CVE-2026-23760

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-23760
SmarterTools SmarterMail versions prior to build 9511 contain an authentication bypass vulnerability in the password reset API. The force-reset-password endpoint permits anonymous requests and fails to verify the existing password or a reset token when resetting system administrator accounts. An unauthenticated attacker can supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance. NOTE: SmarterMail system administrator privileges grant the ability to execute operating system commands via built-in management functionality, effectively providing administrative (SYSTEM or root) access on the underlying host.

Summary
  • (es) Las versiones de SmarterTools SmarterMail anteriores a la compilación 9511 contienen una vulnerabilidad de omisión de autenticación en la API de restablecimiento de contraseña. El endpoint force-reset-password permite solicitudes anónimas y no verifica la contraseña existente o un token de restablecimiento al restablecer cuentas de administrador del sistema. Un atacante no autenticado puede proporcionar un nombre de usuario de administrador objetivo y una nueva contraseña para restablecer la cuenta, lo que resulta en un compromiso de administración total de la instancia de SmarterMail. NOTA: Los privilegios de administrador del sistema de SmarterMail otorgan la capacidad de ejecutar comandos del sistema operativo a través de la funcionalidad de gestión incorporada, proporcionando efectivamente acceso de administrador (SYSTEM o root) en el host subyacente.
