Exploitation Summary
CVE-2025-34039 has been observed exploited in the wild (reported by VulnCheck KEV).
Description
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.
