Systems Affected * Alcatel OmniSwitch 7700/7800 switches running Alcatel Operating System (AOS) version 5.1.1 Overview Alcatel has recently discovered a serious vulnerability in AOS version 5.1.1. Exploitation of this vulnerability can lead to full administrative control of the device running AOS. I. Description AOS typically runs on network infrastructure devices, such as the Alcatel OmniSwitch 7000 series switch. According to Alcatel: During an NMAP audit of the AOS 5.1.1 code that runs on the Alcatel OmniSwitch 7700/7800 LAN switches, it was determined a telnet server was listening on TCP port number 6778. This was used during development to access the Wind River Vx-Works operating system. Due to an oversight, this access was not removed prior to product release. Further information about this vulnerability may be found in VU#181721. This issue is also being referenced as CAN-2002-1272: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1272 II. Impact An attacker can gain full access to any device running AOS version 5.1.1, which can result in, but is not limited to, unauthorized access, unauthorized monitoring, information leakage, or denial of service. III. Solution Upgrade to AOS 5.1.1.R02 or AOS 5.1.1.R03 Contact Alcatel's customer support for the updated AOS. Workarounds Block access to port 6778/TCP at your network perimeter. Appendix A. - Vendor Information VU#181721 was written by Alcatel. As new vendor information is reported to the CERT/CC, we will update VU#181721 and note the changes in our revision history.
