'If you want to issue a firmware upgrade, that's going to be a lot of data coming in and out of the UPS,' he said. But, he said, abnormal traffic would be obvious to anyone who was looking for it. This is very severe,' he said.Įnterprises often let connected UPS systems slip under the radar for network security, said Hadad, leading to a gap in visibility.

'Usually these devices are connected to mission-critical devices. But attackers could just turn stuff on and off or destroy the UPS,' said Hadad. And that can slowly make devices break or behave in a weird way over time. 'A waveform like a square wave is not something that devices expect to receive from the power socket. The set of vulnerabilities offers attackers different options in how to sabotage their victims. Enterprises with NMC backups could add an additional layer of security by guarding the connection with the UPS with an SSL certificate. Schneider has released patches for affected devices. Older devices, using Schneider's NMC (Network Management Card), are subject to an unsigned malicious firmware update over a local network.Īrmis will present their research at BlackHat Asia. Newer devices supporting the 'SmartConnect' feature have both a TLS buffer overflow or TLS authentication bypass vulnerability in the handshake protocol, the latter of which allows the installation of malicious firmware. Armis has dubbed the trio of vulnerabilities 'TLStorm.'ĭifferent Smart-UPS devices of different ages are subject to different vulnerabilities. The vulnerabilities lie in the TLS implementation used by cloud-connected Smart-UPS and unsigned and unauthenticated firmware. 'We've checked with our clients and we see these devices are used by over 50% of our clients,' said Barak Hadad, head of research at Armis.
