Cisco Connected Grid Network Management System contains a vulnerability that could allow an unauthenticated, remote attacker to conduct SQL injection attacks. Updates are available.
A vulnerability in device management of the Cisco Connected Grid Network Management System (CG-NMS) could allow an unauthenticated, remote attacker to modify data in the CG-NMS database by using SQL injection.
The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by including SQL statements in an entry field.
Cisco has confirmed the vulnerability in a security notice and software updates are available.
At the time this alert was first published, Cisco CG-NMS versions 1.0(42) and prior were vulnerable. Later versions of Cisco CG-NMS may also be affected.
To exploit the vulnerability, an attacker would need access to trusted, internal networks to send the crafted queries to the targeted system. This access requirement may reduce the likelihood of a successful attack.
Customers are advised to review the bug reports in the vendor announcements section for a current list of affected versions.
An unauthenticated, remote attacker could exploit this vulnerability to conduct SQL injection attacks on a targeted system and access or modify records on the underlying database. Successful exploitation could be used to conduct further attacks.
The vulnerability is due to insufficient validation of user-supplied input processed by the affected software.
An unauthenticated, remote attacker could exploit this vulnerability by sending crafted SQL queries to a targeted system. When processed, the queries could allow the attacker to perform unauthorized actions on the system, such as modifying sensitive information on the underlying database.
Administrators are advised to apply the appropriate updates.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators are advised to allow only privileged users to access administration or management systems.
Administrators are advised to monitor affected systems.
