The vulnerability identified as CVE-2013-6929 represents a critical SQL injection flaw affecting Cybozu Garoon versions 3.7 SP2 and earlier. This security weakness resides within the application's API handling mechanism, where insufficient input validation permits malicious actors to manipulate database queries through crafted API requests. The vulnerability specifically impacts authenticated users who possess valid credentials within the Garoon environment, creating a scenario where legitimate access can be exploited for unauthorized database operations.
This SQL injection vulnerability stems from improper sanitization of user-supplied data within the API endpoints. When authenticated users submit crafted input through API calls, the application fails to adequately escape or validate special characters that could alter the intended SQL query structure. The flaw allows attackers to inject malicious SQL code that executes with the privileges of the database user account associated with the Garoon application. According to CWE-89, this classification identifies the vulnerability as a direct result of inadequate input validation and improper SQL query construction, where user-controllable data is directly incorporated into database queries without appropriate sanitization measures.
The operational impact of this vulnerability extends beyond simple data theft, as it enables attackers to execute arbitrary SQL commands on the underlying database system. Successful exploitation could result in complete database compromise, including data extraction, modification, or deletion of sensitive corporate information. The authenticated nature of the vulnerability means that attackers do not require direct network access to the database server, as they can leverage their legitimate API access to perform malicious operations. This scenario aligns with ATT&CK technique T1078 which describes valid accounts as a means for initial access and privilege escalation within target environments.
Organizations utilizing affected Cybozu Garoon versions face significant risk of data breaches and system compromise when this vulnerability remains unaddressed. The SQL injection attack vector allows for extensive database manipulation, potentially exposing confidential business information, user credentials, and operational data. The vulnerability's remote execution capability means that attackers can exploit this weakness from any location with network access to the Garoon API endpoints, making it particularly dangerous for organizations with remote workers or distributed access patterns. Security professionals should note that this vulnerability demonstrates the critical importance of input validation and proper database query construction in preventing injection attacks that can lead to complete system compromise. Remediation efforts must focus on implementing proper parameterized queries, input validation, and comprehensive API security controls to prevent similar vulnerabilities from occurring in future versions of the application.
