CVE-2025-34039: CWE-306 Missing Authentication for Critical Function in Yonyou Co., Ltd. UFIDA NC
A code injection vulnerability exists in Yonyou UFIDA NC v6.5 and prior due to the exposure of the BeanShell testing servlet (bsh.servlet.BshServlet) without proper access controls. The servlet allows unauthenticated remote attackers to execute arbitrary Java code via the bsh.script parameter. This can be exploited to run system commands and ultimately gain full control over the target server. The issue is rooted in a third-party JAR component bundled with the application, and the servlet is accessible without authentication on vulnerable installations. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-05 UTC.
AI Analysis
Technical Summary
Yonyou UFIDA NC v6.5 and prior versions include an exposed BeanShell testing servlet without authentication, enabling unauthenticated attackers to inject and execute arbitrary Java code remotely through the bsh.script parameter. This vulnerability is classified as CWE-306 (Missing Authentication for Critical Function) and has a CVSS 4.0 base score of 10.0, indicating critical severity. The root cause is a third-party JAR component bundled with the application. Exploitation has been confirmed in the wild by Shadowserver Foundation as of February 2025. The product is not a cloud service, and no official patch or fix has been documented or linked by the vendor as of the publication date.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary Java code and system commands on the affected server, potentially leading to full system compromise. This can result in unauthorized control over the server hosting Yonyou UFIDA NC, data breaches, and disruption of business operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting network access to the affected servlet, disabling the BeanShell testing servlet if possible, or applying other access control measures to prevent unauthenticated access. Monitor vendor communications for updates on patches or official mitigations.
