SB2019042214 - OS Command Injection in Liferay Enterprise Portal

Description

This security bulletin contains information about 1 vulnerability.

1) OS Command Injection (CVE-ID: CVE-2019-11444)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote privileged user to execute arbitrary code.

** DISPUTED ** An issue was discovered in Liferay Portal CE 7.1.2 GA3. An attacker can use Liferay's Groovy script console to execute OS commands. Commands can be executed via a [command].execute() call, as demonstrated by "def cmd =" in the ServerAdminPortlet_script value to group/control_panel/manage. Valid credentials for an application administrator user account are required. NOTE: The developer disputes this as a vulnerability since it is a feature for administrators to run groovy scripts and therefore not a design flaw.

Remediation

Install update from vendor's website.
