CVE-2025-15447 identifies a SQL injection vulnerability in the Seeyon Zhiyuan OA Web Application System, a widely used office automation platform. The vulnerability resides in the /assetsGroupReport/assetsService.jsp file, where the unitCode parameter is improperly sanitized, allowing attackers to inject malicious SQL statements. This injection flaw can be exploited remotely without authentication or user interaction, enabling attackers to manipulate backend databases. Potential impacts include unauthorized data disclosure, data modification, or deletion, and possibly disruption of application availability. The vulnerability affects version 20251223 of the software, with no patches currently available as the vendor has not responded to disclosure. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges or user interaction required, and low impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are reported in the wild, public disclosure increases the risk of exploitation. The lack of vendor response and patch availability heightens the urgency for organizations to implement mitigations. Given the nature of OA systems, which often handle sensitive organizational data and workflows, exploitation could lead to significant operational and data security consequences.

For European organizations using Seeyon Zhiyuan OA Web Application System, this vulnerability poses a risk of unauthorized access to sensitive corporate data, including financial, personnel, and operational information. Successful exploitation could lead to data breaches, loss of data integrity, and potential service disruptions impacting business continuity. Given the remote and unauthenticated nature of the exploit, attackers could leverage this vulnerability to gain footholds within networks, escalate privileges, or move laterally. The medium severity rating reflects moderate impact potential; however, the actual damage depends on the data stored and the criticality of the OA system within the organization. Regulatory implications under GDPR may arise if personal data is compromised, leading to legal and financial penalties. The absence of vendor patches increases exposure time, necessitating proactive defensive measures. Additionally, organizations relying on this software for critical workflows may experience operational delays or reputational damage if exploited.

European organizations should immediately audit their Seeyon Zhiyuan OA Web Application deployments to identify affected versions (up to 20251223). In the absence of official patches, implement strict input validation and sanitization on the unitCode parameter at the web application firewall (WAF) or reverse proxy level to block malicious SQL payloads. Employ parameterized queries or prepared statements in custom integrations if source code access is available. Restrict network access to the vulnerable endpoint by limiting exposure to trusted internal networks or VPNs. Monitor logs for unusual SQL errors or suspicious query patterns indicative of injection attempts. Deploy intrusion detection/prevention systems (IDS/IPS) with updated signatures targeting this vulnerability. Conduct regular backups and ensure recovery procedures are tested to mitigate potential data loss. Engage with the vendor for updates and consider alternative OA solutions if remediation is delayed. Finally, raise user awareness about potential phishing or social engineering attempts that could accompany exploitation efforts.
