Description

An issue was discovered in SMA Solar Technology products. When signed into Sunny Explorer with a wrong password, it is possible to create a debug report, disclosing information regarding the application and allowing the attacker to create and save a .txt file with contents to his liking. An attacker may use this for information disclosure, or to write a file to normally unavailable locations on the local system.
