Moderate
orange-cert-cc published GHSA-q2v9-qpmg-4qc4 Apr 19, 2022

Package

IOx (Cisco)

Affected versions

17.3.3

Patched versions

17.3(5)

Description

Overview

A vulnerability in the web-based Local Manager interface of the Cisco IOx application hosting environment could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based Local Manager interface of an affected device.

Impact

The attacker must have valid Local Manager credentials.This vulnerability is due to insufficient validation of user-supplied input by the web-based Local Manager interface.

Details

A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web interface or allow the attacker to access sensitive browser-based information.

Solution

Security patch

Upgrade to patched version (see above).

Workaround

There are no workarounds that address this vulnerability.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
