A vulnerability in the licensing features of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker with administrative privileges to gain access to sensitive information.
This vulnerability is due to improper parsing of XML that is processed by the web-based management interface of Cisco ISE and Cisco ISE-PIC. An attacker could exploit this vulnerability by uploading a malicious file to the application. A successful exploit could allow the attacker to read arbitrary files from the underlying operating system that could include sensitive data that should otherwise be inaccessible even to administrators. To exploit this vulnerability, the attacker must have valid administrative credentials.
AnalysisAI
Cisco ISE and ISE-PIC suffer from improper XML parsing in their web management interfaces that enables authenticated administrators to extract arbitrary files from the underlying operating system, potentially exposing sensitive data beyond normal access controls. An attacker must have valid administrative credentials and upload a malicious file to exploit this XML External Entity (XXE) vulnerability. No patch is currently available.
