Supposedly patched router backdoor was simply hidden

2014/04/22

Help Net Security - (International) A security researcher who discovered a backdoor vulnerability in several popular home routers found that the firmware update issued by manufacturer Sercomm does not close the vulnerability but instead hides the backdoor. The backdoor can then be opened after sending a specific network packet to the router from the local area network (LAN) or the Internet service provider (ISP), allowing attackers reset the device's configuration, username, and password to default settings.
