Cisco ISE contains a vulnerability that could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive information. Updates are available.
A vulnerability in the implementation of the authentication code that is used to validate requests to download a product support bundle could allow an unauthenticated, remote attacker to download a full product support bundle.
The vulnerability is due to an error in the logic that is used to validate support bundle access requests. An attacker could exploit this vulnerability by sending a crafted request to the vulnerable system. An exploit could allow an attacker to obtain a full copy of the product configuration or other sensitive information including administrative credentials.
Cisco confirmed the vulnerability in a security advisory and released software updates.
Cisco ISE versions prior to 1.1.1 are affected.
A successful exploit could allow an attacker to gain access to information in support packages stored on the targeted system. The file contents may include authentication credentials that could allow the attacker to conduct further exploits against the targeted system or other related systems.
An unauthenticated, remote attacker could gain unauthorized access to files on a targeted system.
The vulnerability is due to improper authentication checks when accessing files on the affected system.
An unauthenticated, remote attacker could exploit the vulnerability by sending a malicious request to the targeted system. Improper processing by the system could allow the attacker to download files from the system without authorization, possibly resulting in the disclosure of sensitive information.
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 monitor affected systems.
