This vulnerability allows remote attackers to execute arbitrary code on affected installations of Quest Foglight for Databases. Authentication is required to exploit this vulnerability.\n\nThe specific flaw exists within the installLicense script.

An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
