Descriptions

Cloudflare WARP for Windows allows privilege escalation due to an unquoted service path. A malicious user or process running with non-administrative privileges can become an administrator by abusing the unquoted service path issue. Since version 1.2.2695.1, the vulnerability was fixed by adding quotes around the service's binary path. This issue affects Cloudflare WARP for Windows, versions prior to 1.2.2695.1.

Cloudflare WARP para Windows permite un escalada de privilegios debido a una ruta de servicio sin comillas. Un usuario o proceso malicioso que se ejecuta con privilegios no administrativos puede convertirse en administrador si abusa del problema de la ruta de servicio sin comillas. A partir la versión 1.2.2695.1, la vulnerabilidad se solucionó agregando comillas alrededor de la ruta binaria del servicio. Este problema afecta a Cloudflare WARP para Windows, versiones anteriores a 1.2.2695.1
