The company has over 1,800 employees and is headquartered in Sunnyvale, California. Aruba's core products are access points (APs), mobility controllers, and network management software through their Airwave Management Platform product." Source: https://en.wikipedia.org/wiki/Aruba_Networks Vulnerability overview/description: ----------------------------------- A browser-trusted certificate (CN: securelogin.arubanetworks.com, signed by GeoTrust) including its private key is embedded in the firmware of several Aruba Networks/Alcatel-Lucent products. The certificate is used for providing user access to a captive portal and web administration via HTTPS as well as EAP connections for WPA2-Enterprise clients. An attacker can use this vulnerability to impersonate a captive portal, web administration or Wi-Fi AP and gain access to sensitive information. The certificate is compromised and should be revoked. Users should be told to install certificates generated by themselves.

We found the certificate and private key in firmware for various Alcatel-Lucent OmniAccess products, potentially other products are affected as well. According to Aruba, "The certificate "securelogin.arubanetworks.com", and its associated private key, is distributed on every controller and in every software release." Vendor contact timeline: ------------------------ 2015-05-21: Contacting vendor through sirt () arubanetworks com, answer regarding affected products 2015-05-28: Update from Aruba, certificate for "securelogin.arubanetworks.com" will not be changed; documentation will be updated to reflect security issues. 2015-06-08: Certificate will not be revoked, announcement available here: http://community.arubanetworks.com/t5/Unified-Wired-Wireless-Access/Certificate-quot-securelogin-arubanetworks-com-quot/td-p/239148 2015-11-25: "House of Keys" research study published regarding re-use of crypto secrets in firmware of multiple vendors (advisory postponed) 2016-09-05: Follow-up on "House of Keys", publication of Aruba advisory Solution: --------- None available. Workaround: ----------- Users should install a custom certificate signed by a trusted CA.
