Summary
Quest Foglight for Databases is affected by this vulnerability, which allows an unauthenticated remote attacker to run arbitrary code with SYSTEM privileges on the server. The flaw stems from unsafe handling of untrusted data during deserialization in the software's RMI service configuration.
Read the original description
Quest Foglight for Databases baseRmiServiceExporter Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Quest Foglight for Databases. Authentication is not required to exploit this vulnerability. The specific flaw exists within the configuration of the baseRmiServiceExporter bean. The issue results from the lack of proper validation of user-supplied data prior to deserializing it. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-29170.
What to do
Upgrade to a fixed version: 8.3.

Questions about CVE-2026-92190
Is CVE-2026-92190 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The flaw is a deserialization of untrusted data in the configuration of the baseRmiServiceExporter bean. The advisory says an attacker can use it to execute code in the context of SYSTEM.Source: zerodayinitiative.com
Which versions are affected by CVE-2026-92190?
Foglight for Databases: version 8.2.0.Source: cve.now feed data
Am I affected, and how do I check?
The advisory names Quest Foglight for Databases and the baseRmiServiceExporter bean configuration, but it does not list affected version ranges. To check an installation, look at the installed Foglight for Databases version and whether its configuration includes the baseRmiServiceExporter bean.Source: zerodayinitiative.com
How do I fix CVE-2026-92190?
Upgrade to Foglight 8.3, the version the advisory names as fixed. The facts list no workaround.Source: zerodayinitiative.com
