Vapor vulnerable to denial of service in HTTP Range Request of FileMiddleware

High severity GitHub Reviewed Published May 31, 2022 in vapor/vapor • Updated Jun 19, 2023

Package

swift github.com/vapor/vapor (Swift)

Affected versions

< 4.60.3

Patched versions

4.60.3

Description

Vapor is an HTTP web framework for Swift and middleware is a logic chain between the client and a Vapor route handler. FileMiddleware enables the serving of assets from the Public folder of a project to the client.

Vapor before 4.60.3 is vulnerable to denial of service due to an integer overflow when given invalid range headers while using FileMiddleware. This is patched in 4.60.3.

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.
