The CVE-2017-7879 vulnerability represents a critical sql injection flaw in flatCore version 1.4.6 that fundamentally compromises database security. This vulnerability falls under the common weakness enumeration category CWE-89, which specifically addresses sql injection vulnerabilities where untrusted data is incorporated into sql commands without proper sanitization or validation. The flaw exists within the application's handling of user input parameters that are directly concatenated into sql queries, creating an attack surface where malicious actors can manipulate database operations through crafted input sequences. The vulnerability specifically affects the content database reading functionality, allowing unauthorized access to sensitive information stored within the application's backend database system.
The technical implementation of this vulnerability stems from improper input validation mechanisms within flatCore's database interaction layers. When users submit data through various application interfaces, the system fails to properly escape or parameterize sql query components, enabling attackers to inject malicious sql code that executes with the privileges of the database user account. This occurs because the application relies on string concatenation methods rather than prepared statements or parameterized queries to construct sql commands. Attackers can exploit this by manipulating query parameters to bypass authentication checks, extract database schemas, retrieve user credentials, and access confidential content stored in the database. The vulnerability is particularly dangerous as it allows for complete database enumeration and potential data exfiltration without requiring elevated privileges or authentication.
The operational impact of CVE-2017-7879 extends far beyond simple data theft, as it provides attackers with comprehensive access to the application's entire content database. This vulnerability can be leveraged to extract user accounts, personal information, application configuration details, and potentially sensitive business data that may include intellectual property or customer records. The attack surface is particularly concerning because flatCore is a content management system that typically handles sensitive information, making the database access particularly valuable to threat actors. The vulnerability can be exploited through various attack vectors including web application interfaces, api endpoints, or direct parameter manipulation, allowing for both automated scanning and targeted manual exploitation approaches. This access level enables attackers to perform data manipulation, create backdoor accounts, and potentially establish persistent access to the compromised system.
Mitigation strategies for CVE-2017-7879 must address both immediate remediation and long-term security improvements within the flatCore application framework. The primary solution involves implementing proper input validation and parameterized query construction throughout the application codebase, ensuring that all user-supplied data is properly escaped or parameterized before database interaction. Organizations should immediately upgrade to flatCore version 1.4.7 or later, which contains the necessary patches to address the sql injection vulnerability. Security measures should include input sanitization at multiple layers, implementation of web application firewalls, and regular security audits to identify similar vulnerabilities. The mitigation approach aligns with attack technique tt0001 in the attack framework, which focuses on command and control communications and data exfiltration through database access. Additionally, organizations should implement database access logging, monitoring for unusual query patterns, and regular penetration testing to ensure the vulnerability has been properly addressed and to identify potential related issues in the application's security architecture.
