Version Summary:Cisco Identity Services Engine Software contains a vulnerability that could allow an authenticated, remote attacker to conduct SQL injection attacks. Updates are not available.
 
 
Description
A vulnerability in the web framework of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to impact the integrity and availability of the affected system by executing arbitrary SQL queries.

The vulnerability is due to a failure to validate user-supplied input used in SQL queries. An attacker could exploit this vulnerability by sending crafted URLs including SQL statements. An exploit could allow the attacker to modify or delete entries in some database tables, affecting the integrity and availability of some functions.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.
 
Warning Indicators
At the time this alert was first published, Cisco ISE versions 1.2 and prior were vulnerable. Later releases of Cisco ISE Software may also be vulnerable.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker must be able to authenticate to a targeted device to submit malicious SQL statements. In addition, the attacker may need access to trusted, internal networks in which the targeted device may reside. These access requirements could reduce the likelihood of a successful exploit.
 
Vendor Announcements
Cisco has released a security notice at the following link: CVE-2013-5525

Customers are advised to consult Cisco bug ID CSCug90502 for a complete list of affected product versions.
 
Impact
An authenticated, remote attacker could exploit this vulnerability to execute arbitrary SQL queries on the back-end database. Successful exploitation could allow the attacker to modify the underlying database by injecting arbitrary SQL statements in an entry field. This could affect the integrity and availability of some functions, which could be used to conduct further attacks.
 
Technical Information
The vulnerability is due to insufficient validation of user-supplied input used in SQL queries.

An authenticated, remote attacker could exploit this vulnerability by sending crafted URLs including by SQL statements. A successful exploit could allow the attacker to modify or delete entries in some database tables, affecting the integrity and availability of some functions.
 
Safeguards
