Liferay Portal Server tested on 7.3.5 GA6, 7.2.0 GA1 is affected by OS Command Injection.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.03%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Liferay Portal Server tested on 7.3.5 GA6, 7.2.0 GA1 is affected by OS Command Injection. An administrator user can inject Groovy script to execute any OS command on the Liferay Portal Sever. 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.
