Ruby · Wicked · CVE-2013-4413
**Name of the Vulnerable Software and Affected Versions**
Wicked gem versions prior to 1.0.1
**Description**
The issue allows remote attackers to read arbitrary files via a %2E%2E%2F (encoded dot dot slash) in the step, due to a directory traversal vulnerability in controller/concerns/render redirect.rb. An attacker can send a specially-crafted URL request containing %2E%2E%2F directory traversal sequences to read arbitrary files on the system.
**Recommendations**
For Wicked gem versions prior to 1.0.1, update to version 1.0.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the `render redirect.rb` file in the `controller/concerns` directory to minimize the risk of exploitation. Avoid using the `%2E%2E%2F` sequence in URL requests to the affected endpoint until the issue is resolved.
