CVE-2025-63740 is an SQL Injection vulnerability identified in the Xinhu Rainrock RockOA 2.7.0 office automation platform, specifically in the getselectdataAjax function located in the inputAction.php file. The vulnerability arises from improper sanitization of the actstr parameter, which is used in a database query without adequate validation or parameterization. This allows an attacker to inject malicious SQL code, enabling unauthorized retrieval of sensitive information such as administrator usernames, password hashes, database structure, and other critical data stored within the backend database. The exploitation does not require prior authentication, increasing the attack surface and risk. While no public exploits have been reported yet, the vulnerability's presence in a widely used office automation system poses a significant risk. The lack of a published patch or mitigation guidance increases urgency for organizations to implement protective measures. SQL Injection vulnerabilities are among the most severe web application security issues because they can lead to data breaches, privilege escalation, and full system compromise. The RockOA platform is used primarily in enterprise environments for workflow and document management, meaning that exploitation could disrupt business operations and leak confidential corporate data. The vulnerability was reserved in late October 2025 and published in December 2025, indicating recent discovery and disclosure. The absence of a CVSS score requires an independent severity assessment based on impact and exploitability factors.

For European organizations, exploitation of CVE-2025-63740 could result in unauthorized disclosure of sensitive corporate data, including administrator credentials and password hashes, which could lead to further compromise of internal systems. The breach of database structure information can facilitate more sophisticated attacks, including privilege escalation and lateral movement within networks. Organizations relying on RockOA 2.7.0 for office automation and document management may face operational disruptions, data integrity issues, and reputational damage. Given that no authentication is required to exploit this vulnerability, attackers can remotely target vulnerable systems with relative ease. This increases the risk of widespread attacks, especially in sectors with high-value data such as finance, government, and critical infrastructure. The lack of a patch means organizations must rely on immediate mitigations to prevent exploitation. The impact extends beyond data confidentiality to potentially affect availability if attackers leverage the vulnerability to execute destructive SQL commands. Overall, the vulnerability poses a high risk to European enterprises using this software, particularly those with sensitive or regulated data.

European organizations using Xinhu Rainrock RockOA 2.7.0 should immediately conduct an inventory to identify affected instances. Until an official patch is released, implement web application firewall (WAF) rules specifically designed to detect and block SQL Injection attempts targeting the actstr parameter in inputAction.php. Employ input validation and sanitization at the application level to reject suspicious input patterns. Restrict database user permissions associated with the web application to the minimum necessary to limit the impact of any injection. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. Consider isolating or segmenting affected systems to reduce lateral movement risk. Engage with the vendor or community to obtain updates or patches as soon as they become available. Conduct penetration testing focused on SQL Injection vectors to verify the effectiveness of mitigations. Educate developers and administrators about secure coding practices to prevent similar vulnerabilities in future releases. Finally, maintain regular backups of critical data to enable recovery in case of compromise.
