RCE Code Injection Ruoyi Vue Plus

Description

The snailjob component in RuoYi-Vue-Plus versions 5.5.1 and earlier, interface /snail-job/workflow/check-node-expression can execute QLExpress expressions, but it does not filter user input, allowing attackers to use the File class to perform arbitrary file reading and writing.

Analysis

RuoYi-Vue-Plus (through 5.5.1) allows arbitrary file read/write through QLExpress expression evaluation in the snailjob workflow node checker. Attackers can use the File class to access any file on the server. PoC available.

Technical Context

The /snail-job/workflow/check-node-expression endpoint evaluates QLExpress expressions without filtering dangerous classes (CWE-94). Attackers can use java.io.File and related classes to read sensitive files (application.yml, database credentials) or write malicious files.

Affected Products

RuoYi-Vue-Plus through 5.5.1

Remediation

Update RuoYi-Vue-Plus. Implement expression sandboxing that blocks File, Runtime, Process, and other dangerous classes.
