A vulnerability in the web-based UI of Cisco Secure Access Control Server could allow an authenticated, remote attacker to gain read access to certain information in an affected system. The vulnerability is due to improper handling of XML External Entities (XXEs) when parsing an XML file. An attacker could exploit this vulnerability by convincing the administrator of an affected system to import a crafted XML file.
Weakness
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
