CVE ID: CVE-2013-1215
Release Date: 2013 April 24 21:06 UTC (GMT)

Summary
A vulnerability in the Easy VPN feature of Cisco ASA Software running on Cisco
ASA 5505 hardware could allow an authenticated, local attacker to elevate their
privileges on the device running Cisco ASA Software.
The vulnerability is due to a mishandling of privilege levels, which are
temporarily manipulated by the vpnclient command. An attacker could exploit
this vulnerability by executing the vpnclient command, if the privilege of
this command is changed, so the local attacker can execute it.
