Overview: The Aruba Mobility Controller?s management interfaces are susceptible to a heap based buffer overflow vulnerability, Description: Both the command line based and the web based management interface of the Aruba Mobility Controller are vulnerable to a heap based buffer overflow when overly long strings are passed as credentials. This can potentially lead to remote code execution, resulting in a system compromise. Impact: The overflow will in any case result in memory corruption that crashes the management interface?s process, leading to a Denial of Service (DoS) condition of the remote management capabilities. A carefully crafted overflow may result in code execution, allowing an attacker to fully control the device. Solution: Aruba Networks has made patched firmware available to their customers, who should be able to retrieve it through Aruba's support site https://support.arubanetworks.com. As a workaround, restrict access to the administrative interfaces or disable them, reverting to console-only administration. Credit: Bugs found by Jan Mnther and Maxim Salomon of n.runs AG.
