Ruin Your Friday With Critical cPanel and WHM Bugs - PC Perspective

A report says critical bugs in cPanel and WHM have pushed some hosting providers to block admin ports 2083 and 2087 until patches are in place.

Evidence suggests attacks may have been happening since February, raising concern that the flaws are already being actively exploited.

The issues affect widely exposed cPanel/WHM installations and create immediate risk for hosting providers and sysadmins.
