FKIE_CVE-2025-34039

Vulnerability from fkie_nvd - Published: 2025-06-24 02:15 - Updated: 2025-11-20 22:15
Severity ?
10.0 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
Summary
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.

El servlet permite a atacantes remotos no autenticados ejecutar c\u00f3digo Java arbitrario mediante el par\u00e1metro bsh.script. Esto puede explotarse para ejecutar comandos del sistema y, en \u00faltima instancia, obtener el control total del servidor objetivo. El problema se origina en un componente JAR de terceros incluido en la aplicaci\u00f3n, y el servlet es accesible sin autenticaci\u00f3n en instalaciones vulnerables."
