What is CVE-2017-9861?

A security issue has been found in SMA Solar Technology products due to improper implementation of SIP authentication, which could lead to various types of attacks. Attackers within the LAN can exploit this vulnerability to potentially crash devices, disrupt communication with SMA servers, and capture sensitive information from unencrypted SIP communications. This may allow the extraction of critical data such as passwords. Notably, the vendor suggests that encryption is unnecessary on isolated networks, which raises concerns about security practices.
