SQL Injection in RainyGao DocSys Database Management

A vulnerability was detected in RainyGao DocSys up to 2.02.85. The impacted element is the function BaseController.createDBForMysql of the file BaseController.java of the component Database Management. The manipulation of the argument url results in sql injection. The attack can be executed remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

Casky was already ahead

This CVE exploits attack patterns that Casky's 323matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

RainyGao DocSys versions up to 2.02.85 contain a critical SQL injection vulnerability in the BaseController.createDBForMysql function, where unsanitized URL parameters are passed directly into database queries. This vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion of sensitive information stored in the database. Organizations using DocSys for document management and database administration are at immediate risk, particularly those exposed to untrusted networks. The public availability of exploit code and the vendor's lack of response elevate the urgency of remediation.

Casky's 323 matched skills leverage Claude AI with extended reasoning to identify the attack chain mapped to MITRE techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance via public vulnerability databases) combined with exploitation patterns. Practitioners would observe detection alerts for CWE-74 (Improper Neutralization of Special Elements in Output) and CWE-89 (SQL Injection) signatures in their findings—specifically anomalous SQL query patterns containing URL-derived payloads, unexpected database connection attempts to the createDBForMysql endpoint, and parameter manipulation attempts in database configuration requests. The skills framework correlates these indicators with threat actor behavior, enabling practitioners to distinguish between legitimate database configuration activities and malicious SQL injection probes before they compromise the database layer.
