CVE-2026-42218

xrdp is an open source RDP server. Versions 0.10.6 and prior contain a timing side-channel vulnerability in the login interface. Due to a discrepancy in response processing times, a remote attacker can infer the existence of a username on the system, leading to unauthorized information disclosure via username enumeration. This issue has been fixed in version 0.10.6.1.

Summary		(es) xrdp es un servidor RDP de código abierto. Las versiones 0.10.6 y anteriores contienen una vulnerabilidad de canal lateral de temporización en la interfaz de inicio de sesión. Debido a una discrepancia en los tiempos de procesamiento de respuesta, un atacante remoto puede inferir la existencia de un nombre de usuario en el sistema, lo que lleva a una revelación de información no autorizada a través de la enumeración de nombres de usuario. Este problema ha sido solucionado en la versión 0.10.6.1.
