CVE-2026-6482

Full vulnerability record from the local CVENow database.

Description

The Rapid7 Insight Agent (versions > 4.1.0.2) is vulnerable to a local privilege escalation attack that allows users to gain SYSTEM level control of a Windows host. Upon startup the agent service attempts to load an OpenSSL configuration file from a non-existent directory that is writable by standard users. By planting a crafted openssl.cnf file an attacker can trick the high-privilege service into executing arbitrary commands. This effectively permits an unprivileged user to bypass security controls and achieve a full host compromise under the agent’s SYSTEM level access.

      "value": "El Agente Rapid7 Insight (versiones mayor que 4.1.0.2) es vulnerable a un ataque de escalada de privilegios local que permite a los usuarios obtener control a nivel de SYSTEM de un host Windows. Al iniciar, el servicio del agente intenta cargar un archivo de configuración de OpenSSL desde un directorio inexistente que es escribible por usuarios estándar. Al colocar un archivo openssl.cnf manipulado, un atacante puede engañar al servicio de altos privilegios para que ejecute comandos arbitrarios. Esto permite efectivamente a un usuario sin privilegios eludir los controles de seguridad y lograr un compromiso completo del host bajo el acceso a nivel de SYSTEM del agente."
