Problem Explanation:
Understanding the Vulnerability
The vulnerability resides in the LiteSpeed Cache plugin’s role simulation feature. By exploiting flaws in this feature, attackers can simulate the roles of legitimate users, including administrators, without proper authentication. This allows them to create new administrator accounts or gain elevated privileges, leading to potential full-site control.
Affected Versions
The vulnerability affects LiteSpeed Cache versions up to 6.3. All websites using these versions are at risk and should immediately update to version 6.4 or higher.
How Hackers Exploit This Flaw
An unauthenticated attacker can spoof their user ID and register as an administrative-level user, effectively granting them privileges to take over a vulnerable WordPress site.
Fixes and Updates:
The LiteSpeed team has addressed this critical issue in version 6.4. The update strengthens the role simulation process and includes additional security measures to prevent unauthorized privilege escalation.
Precautions:
- Backups: Always have your website backup to avoid losing your website to dangerous hackers.
- Update Immediately: Make sure your website plugins/themes/core versions are updated to the latest.
- Regular Scans: Perform regular security audits on your WordPress site to identify potential vulnerabilities and malware.
- Monitoring User Roles: Regularly check user roles and permissions for any unusual changes.
