What is CVE-2016-15056?
CVE-2016-15056 is a high-severity vulnerability in Ubee EVW3226, published on 14 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Ubee EVW3226 cable modem/routers firmware versions up to and including 1.0.20 store configuration backup files in the web root after they are generated for download. These backup files remain accessible without authentication until the next reboot. A remote attacker on the local network can request 'Configuration_file.cfg' directly to obtain the backup archive. Because backup files are not encrypted, they expose sensitive information including the plaintext admin password, allowing full compromise of the device.
