What is CVE-2016-15056?

The Ubee EVW3226 cable modem/router firmware versions up to and including 1.0.20 exhibit a serious security flaw where configuration backup files are stored in the web root post-generation. These files can be accessed without authentication until the device is rebooted. A remote attacker on the same local network can exploit this issue by directly requesting the 'Configuration_file.cfg', leading to the exposure of sensitive data, including the plaintext admin password, which may result in complete device compromise.
