CVE-2025-34039Yonyou NC BeanShell Command Injection
Critical 10.0
In plain English
A critical-severity missing authentication in UFIDA NC from Yonyou Co., Ltd.. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.6% (higher than 46% of all known vulnerabilities).
Official 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.
