CVE-2025-70985: RuoYi Access Control Bypass Vulnerability

CVE-2025-70985 Overview

CVE-2025-70985 is a critical access control vulnerability affecting the update function in RuoYi v4.8.2, a popular open-source Java EE rapid development framework. This incorrect access control flaw allows unauthorized attackers to arbitrarily modify data outside of their intended scope, potentially leading to widespread data manipulation and compromise of application integrity.

Critical Impact

Unauthorized attackers can exploit this vulnerability to modify arbitrary data beyond their authorized scope, potentially compromising data integrity and confidentiality across the entire application.

Technical Details for CVE-2025-70985

Vulnerability Analysis

This vulnerability stems from improper access control (CWE-284) within the update function of the RuoYi framework. The flaw allows attackers to bypass authorization checks and modify data records that should be restricted to other users or administrative roles. This is classified as a Broken Access Control vulnerability, specifically enabling horizontal and potentially vertical privilege escalation through data manipulation.

The vulnerability is particularly dangerous because it can be exploited remotely over the network without requiring any prior authentication or user interaction. An attacker can craft malicious requests to the update function that manipulate data belonging to other users or system components, effectively bypassing the application's intended authorization boundaries.

Root Cause

The root cause of CVE-2025-70985 lies in insufficient authorization validation within the update function implementation. The application fails to properly verify that the requesting user has the necessary permissions to modify the targeted data record before processing the update operation. This missing access control check allows any authenticated or unauthenticated user to manipulate records outside their designated scope by directly referencing data identifiers belonging to other users or protected system resources.

Attack Vector

The vulnerability is exploitable via network-based attacks with low complexity requirements. An attacker can target the update function endpoint by crafting HTTP requests that specify data identifiers outside their authorized scope. The attack does not require authentication or user interaction, making it highly accessible to remote adversaries.

The exploitation process involves identifying the vulnerable update endpoint and manipulating request parameters to target records belonging to other users or protected system entities. Due to the missing authorization checks, the application processes these malicious requests and applies the unauthorized modifications.

Detection Methods for CVE-2025-70985

Indicators of Compromise

• Unexpected modifications to user data or system configurations that cannot be attributed to authorized users
• Log entries showing update requests targeting data identifiers outside the requesting user's normal scope
• Unusual patterns of update requests from a single source targeting multiple different user records
• Anomalous changes to sensitive data fields that bypass normal business workflows

Detection Strategies

• Implement application-level logging to capture all update function calls with full request parameters and user context
• Deploy web application firewall (WAF) rules to monitor for suspicious parameter manipulation patterns in update requests
• Configure database audit logging to track modification operations and correlate them with application-level authentication
• Use behavioral analysis to detect users attempting to access or modify resources outside their typical access patterns

Monitoring Recommendations

• Enable comprehensive audit logging for all data modification operations within the RuoYi application
• Set up alerts for update operations where the target record owner does not match the authenticated user
• Monitor for spikes in update request failures or authorization errors that may indicate exploitation attempts
• Implement real-time monitoring of sensitive data tables for unauthorized modifications

How to Mitigate CVE-2025-70985

Immediate Actions Required

• Upgrade RuoYi to the latest available version that addresses this access control vulnerability
• Review and audit all data modification operations that occurred during the exposure window
• Implement additional authorization checks at the application layer to validate user permissions before processing updates
• Consider temporarily restricting access to the vulnerable update functionality until a patch is applied

Patch Information

Organizations using RuoYi v4.8.2 should monitor the official project repositories for security updates. Refer to the GitHub RuoYi Project Repository and Gitee RuoYi Project Repository for the latest releases and security advisories. The Gitee RuoYi Issue Discussion provides additional context on the vulnerability and potential remediation guidance.

Workarounds

• Implement a custom authorization filter or interceptor that validates record ownership before allowing update operations
• Deploy network-level access controls to restrict update endpoint access to trusted IP ranges or authenticated sessions only
• Add server-side validation to ensure users can only modify records within their authorized data scope
• Consider implementing row-level security at the database layer as an additional defense-in-depth measure

# Example: Restrict access to update endpoints via web server configuration
# Apache configuration example
<Location "/system/update">
    Require valid-user
    Require ip 10.0.0.0/8 192.168.0.0/16
</Location>
