CVE-2018-25394 in R10 GreenBee
Summary
by MITRE • 05/29/2026
Kados R10 GreenBee contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the release_id parameter of boards_buttons/update_release.php. The release_id value is concatenated directly into SQL statements without sanitization, allowing attackers to send a crafted GET request with a UNION-based payload to extract sensitive database information including the current user, database name, and DBMS version.

The Kados R10 GreenBee system presents a critical SQL injection vulnerability that fundamentally compromises database security through improper input validation mechanisms. This vulnerability exists within the boards_buttons/update_release.php endpoint where the release_id parameter receives user input without adequate sanitization or parameterization. The flaw represents a classic example of insecure database query construction where attacker-controlled data directly influences SQL statement composition, creating an exploitable pathway for unauthorized database access. The vulnerability affects the system's authentication and authorization mechanisms by allowing unauthenticated attackers to bypass normal access controls and directly interact with underlying database structures.
The technical implementation of this vulnerability follows standard SQL injection patterns where the release_id parameter is directly concatenated into SQL queries without proper input filtering or prepared statement usage. This design flaw enables attackers to inject malicious SQL code through crafted GET requests that leverage UNION-based payloads to extract sensitive information from the database. The vulnerability's exploitation demonstrates a clear path from initial access to data exfiltration, as attackers can construct queries that union their malicious input with legitimate database queries to retrieve system metadata including current user credentials, database schema information, and underlying database management system version details. The vulnerability's impact extends beyond simple information disclosure to potentially enable further attack vectors including privilege escalation and data manipulation.
The operational consequences of this vulnerability are severe for organizations relying on Kados R10 GreenBee systems, as it creates an immediate risk of unauthorized data access and potential system compromise. Attackers can leverage this vulnerability to extract sensitive user credentials, application configuration details, and database structure information that could facilitate additional attacks within the network infrastructure. The unauthenticated nature of the exploit means that any external party can potentially access the database without requiring legitimate credentials, making this vulnerability particularly dangerous for systems with exposed web interfaces. This weakness directly violates security principles of least privilege and input validation, creating a persistent threat that remains active until proper patching or mitigation measures are implemented.
Organizations should implement immediate mitigations including input validation and parameterized queries to address this vulnerability. The recommended approach involves implementing proper input sanitization mechanisms that filter or escape special characters in user-supplied parameters before database processing. Additionally, employing prepared statements or parameterized queries ensures that user input cannot alter the fundamental structure of SQL statements. Network-level protections such as web application firewalls and access controls should also be implemented to limit exposure of vulnerable endpoints. This vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws and represents a clear violation of the principle of input validation as outlined in NIST SP 800-160. The attack pattern follows typical MITRE ATT&CK techniques for credential access and data extraction, making it a significant concern for enterprise security posture and compliance requirements.
