What is CVE-2025-34039?

A code injection vulnerability exists in Yonyou UFIDA NC versions v6.5 and earlier due to improperly secured access to the BeanShell testing servlet (bsh.servlet.BshServlet). This flaw enables unauthenticated remote attackers to exploit the servlet, allowing them to execute arbitrary Java code through the bsh.script parameter. Consequently, attackers can run system commands, potentially gaining full control over the affected server. The root cause is linked to a third-party JAR component included in the application, which lacks appropriate access controls for the servlet.

Affected Version(s)

UFIDA NC 0 <= 6.5

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
