Cisco Secure Access Control System contains a vulnerability that could allow an authenticated, remote attacker to bypass security restrictions and gain access to sensitive information. Updates are available.
A vulnerability in the Remote Method Invocation (RMI) interface of the Cisco Secure Access Control System (ACS) could allow an authenticated, remote attacker to read arbitrary files on the Cisco Secure ACS server.
The vulnerability is due to insufficient authorization enforcement. An attacker could exploit this vulnerability by accessing the Cisco Secure ACS via the RMI interface. An exploit could allow the attacker to read arbitrary files located on the Cisco Secure ACS.
Cisco has confirmed the vulnerability in a security notice and released software updates.
At the time this alert was first published, Cisco ACS versions 5.4(.0.46.3) and prior were vulnerable. Later releases of Cisco ACS may also be vulnerable.
To exploit this vulnerability, an attacker must authenticate to a targeted device. This access requirement reduces the likelihood of a successful exploit.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
Cisco has released a security notice at the following link: CVE-2014-0667
