also consider implementing automated patch management systems to ensure timely deployment of security updates across all web applications and plugins to prevent similar incidents in the future.
