Detailsinfo

A vulnerability, which was classified as problematic, has been found in OpenRefine simile-butterfly up to 1.2.5. Affected by this issue is the function java.net.URL of the component URL Handler. The manipulation with an unknown input leads to a absolute path traversal vulnerability. Using CWE to declare the problem leads to CWE-36. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The OpenRefine fork of the MIT Simile Butterfly server is a modular web application framework. The Butterfly framework uses the `java.net.URL` class to refer to (what are expected to be) local resource files, like images or templates. This works: "opening a connection" to these URLs opens the local file. However, prior to version 1.2.6, if a `file:/` URL is directly given where a relative path (resource name) is expected, this is also accepted in some code paths; the app then fetches the file, from a remote machine if indicated, and uses it as if it was a trusted part of the app's codebase. This leads to multiple weaknesses and potential weaknesses. An attacker that has network access to the application could use it to gain access to files, either on the the server's filesystem (path traversal) or shared by nearby machines (server-side request forgery with e.g. SMB). An attacker that can lead or redirect a user to a crafted URL belonging to the app could cause arbitrary attacker-controlled JavaScript to be loaded in the victim's browser (cross-site scripting). If an app is written in such a way that an attacker can influence the resource name used for a template, that attacker could cause the app to fetch and execute an attacker-controlled template (remote code execution). Version 1.2.6 contains a patch.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2024-47883 since 10/04/2024. The exploitation is known to be easy. The attack may be launched remotely. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading to version 1.2.6 eliminates this vulnerability. Applying the patch 537f64bfa72746f8b21d4bda461fad843435319c is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
