The vulnerability identified as CVE-2015-10076 affects the Shaarlier application version 1.2.2 and earlier, representing a critical security flaw in the tag handling functionality. This issue resides within the Tag Handler component of the application, specifically in the createTag function located in app/src/main/java/com/dimtion/shaarlier/TagsSource.java. The vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly handle user-supplied data before incorporating it into database queries. The flaw manifests as a SQL injection vulnerability that allows malicious actors to execute arbitrary SQL commands against the underlying database system.
The technical implementation of this vulnerability occurs when the application processes tag creation requests without properly escaping or parameterizing user input. When users submit tags through the interface, the createTag function directly incorporates these inputs into SQL query construction without appropriate sanitization measures. This design flaw enables attackers to inject malicious SQL payloads that can manipulate the database, potentially leading to unauthorized data access, modification, or deletion. The vulnerability specifically targets the database interaction layer where tag metadata is stored, making it particularly dangerous as it could compromise the entire tag management system and associated user data.
The operational impact of this SQL injection vulnerability extends beyond simple data manipulation to potentially compromise the entire application infrastructure. Attackers could leverage this vulnerability to extract sensitive information from the database, including user credentials, personal data, or application configuration details. The severity classification as critical indicates that the vulnerability could be exploited remotely without requiring authentication, making it particularly dangerous for applications handling user-generated content. The vulnerability affects not just the tag functionality but could potentially serve as a foothold for more extensive attacks against the application's database layer, potentially leading to complete system compromise.
Security mitigations for this vulnerability primarily involve upgrading to version 1.2.3, which includes the patch identified by the commit hash 3d1d9b239d9b3cd87e8bed45a0f02da583ad371e. This upgrade addresses the core issue by implementing proper input validation and parameterized query construction in the Tag Handler component. Organizations should also consider implementing additional security controls such as web application firewalls, database query monitoring, and regular security assessments. The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws, and represents a clear violation of secure coding practices that should be addressed through proper input sanitization and parameterized database queries. This issue also maps to ATT&CK technique T1071.004, which covers application layer protocol manipulation, highlighting the need for comprehensive security measures beyond simple patching.
