CyberRota Analysis
AI-GeneratedSpringBlade versions 2.7.3 through 3.5.0 are vulnerable to a privilege escalation flaw that allows authenticated users to create system administrator accounts via an unprotected internal Feign user-creation endpoint. This vulnerability can be exploited by leveraging a weak authentication filter that fails to validate user roles, combined with a hardcoded JWT signing key, enabling attackers to escalate privileges and gain unauthorized access to sensitive data. Organizations using affected versions should prioritize patching this vulnerability to prevent potential cross-tenant data pollution and persistent backdoor access.

Original NVD Description
SpringBlade versions from 2.7.3 up to but not including 5.0.0 contain a privilege escalation vulnerability that allows authenticated attackers to create system administrator accounts by sending crafted POST requests to an unprotected internal Feign user-creation endpoint exposed via @RestController without authorization checks. Attackers can exploit the gateway's authentication filter, which only validates JWT parsing without verifying user roles or caller identity, and leverage a hardcoded JWT signing key embedded in publicly available JARs to forge tokens and escalate privileges from a low-privilege user to administrator, enabling cross-tenant data pollution and persistent backdoor access.
