Arbitrary File Download in Cisco Identity Services Engine Web Management Interface

Successful exploitation allows an authenticated remote attacker to access arbitrary files from the filesystem of the affected Cisco ISE device. This can expose sensitive information stored locally, including configuration data, credentials, keys, tokens, logs, or other operational artifacts, depending on file permissions and product configuration. The resulting disclosure may facilitate further compromise of the appliance or connected environments.

If immediate patching is not possible, reduce exposure of the Cisco ISE web-based management interface to only trusted administrative networks, restrict remote administrative access with network segmentation and access controls, and minimize the number of accounts permitted to authenticate to the interface. Monitor administrative access and HTTP activity for anomalous file retrieval behavior. No specific complete workaround is currently available from the provided information beyond applying vendor fixes and limiting access.

Apply the Cisco security updates for affected Cisco Identity Services Engine releases as provided by Cisco. Because the issue is rooted in server-side input validation in the web management interface, remediation requires upgrading to a fixed software version supplied by the vendor.
