description

cPanel & WHM 124-and-later builds are affected by improper handling of NUL bytes. An unauthenticated remote attacker may retrieve calendar and contact data belonging to mail accounts hosted on an affected server.

mitigation

Update cPanel & WHM to the vendor’s fixed release. The supplied evidence does not identify the specific fixed version; restrict unnecessary public access to affected servers until the update is applied.

fixed in 11.138.0.19, 11.136.0.51, 11.134.0.67, 11.110.0.154
