Base - 5.5

Cisco Bug IDs:

CSCuw81497

CVE-2016-1358

CWE-119

Summary

A vulnerability in the web-based user interface of Cisco Prime Infrastructure
could allow an authenticated, remote attacker to have read access to 
confidential information stored in the affected system. In addition, the 
attacker could cause a partial denial of service (DoS) condition due to 
manipulation of system resources.

The vulnerability is due to improper handling of XML External Entity (XXE) 
when parsing an XML file. An attacker could exploit this vulnerability by 
convincing the authenticated administrator of the affected system to import a
crafted XML file. An exploit could allow the attacker to view confidential 
files or cause a DoS condition.

Cisco has not released software updates that address this vulnerability. 
Workarounds that mitigate this vulnerability are not available.
