Cross-Site Scripting in serve-index

Moderate severity GitHub Reviewed Published Oct 24, 2017 to the GitHub Advisory Database • Updated Nov 5, 2023

Package

npm serve-index (npm)

Affected versions

< 1.6.3

Patched versions

1.6.3

Description

Versions 1.6.2 and earlier of serve-index are affected by a cross-site scripting vulnerability. Because file and directory names are not escaped in the module's HTML output, a remote attacker that can influence file or directory names can launch a persistent cross-site scripting attack on the application.

Recommendation

Update to version 1.6.3 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.
