Open Redirect in serve-static

Low severity GitHub Reviewed Published Aug 31, 2020 to the GitHub Advisory Database • Updated Jan 9, 2023

Package

npm serve-static (npm)

Affected versions

< 1.6.5
>= 1.7.0, < 1.7.2

Patched versions

1.7.2
1.7.2

Description

Versions of serve-static prior to 1.6.5 ( or 1.7.x prior to 1.7.2 ) are affected by an open redirect vulnerability on some browsers when configured to mount at the root directory.

Proof of Concept

A link to http://example.com//www.google.com/%2e%2e will redirect to //www.google.com/%2e%2e

Some browsers will interpret this as http://www.google.com/%2e%2e, resulting in an external redirect.

Recommendation

Version 1.7.x: Update to version 1.7.2 or later.
Version 1.6.x: Update to version 1.6.5 or later.

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.
