Executive Summary

This vulnerability exists in Cisco ISE and ISE-PIC and allows an unauthenticated, remote attacker to view sensitive information on the affected device.

It occurs because of improper authorization checks when accessing certain resources. An attacker can exploit this by sending specially crafted traffic to the device.

If successfully exploited, the attacker could gain access to sensitive information, including hashed credentials, which could be used in further attacks.

Compliance Impact

This vulnerability allows an unauthenticated, remote attacker to access sensitive information, including hashed credentials, due to improper authorization checks. Exposure of sensitive information can lead to non-compliance with data protection regulations such as GDPR and HIPAA, which require safeguarding personal and sensitive data against unauthorized access.

Organizations using affected Cisco ISE and ISE-PIC devices may face increased risk of data breaches, potentially violating requirements for confidentiality and data security mandated by these standards.

Impact Analysis

This vulnerability can impact you by exposing sensitive information on your Cisco ISE or ISE-PIC devices to unauthorized attackers.

Specifically, attackers could obtain hashed credentials, which might allow them to perform future attacks such as credential cracking or unauthorized access.

Because the vulnerability requires no authentication and can be exploited remotely, it poses a significant risk to the confidentiality of your system's data.
