CVE Identifier: CVE-2026-38945

Affected products: RayVentory Scan Engine 12.6 Update 8 and previous versions.

Description

The RayVentory Inventory Agent (rvia) was vulnerable to arbitrary code execution through a malformed find command used in Java executable detection. This vulnerability exploited the application's internal search logic rather than standard PATH manipulation.

Technical Details

Attack Vector: Local
Impact: Arbitrary Code Execution (ACE)
Mechanism: The agent used a find command with improperly terminated search criteria to locate Java installations. Attackers could craft specific directory structures that satisfied the malformed search criteria, causing the agent to execute a malicious binary during the Java detection process.

Severity

Rating: Critical
CVSS Base Score: [Pending]

Remediation

Fixed Version: RayVentory Scan Engine 12.6.3800.131 Update 9 (Released Feb 4, 2026)
