URGENT — Security Advisory
A privilege-escalation vulnerability has been identified in the LiteSpeed User-End cPanel Plugin. This issue is separate from the one patched last month, and is being actively exploited in the wild. A CVE is forthcoming.
Affected: LiteSpeed User-End cPanel Plugin prior to 2.4.8
Not affected: LiteSpeed WHM Plugin (the parent plugin)
Status: Fix available
ACTION REQUIRED (immediately)
We strongly recommend you urgently upgrade to:
LiteSpeed WHM Plugin v5.3.2.1 (bundled w/ cPanel plugin v2.4.8).
Alternative: Uninstall the Vulnerable Plugin
If you cannot upgrade immediately, please run the following command as root to remove the plugin:
Bash
/usr/local/lsws/admin/misc/lscmctl cpanelplugin --uninstall
This will remove the vulnerable User-End plugin from existing accounts and prevent it from being installed on new accounts.
