# CVE-2026-92199: Quest Foglight for Databases EncryptionUtil Hardcoded Encyption Key Local Privilege Escalation Vulnerability

Affects Quest Foglight for Databases with no version range given; an attacker needs low-privileged code execution first. Fixed in Foglight 8.3.

- Severity: CVSS 7.8 (High), CNA
- Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Known exploited (CISA KEV): no
- Exposure: Specific setups only
- Fixed in: Foglight 8.3
- Published: 2026-11-03 · Updated: 2026-11-03

CVE-2026-92199 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 7.8 (high) and affects Foglight for Databases; fixed in Foglight 8.3.

## Summary

Quest Foglight for Databases is affected by this vulnerability, which allows a local attacker who already has low-privileged code execution on the system to gain higher privileges, including running code as SYSTEM. The flaw stems from a hard-coded cryptographic key used in the software's encryption utility, which undermines the protection of encrypted data.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Quest Foglight for Databases: 8.2.0

## Description

Quest Foglight for Databases EncryptionUtil Hardcoded Encyption Key Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Quest Foglight for Databases. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the symmetricDecrypt method. The issue results from the use of a hard-coded cryptographic key. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-29967.
