CVE-2023-38493 (GCVE-0-2023-38493)

Vulnerability from cvelistv5 – Published: 2023-07-25 20:51 – Updated: 2024-10-03 18:47

Title
Paths contain matrix variables bypass decorators
Summary
Armeria is a microservice framework Spring supports Matrix variables. When Spring integration is used, Armeria calls Spring controllers via `TomcatService` or `JettyService` with the path that may contain matrix variables. Prior to version 1.24.3, the Armeria decorators might not invoked because of the matrix variables. If an attacker sends a specially crafted request, the request may bypass the authorizer. Version 1.24.3 contains a patch for this issue.
