Vulnerability from fkie_nvd - Published: 2021-11-19 16:15 - Updated: 2026-06-17 03:36
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
Applications using both `spring-cloud-netflix-hystrix-dashboard` and `spring-boot-starter-thymeleaf` expose a way to execute code submitted within the request URI path during the resolution of view templates. When a request is made at `/hystrix/monitor;[user-provided data]`, the path elements following `hystrix/monitor` are being evaluated as SpringEL expressions, which can lead to code execution.
