CVE-2017-9859

An issue was discovered in SMA Solar Technology products. The inverters make use of a weak hashing algorithm to encrypt the password for REGISTER requests. This hashing algorithm can be cracked relatively easily. An attacker will likely be able to crack the password using offline crackers. This cracked password can then be used to register at the SMA servers. NOTE: the vendor's position is that "we consider the probability of the success of such manipulation to be extremely low." Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected

**EN DISPUTA** Se ha descubierto un problema en productos SMA Solar Technology. Los inversores emplean un algoritmo de hash débil para cifrar la contraseña de peticiones REGISTER. Este algoritmo de hash se puede romper con relativa facilidad. Lo más probable es que un atacante sea capaz de descubrir la contraseña empleando crackers offline. Esta contraseña descubierta podrá emplearse para registrarse en los servidores SMA. NOTA: La posición del fabricante es que "nosotros consideramos que la probabilidad de algún tipo de manipulación exitosa es extremadamente baja." También, únicamente podrían estar potencialmente afectados Sunny Boy TLST-21 y TL-21 y Sunny Tripower TL-10 y TL-30
