Description Preview
A Cross-Site Request Forgery (CSRF) vulnerability was discovered in YzmCMS version 5.8. This vulnerability allows attackers to trick authenticated administrators into adding new member user accounts without their knowledge or consent. The vulnerability exists in the member account creation functionality accessible via the member/member/add.html endpoint. By crafting a malicious webpage and convincing an administrator to visit it while logged in to YzmCMS, an attacker can execute unauthorized account creation operations with the administrator's privileges.
Overview
YzmCMS V5.8 suffers from a Cross-Site Request Forgery (CSRF) vulnerability in its member account management system. The vulnerability occurs because the application fails to implement proper CSRF protection mechanisms when processing requests to add new member accounts. When an administrator with sufficient privileges visits a malicious website while authenticated to the YzmCMS admin panel, the attacker can force the administrator's browser to submit requests that create new member accounts. This could lead to unauthorized access to the system, as attackers could create accounts with elevated privileges that they can later use to access sensitive information or perform additional malicious actions.
Remediation
To remediate this vulnerability, administrators of YzmCMS V5.8 systems should:
- Update to the latest version of YzmCMS if a patched version is available.
- Implement proper CSRF protection mechanisms, such as:
- Adding CSRF tokens to all forms that perform sensitive actions
- Verifying the origin of requests
- Implementing SameSite cookie attributes
- As a temporary measure, administrators should be cautious about visiting unknown websites while logged into the YzmCMS admin panel.
- Consider implementing additional security controls such as:
- IP-based access restrictions for administrative functions
- Two-factor authentication for administrative accounts
- Regular security audits and vulnerability assessments
