The vulnerability identified as CVE-2019-10910 affects the Symfony framework's dependency injection component and represents a critical security flaw that could enable remote code execution through SQL injection attacks. This vulnerability exists in multiple versions of Symfony including 2.7.x before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7. The flaw specifically manifests when service identifiers in the dependency injection container accept user-controllable input without proper sanitization or validation mechanisms.
The technical root cause of this vulnerability lies within how Symfony's dependency injection container processes service identifiers that originate from user input. When applications utilize dynamic service resolution where service names are constructed from user-supplied data, the framework fails to adequately sanitize these inputs before incorporating them into database queries or executing code. This creates a pathway for attackers to manipulate the service resolution process and inject malicious payloads that can ultimately result in SQL injection vulnerabilities. The vulnerability maps to CWE-89 SQL Injection and CWE-94 Code Injection, both of which are classified as high-risk security flaws in the Common Weakness Enumeration catalog. The attack vector aligns with ATT&CK technique T1059.006 Command and Scripting Interpreter: PowerShell, as malicious code injection can occur through command execution pathways.
The operational impact of CVE-2019-10910 is severe and multifaceted, potentially allowing attackers to gain complete control over affected applications. An attacker who successfully exploits this vulnerability can execute arbitrary code on the target system, potentially leading to data breaches, system compromise, and full application control. The SQL injection aspect means that attackers could extract sensitive data from databases, modify or delete information, and potentially escalate privileges within the application environment. Organizations running affected Symfony versions face significant risk exposure, particularly those with web applications that accept user input for service identification or configuration parameters. The vulnerability affects a wide range of applications since Symfony is a widely-used PHP framework with numerous enterprise implementations.
Mitigation strategies for CVE-2019-10910 require immediate action to upgrade affected Symfony installations to patched versions. Organizations should prioritize updating their Symfony framework to the latest stable releases that address this vulnerability, specifically versions 2.7.51, 2.8.50, 3.4.26, 4.1.12, and 4.2.7 or later. Additionally, developers should implement proper input validation and sanitization for all service identifiers that accept user input, ensuring that any dynamic service name construction includes proper escaping or parameterization. Security measures should include implementing strict access controls for service resolution mechanisms and monitoring application logs for suspicious service identifier patterns. Organizations should also consider implementing web application firewalls and runtime application self-protection technologies to detect and prevent exploitation attempts. The remediation process should include comprehensive code reviews to identify all instances where user input might influence service resolution, and implementing proper security testing procedures including dynamic application security testing to validate the effectiveness of mitigation measures.
