DescriptionGitHub Advisory

Pode is a Cross-Platform PowerShell web framework for creating REST APIs, Web Sites, and TCP/SMTP servers. From 2.4.0, to before 2.13.0, when requesting content from a Static Route, it was possible to request paths such as http://localhost:8080/c:/Windows/System32/drivers/etc/hosts and have the contents returned. This vulnerability is fixed in 2.13.0.

AnalysisAI

Path traversal in Pode PowerShell web framework versions 2.4.0 through 2.12.x allows high-privileged authenticated users to read arbitrary files from the server filesystem via crafted static route requests. An attacker with high privilege can request paths like http://localhost:8080/c:/Windows/System32/drivers/etc/hosts to retrieve sensitive file contents. The vulnerability is fixed in version 2.13.0.
