CVE-2026-92199 · Severity: high · CVSS 7.8 · Published 2026-11-04

Quest Foglight for Databases is a performance monitoring tool for database environments. This vulnerability allows an attacker with low-level access to the system to escalate privileges to SYSTEM level and execute arbitrary code by exploiting a hardcoded encryption key in the EncryptionUtil component. Successful exploitation would grant an attacker complete control over the monitored database infrastructure and the ability to access sensitive performance and configuration data.

## How to fix

- Fixed in Foglight 8.3

## Technical details

The vulnerability exists in the symmetricDecrypt method of EncryptionUtil, which uses a hardcoded cryptographic key instead of a dynamically generated or externally managed key. An attacker with low-privileged code execution can decrypt sensitive data and leverage the hardcoded key material to escalate privileges to SYSTEM context. This is a local attack vector requiring prior code execution capability on the target system.
