ZDI-26-855: Quest Foglight for Databases install License Directory Traversal Remote Code Execution Vulnerability
Summary: The Zero Day Initiative published ZDI-26-855, a directory traversal flaw in the installLicense script of Quest Foglight for Databases that lets an authenticated remote attacker execute arbitrary code as SYSTEM. The flaw stems from missing validation of a user-supplied path before it is used in file operations, and it is fixed in Foglight 8.3.
Key Takeaway: Exploitation requires authentication, but success hands the attacker code execution at SYSTEM level on a database monitoring server - the kind of host with broad visibility and credentials across the estate.
