## Overview

A vulnerability in the web-based management interface of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker with administrative-level privileges to write arbitrary files on an affected device.

This vulnerability exists because the affected software does not properly validate directory traversal character sequences in a user-supplied file path during the upload process. An attacker could exploit this vulnerability by uploading a crafted file to the affected system. A successful exploit could allow the attacker to write files to an arbitrary location on the affected system.

## Affected

- `identity_services_engine >= 3.1.0, < 3.3.0`
- `identity_services_engine = 3.3.0`
- `identity_services_engine = 3.4.0`
- `identity_services_engine = 3.5.0`
- `identity_services_engine_passive_identity_connector >= 3.1.0, < 3.3.0`
- `identity_services_engine_passive_identity_connector = 3.3.0`
- `identity_services_engine_passive_identity_connector = 3.4.0`

## Remediation

Upgrade past the affected range:

- `identity_services_engine 3.3.0`
- `identity_services_engine_passive_identity_connector 3.3.0`
