CVE-2019-5629 Information

Description

Rapid7 Insight Agent version 2.6.3 and prior suffers from a local privilege escalation due to an uncontrolled DLL search path. Specifically when Insight Agent 2.6.3 and prior starts the Python interpreter attempts to load python3.dll at \C:\DLLs\python3.dll\ which normally is writable by locally authenticated users. Because of this a malicious local user could use Insight Agent’s startup conditions to elevate to SYSTEM privileges. This issue was fixed in Rapid7 Insight Agent 2.6.4.
