Detailsinfo

A vulnerability, which was classified as very critical, has been found in Yonyou UFIDA NC up to 6.5. This issue affects some unknown processing of the component JAR Component Handler. The manipulation of the argument bsh.script with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at cnblogs.com. The identification of this vulnerability is CVE-2025-34039 since 04/15/2025. The exploitation is known to be easy. The attack may be initiated remotely.
