Path Traversal in cordova-plugin-ionic-webview

High severity GitHub Reviewed Published Feb 12, 2019 to the GitHub Advisory Database • Updated Jan 9, 2023

Package

npm cordova-plugin-ionic-webview (npm)

Affected versions

< 2.2.0

Patched versions

2.2.0

Description

Versions of cordova-plugin-ionic-webview prior to 2.2.0 are vulnerable to Path Traversal, allowing attackers access to OS local files that should be inaccessible by third-party applications. The package launches a webserver listening on http://localhost:8080 without restricting access of the app itself, thus escaping the iOS application sandbox and accessing local files.

Recommendation

Upgrade to version 2.2.0

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.
