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 paFnUploadFileAndCreateInfo script. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-29038.","summary":"Teams running a Quest Foglight for Databases management server on a version before 8.3 are exposed. An attacker needs a valid Foglight login; they can then abuse an unvalidated file path in the paFnUploadFileAndCreateInfo script to run code as SYSTEM.
