Exploitation Conditions

Exploitation requires that Quest Foglight for Databases be installed (the flaw is in the product installer, which assigns incorrect permissions to a folder it creates) AND that the attacker already possess the ability to run low-privileged code on that same host (AV:L, PR:L). These two prerequisites are the primary limiting factors: there is no remote, unauthenticated, or network path, and user interaction is not required (UI:N). The exact folder, the writable permission condition, and how the product consumes the planted content are not described in the available sources, so whether a non-default configuration is needed cannot be confirmed.

Impact

This is a locally-exploitable privilege escalation (CVSS:3.0 AV:L/AC:L/PR:L/UI:N) scoring 7.8, driven entirely by high confidentiality, integrity, and availability impact (C:H/I:H/A:H) achieved by escalating to SYSTEM - not by ease of initial access. The vector confirms the attacker must already hold low-privileged code execution on the host (AV:L, PR:L), so this is a second-stage escalation primitive rather than a remote entry point. Signal completeness is limited: no EPSS score, no KEV listing, and no confirmed public exploit were provided, so widespread opportunistic exploitation cannot be inferred. The vuln.today decision label is 'this_week,' indicating meaningful but non-emergency priority, consistent with a local-only, authentication-requiring flaw. The lone reference is the ZDI advisory (ZDI-26-865, formerly ZDI-CAN-31118); this is a coordinated-disclosure advisory, not verified working exploit code. Net: a genuine privilege-escalation risk on hosts where Foglight is installed and where attackers can already run low-privileged code, but absent EPSS/KEV/POC evidence it is a patch-this-week issue rather than a mass-exploitation emergency.

Exploit ScenarioDerived

An attacker who has already gained low-privileged code execution on a host running Quest Foglight for Databases abuses incorrect permissions on a product folder created by the installer - for example, replacing or planting a file that the product later executes in a SYSTEM context. This yields arbitrary code execution as SYSTEM, fully compromising the host. No public exploit was identified at time of analysis, and the local attack vector requires prior foothold on the machine.

AnalysisAIv1 – Nov 04, 2026

Local privilege escalation in Quest Foglight for Databases lets an attacker who already has low-privileged code execution on the same host obtain SYSTEM privileges by abusing incorrect folder permissions created by the product installer. The issue is scored CVSS 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and requires local access plus existing low-privileged code execution; it is not remotely reachable and needs no user interaction. No public exploit code was identified at time of analysis.

RemediationAI

No vendor-released patch or fixed version is identified in the available data; consult ZDI-26-865 (https://www.zerodayinitiative.com/advisories/ZDI-26-865/) and Quest's advisory for update guidance. As a compensating control, review and correct the ACLs on the installer-created folder or folders used by Foglight for Databases so that non-administrative local users cannot write to them; this may affect product operation if a service account requires write access, so test in a staged environment. Because exploitation requires prior low-privileged code execution on the host, restricting local logon and code-execution rights on Foglight servers to trusted administrators reduces exposure, at the cost of tighter operational access.

Affected ProductsAI

Quest Foglight for Databases installations are affected, with the product installer identified as the vulnerable component. The provided intelligence does not specify a version range or CPE string. The reporting source is Trend Micro Zero Day Initiative advisory ZDI-26-865 (https://www.zerodayinitiative.com/advisories/ZDI-26-865/), which tracks the issue as ZDI-CAN-31118.

Technical ContextAI · show details

The root cause is CWE-732 (Incorrect Permission Assignment for Critical Resource) in the Quest Foglight for Databases installer. The installer assigns incorrect permissions to a folder used by the product, and the described impact is that a low-privileged local user can abuse those permissions to escalate to SYSTEM and execute arbitrary code. The available sources do not identify the exact folder, the precise writable permission condition, or how the product consumes content placed in that folder, so whether a non-default configuration is required cannot be confirmed. The CVSS vector AV:L/AC:L/PR:L/UI:N confirms a local attack requiring prior low-privileged code execution, with high confidentiality, integrity, and availability impact.

DescriptionCVE.org

Quest Foglight for Databases Incorrect Permission Assignment 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 product installer. The issue results from incorrect permissions on a folder used by the product. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-31118.

Executive ViewAI

Why It Matters

Quest Foglight for Databases contains a high-severity local privilege escalation flaw that allows a low-privileged attacker with existing code execution on the same host to obtain SYSTEM rights. This could enable broader compromise of database monitoring infrastructure and sensitive data, affecting IT security and database administration teams. Leadership should prioritize remediation due to the potential for lateral movement and data breach.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: restrict local access, enforce least privilege, monitor for suspicious process creation, and correct folder permissions per vendor guidance.

Attack Technique

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
