Overview
CVE-2025-56396 describes a privilege escalation vulnerability discovered in RuoYi version 4.8.1. This vulnerability allows attackers to gain elevated privileges within the system, potentially leading to unauthorized access and control.
Technical Details
The vulnerability stems from a flaw in the access control mechanism within RuoYi 4.8.1. Specifically, the system incorrectly grants permissions based on the owning department of a user or resource, rather than the user’s actual assigned role and permissions. If the owning department has higher privileges than the active user, the user can inherit these higher privileges, effectively escalating their access rights. Further technical details are available in the linked references.
CVSS Analysis
Currently, the CVSS score and severity level for CVE-2025-56396 are listed as N/A. A proper CVSS score is pending full analysis and determination of exploitability and impact. We will update this section as soon as more information becomes available.
Possible Impact
The potential impact of this vulnerability is significant. A successful exploit could allow an attacker to:
- Gain unauthorized access to sensitive data.
- Modify system configurations.
- Execute arbitrary code.
- Compromise the integrity and availability of the RuoYi application and the underlying system.
- Create new administrative accounts.
Mitigation or Patch Steps
To mitigate this vulnerability, we recommend the following steps:
- Upgrade to a patched version: The most effective solution is to upgrade to a version of RuoYi that addresses this vulnerability. Check the RuoYi project’s website or release notes for the latest version.
- Review User Permissions: As a temporary measure, carefully review and restrict user permissions within RuoYi. Ensure that users only have the minimum necessary privileges required for their roles. Pay special attention to departmental permissions.
- Monitor System Activity: Closely monitor system activity for any suspicious behavior that may indicate an attempted exploit.
