Critical TLStorm 2.0 Bugs Affect Widely-Used Aruba and Avaya Network Switches
May 03, 2022
Cybersecurity researchers have detailed as many as five severe security flaws in the implementation of TLS protocol in several models of Aruba and Avaya network switches that could be abused to gain remote access to enterprise networks and steal valuable information. The findings follow the March disclosure of TLStorm , a set of three critical flaws in APC Smart-UPS devices that could permit an attacker to take over control and, worse, physically damage the appliances. IoT security firm Armis, which uncovered the shortcomings, noted that the design flaws can be traced back to a common source: a misuse of NanoSSL , a standards-based SSL developer suite from Mocana, a DigiCert subsidiary. The new set of flaws, dubbed TLStorm 2.0 , renders Aruba and Avaya network switches vulnerable to remote code execution vulnerabilities, enabling an adversary to commandeer the devices, move laterally across the network, and exfiltrate sensitive data. Affected devices include Avay...
