Version Summary:Additional information that describes the Cisco Network Admission Control Manager SQL Injection Vulnerability is publicly available.
 
 
Description
Cisco NAC Manager contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code and take full control of the vulnerable system.

This vulnerability is due to improper validation of user-supplied requests by the Cisco NAC Manager. An attacker could exploit this vulnerability by injecting Structured Query Language (SQL) commands. An exploit could allow the attacker to execute arbitrary queries and take full control of the affected system.

Cisco has confirmed the vulnerability in a security advisory and has released software updates.
 
Warning Indicators
Cisco NAC Manager versions prior to 4.9.2 and prior to 4.8.3.1 are affected.
 
IntelliShield Analysis
To exploit this vulnerability, an attacker may require access to trusted, internal networks to send crafted requests to the affected software. This access requirement could limit the likelihood of a successful exploit.

Cisco NAC Manager is part of the Cisco NAC Appliance, formerly known as Cisco Clean Access. Software versions 4.1.3 and later are using the name Cisco Network Admission Control (NAC).

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 a security advisory for bug ID CSCub23095 at the following link: cisco-sa-20130417-nac
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary SQL statements on the underlying database. This ability could allow the attacker to completely compromise the system.
 
Technical Information
The vulnerability is in the handling of sortcolumn URL parameters when SQL database queries are constructed. It fails to sanitize the user-supplied input before sending it to the Cisco NAC Manager.

An unauthenticated, remote attacker could exploit this vulnerability by sending crafted SQL queries to carry out unauthorized actions on the database and execute arbitrary code.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Administrators are advised to allow only trusted users to have network access.

Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.

Understanding activity on the network provides information and visibility that can be used to identify potential security incidents. Organizations should log events from devices and review the logged data to provide insight into anomalies or malicious activity. For logging best practices, consult the Cisco Guide to Harden Cisco IOS Devices.

Network traffic should be monitored for security-related network activity. NetFlow identifies security-related network activity. For NetFlow configuration details, consult Introduction to Cisco IOS NetFlow - A Technical Overview.

It is critical to prevent unauthorized direct communication to network devices. Restrict network traffic that is destined for the network infrastructure to protect against reconnaissance and denial of service attacks. For configuration details, consult Protecting Your Core: Infrastructure Protection Access Control Lists.

Administrators are advised to monitor affected systems.
