Descriptions

An issue was discovered on Linksys WRT1900ACS 1.0.3.187766 devices. A lack of encryption in how the user login cookie (admin-auth) is stored on a victim's computer results in the admin password being discoverable by a local attacker, and usable to gain administrative access to the victim's router. The admin password is stored in base64 cleartext in an "admin-auth" cookie. An attacker sniffing the network at the time of login could acquire the router's admin password. Alternatively, gaining physical access to the victim's computer soon after an administrative login could result in compromise.

Fue encontrado un problema en los dispositivos Linksys WRT1900ACS versión 1.0.3.187766. La falta de cifrado en la forma en que la cookie de inicio de sesión del usuario (admin-auth) es almacenada en la computadora de la víctima hace que un atacante local pueda descubrir la contraseña del administrador y la pueda usar para obtener acceso administrativo al enrutador de la víctima. La contraseña de administrador es almacenada en texto sin cifrar base64 en una cookie "admin-auth". Un atacante que espía la red en el momento de iniciar sesión podría adquirir la contraseña de administrador del enrutador. Alternativamente, obtener acceso físico a la computadora de la víctima poco después de un inicio de sesión administrativo podría resultar en un peligro.
