Port: Not available

CVE: CVE-2015-4189

Version Summary: Cisco Data Center Analytics Framework contains a 
vulnerability that could allow an unauthenticated, remote attacker to conduct
cross-site request forgery attacks. Updates are not available.

Description

A vulnerability in the Data Center Analytics Framework (DCAF) application 
could allow an unauthenticated, remote attacker to execute unwanted actions.

The vulnerability is due to insufficient cross-site request forgery (CSRF) 
protection. An attacker could exploit this vulnerability by tricking the user
of a web application into executing an adverse action.

Cisco has confirmed the vulnerability; however, software updates are not 
available.

Warning Indicators

At the time this alert was first published, Cisco DCAF release 1.4 was 
vulnerable. Later releases of Cisco DCAF may also be vulnerable.

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 
persuade the user to follow the provided 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 CSCun26807 for registered users, which 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. A successful exploit could
allow the attacker to conduct further attacks.

Technical Information

The vulnerability is due to insufficient validation of user-supplied input by
the affected software.

An attacker could exploit this vulnerability by convincing a user to follow a
malicious link. A successful exploit could allow the attacker to submit 
arbitrary requests to the affected device via the web browser with the 
privileges of the user, which could be leveraged to conduct further attacks.

Safeguards

Administrators are advised to contact the vendor regarding future updates and
releases.

Users should verify that unsolicited links are safe to follow.

For additional information about cross-site request forgery attacks and 
potential mitigation methods, see the Cisco Applied Mitigation Bulletin 
Understanding Cross-Site Request Forgery Threat Vectors.

Administrators are advised to monitor affected systems.

Patches/Software

Software updates are not available.
