Descriptions

Bitmask Riseup VPN 0.21.6 contains a local privilege escalation flaw due to improper access controls. When the software is installed with a non-default installation directory off of the system root, the installer fails to properly set ACLs. This allows lower privileged users to replace the VPN executable with a malicious one. When a higher privileged user such as an Administrator launches that executable, it is possible for the lower privileged user to escalate to Administrator privileges.

Bitmask Riseup VPN versión 0.21.6, contiene un fallo de escalada de privilegios local debido a controles de acceso inapropiados. Cuando el software es instalado con un directorio de instalación no predeterminado fuera del root del sistema, el instalador no establece correctamente las ACL. Esto permite a usuarios con menos privilegios sustituir el ejecutable de la VPN por uno malicioso. Cuando un usuario con más privilegios, como un administrador, lanza ese ejecutable, es posible que el usuario con menos privilegios escale a privilegios de administrador.
