Descriptions

Rapid7 Insight Agent, versions 3.0.1 to 3.1.2.34, suffer from a local privilege escalation due to an uncontrolled DLL search path. Specifically, when Insight Agent versions 3.0.1 to 3.1.2.34 start, 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 3.1.2.35. This vulnerability is a regression of CVE-2019-5629.

Rapid7 Insight Agent, versiones 3.0.1 a 3.1.2.34, sufre una escalada de privilegios local debido a una ruta de búsqueda de DLL no controlada. En concreto, cuando se inician las versiones 3.0.1 a 3.1.2.34 del Agente Insight, el intérprete de Python intenta cargar python3.dll en "C:\DLLs\python3.dll", que normalmente es escribible por los usuarios autenticados localmente. Debido a esto, un usuario local malicioso podría usar las condiciones de inicio del Agente Insight para elevarse a privilegios SYSTEM. Este problema ha sido corregido en Rapid7 Insight Agent versión 3.1.2.35. Esta vulnerabilidad es una regresión de CVE-2019-5629
