Description

AI Translation Available

An unauthenticated credential disclosure vulnerability in the /goform/ate endpoint of Nexxt Solutions Nebula 300+ firmware through Nebula300+_v12.01.01.37 allows an adjacent attacker to obtain the administrator password in Base64-encoded form via a crafted HTTP request. The recovered credential can be used to authenticate to the device and facilitates further compromise when combined with other weaknesses present in the firmware.
