John Munther and Maxim Salomon have reported two vulnerabilities in Aruba Mobility Controller, which can be exploited by malicious people to bypass certain security restrictions, cause a DoS (Denial of Service), or potentially compromise a vulnerable system.

1) A boundary error within the management interface can be exploited to cause a heap-based buffer overflow by sending overly long strings as credentials.

Successful exploitation crashes the management interface process and may allow arbitrary code execution.

2) An error in the guest account authentication process within the Captive Portal can be exploited to e.g. gain access to administrative sections without specifying a password.

The vulnerabilities are reported in all Aruba Networks Mobility Controller devices with firmware versions 2.0 or greater.

Solution
Update to the latest patched firmware version.
