Version Summary: Cisco Identity Services Engine guest portal contains a
vulnerability that could allow an unauthenticated, remote attacker to gain
unauthorized access. Updates are not available.
Description
A vulnerability in the Cisco Identity Services Engine (ISE) guest portal could
allow an unauthenticated, remote attacker to view a customized page on the
guest portal.
The vulnerability is due to lack of access control for the uploaded HTML
files. An attacker could exploit this vulnerability by crafting an HTTP
request that points to the filename of the customized page.
Cisco has confirmed the vulnerability; however, software updates are not
available.
Warning Indicators
At the time this alert was first published, Cisco Identity Services Engine
(ISE) 3300 series version 1.2(0.899) was vulnerable. Other releases of Cisco
ISE may also be affected.
IntelliShield Analysis
To exploit this vulnerability, the attacker must send a crafted HTTP request
to the filename of the customized page on the guest portal. The Cisco ISE
guest portal is configured to use customized uploaded HTML files, making an
exploit easier to accomplish. Environments that restrict access from untrusted
sources could make successful exploitation more difficult.
Cisco indicates through the CVSS score that functional exploit code exists;
however, the code is not known to be publicly available.
Vendor Announcements
Cisco has released bug ID CSCuo78045 for registered users, which contains
additional details and an up-to-date list of affected product versions.
Impact
An unauthenticated, remote attacker could exploit the vulnerability to access
the affected software and view any customized HTML page on the guest portal
without authentication.
Technical Information
The vulnerability is due to lack of access control for the uploaded HTML
files.
An unauthenticated, remote attacker could exploit the vulnerability by
crafting an HTTP request that points to the filename of the customized page.
An exploit could allow the attacker to view information on the page.
Safeguards
Administrators are advised to monitor affected systems.
Administrators are advised to not place confidential content in the customized
pages.
Administrators may consider using IP-based access control lists (ACLs) to
allow only trusted systems to access the affected systems.
Patches/Software
