Incident Report for cPanel - Services
Identified Update: cPanel Patch Deployment Underway
cPanel has released a patch to address the authentication vulnerability that was identified today. As a security measure, we took initiative and blocked all ports to ensure that your servers are not impacted just like every other server is compromised. Our engineers are currently working on deploying this patch across eligible cPanel services.
Once the patch is successfully applied, we will take the following actions:
Remove the network-level firewall blocks.
cPanel: 2082 / 2083
WHM: 2086 / 2087
Webmail: 2095 / 2096
Web Disk: 2077 / 2078
Re-enable the cPanel web service (cpsrvd).

We appreciate your continued patience as we complete these actions to restore full service. If you have any questions in the meantime, please contact us for assistance.
Update
cPanel has disclosed that the additional cPanel-provided services Webmail and Web Disk are impacted by this vulnerability.
Out of an abundance of caution, and based on cPanel’s current recommendation, we are implementing temporary protective changes on servers hosted on our network.
Temporary changes being implemented:
-Blocking access to ports related to cPanel services:
WHM: 2082 / 2083
cPanel: 2086 / 2087
Webmail: 2096 / 2097
Web Disk: 2077 / 2078
-Temporarily disabling cpsrvd, which is the web wrapper for cPanel web services.As a result, cPanel, WHM, Webmail, Web Disk, and related cPanel services will be inaccessible.
These changes do not impact websites, email delivery, databases, or Apache functionality.
Customers who normally access email through Webmail can still access email by using a mail client (Outlook and Thunderbird etc.).
These temporary restrictions will be reverted as soon as cPanel releases a patch addressing the critical vulnerabilities.

Update
A brief configuration issue in our Ashburn (NTT) data center caused an un-intended disruption to outbound network traffic. Customers with servers in this location may have experienced intermittent connectivity or downtime lasting approximately 10 minutes. Our team quickly identified and corrected the issue. All services have since been restored and are functioning normally.
We continue to restrict access to cPanel/WHM interfaces on ports 2082, 2083, 2086, and 2087 across our data centers until a patch is released by cPanel.
If you need assistance with any cPanel/WHM items please reach out to support through live chat or a ticket.
We will provide additional updates to this status page as more information is made available.
Investigating
We are actively responding to a critical vulnerability affecting all versions of cPanel & WHM. This vulnerability impacts the authentication process and could allow unauthorized access if left unmitigated.
More information from cPanel is available here:
https://support.cpanel.net/hc/en-us/articles/40073787579671-Critical-Vulnerability-with-cPanel-WHM-Login-Authentication
Our team is working alongside implementing proactive safeguards to protect environments.
As an immediate precaution, we have temporarily restricted access to cPanel/WHM interfaces on the following ports 2082, 2083, 2086, and 2087. Restricted access will remain in place until a patch is developed and deployed. This action is being taken to prevent potential unauthorized access while a permanent fix is finalized.
Impact:
-Restricting access to cPanel/WHM Ports via a network firewall block. During this time customers will not be able to login to either WHM or cPanel.
-No impact to hosted websites, applications, email or services.
We are closely monitoring the official patch release from cPanel and will deploy it as quickly as possible. Once mitigations are no longer required, normal access will be restored.
Until a patch is released by cPanel customers will need to reach out to support via live chat or ticket for assistance.
No additional action is required at this time. We will provide additional updates to this announcement page as more information is made available.
This incident affects: CPanel.
