Version Summary: Cisco Secure Access Control Server contains a vulnerability
that could allow an unauthenticated, remote attacker to conduct cross-site
request forgery attacks. Updates are available.
Description
A vulnerability in the Dashboard page in the monitoring and report section of
Cisco Secure Access Control Server could allow an unauthenticated, remote
attacker to perform a cross-site request forgery (CSRF) attack.
The vulnerability is due to the improper generation and validation of the CSRF
token by an affected system. An unauthenticated, remote attacker could exploit
this vulnerability by persuading a user of the affected system to follow a
malicious link or visit an attacker-controlled website. A successful exploit
could allow the attacker to perform unauthorized actions on the targeted
system on behalf of the user.
Cisco has confirmed the vulnerability and released software updates.
Warning Indicators
Cisco Secure Access Control Server Solution Engine prior to version
5.5(0.46.5) are affected.
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a
user to a malicious site and use misleading language or instructions to
convince the user to follow the link.
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 CSCuj62924 for registered users that contains
additional details and an up-to-date list of affected product versions.
Impact
An unauthenticated, remote attacker could exploit this vulnerability to take
unauthorized actions on behalf of a targeted user. Successful exploitation
could allow the attacker to conduct further attacks.
Technical Information
The vulnerability is due to the improper generation and validation of the CSRF
token by an affected system.
An unauthenticated, remote attacker could exploit this vulnerability by
convincing a user of the affected system to follow a malicious link or visit
an attacker-controlled website. A successful exploit could allow the attacker
to perform unauthorized actions on the targeted system on behalf of the user.
Safeguards
Administrators are advised to apply the appropriate updates.
Users should verify that unsolicited links are safe to follow.
