Cisco Prime Data Center Network Manager contains a vulnerability that could allow an unauthenticated, remote attacker to gain root access to sensitive information. Updates are available.
The Cisco Prime Data Center Network Manager (DCNM) is affected by a vulnerability that could allow an unauthenticated remote attacker to access arbitrary text files on the underlying operating system with the privilege of root using an XML External Entity Injection attack.
Cisco has confirmed the vulnerability in a security advisory and has released software updates.
Cisco Prime DCNM versions prior to 6.2(3) are affected.
To exploit this vulnerability, an attacker must conduct an XML external entity injection attack on the targeted device. In a typical enterprise environment, these devices would reside on trusted, internal networks behind firewalls and other security devices. These access restrictions limit the likelihood of a successful exploit.
An unauthenticated, remote attacker could exploit this vulnerability to access arbitrary files on the underlying database with root privileges. 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 conducting an XML external entity injection attack against a targeted device. If processing the incoming requests is successful, XML external entity references and injected tags could allow the attacker to access sensitive information with root privileges. The attacker could use the root privileges to access arbitrary text files to conduct further attacks.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Administrators are advised to allow only privileged users to access administration or management systems.
Administrators are advised to monitor affected systems.
