The vulnerability identified as CVE-2013-6930 represents a critical SQL injection flaw within the page-navigation functionality of Cybozu Garoon versions spanning multiple release branches. This vulnerability affects a broad range of product versions including 2.0.x, 2.1.x, 2.5.x, 3.0.x, 3.5.x, and 3.7.x prior to 3.7.3, indicating a widespread issue that persisted across several major releases. The flaw exists in the way the application processes navigation parameters, creating an attack surface where malicious input can be directly translated into database queries without proper sanitization or parameterization. This vulnerability is particularly concerning because it operates within the navigation implementation, which is a core functionality that users frequently interact with during normal application usage, making exploitation both accessible and potentially devastating.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the page-navigation component of the Garoon application. When users navigate through the application's interface, specific parameters are passed to the backend database queries, and these parameters are not properly escaped or parameterized before being incorporated into SQL statements. This allows authenticated attackers to inject malicious SQL code that gets executed within the database context, potentially enabling full database compromise. The vulnerability operates at the application layer where user-supplied data flows directly into database operations, creating a classic SQL injection vector. According to CWE classification, this represents a CWE-89: Improper Neutralization of Special Elements used in an SQL Command, which is one of the most prevalent and dangerous web application vulnerabilities. The attack requires only authenticated access, which significantly reduces the barrier to exploitation compared to vulnerabilities requiring additional reconnaissance or privilege escalation.
The operational impact of this vulnerability extends far beyond simple data theft, as successful exploitation can result in complete database compromise, data exfiltration, and potential lateral movement within the network infrastructure. An attacker with valid credentials can leverage this vulnerability to execute arbitrary SQL commands, potentially gaining access to sensitive user information, authentication credentials, and business-critical data stored within the Garoon application's database. The implications are particularly severe given that Garoon is typically used for enterprise collaboration and document management, making the compromised data potentially highly valuable. The vulnerability's persistence across multiple versions suggests that organizations running affected versions may have been exposed for extended periods without detection, creating a significant window for potential exploitation. From an ATT&CK framework perspective, this vulnerability maps to T1071.005: Application Layer Protocol: Web Protocols and T1566.001: Credential Access: Phishing, as exploitation involves manipulating application navigation to achieve unauthorized database access.
Organizations affected by this vulnerability should prioritize immediate remediation through official vendor patches or updates to versions that address the SQL injection flaw. The mitigation strategy should include implementing proper input validation and parameterized queries throughout the application's navigation components, ensuring that all user-supplied parameters are properly sanitized before database interaction. Network segmentation and access controls should be reviewed to limit the impact of potential exploitation, while monitoring systems should be enhanced to detect unusual database query patterns that might indicate SQL injection attempts. Security teams should also conduct comprehensive vulnerability assessments across all instances of the affected software versions to identify and remediate similar issues within the broader application ecosystem. Additionally, implementing web application firewalls and database activity monitoring solutions can provide additional layers of protection against exploitation attempts and help establish baseline behaviors for detecting anomalous database access patterns that could indicate successful exploitation of this vulnerability.
