Asus has issued patches for a series of USB enabled routers which were vulnerable to remote compromise.
The bugs affected users of eight router models with the AiCloud mobile app service activated.
Researcher Kyle Lovatt dropped the vulnerabilities ahead of the patches on the Full Disclosure mailing list after claiming Asus did not adequately respond to warn customers and patch the flaws.
He said "no serious attempt" was made to warn customers after "multiple requests from several different security professionals".
"Nor has ASUS posted a disclosure of these serious issues to new potential customers on their AiCloud web adverts since they still advertise the product as an add-on with these routers, as a safe and bug free home cloud solution," Lovatt said.
"Almost all models will disclose a clear text creational file, making any MD5 hashing on the /etc/shadow file meaningless."
The patches were available on the Asus website.
