Cisco Prime Infrastructure Log File Download Authorization Bypass

Executive Summary

This vulnerability exists in the log file download functionality of Cisco Prime Infrastructure. It allows an authenticated remote attacker to download arbitrary log files from the server due to insufficient authorization checks on the download service API.

An attacker can exploit this by submitting a specially crafted URL request to the affected device. However, the attacker must have valid credentials to access the web-based management interface to carry out the exploit.

If successful, the attacker could access sensitive log files that they are not authorized to view.
