Detailsinfo

A vulnerability, which was classified as critical, has been found in lumen-oss luanox up to 0.1.0. This issue affects an unknown part of the component Phoenix Runtime File Handler. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Luanox is a module host for Lua packages. Prior to 0.1.1, a file traversal vulnerability can cause potential denial of service by overwriting Phoenix runtime files. Package names like ../../package are not properly filtered and pass the validity check of the rockspec verification system. This causes the uploaded file to be stored at the relative path location. If planned carefully, this could overwrite a runtime file and cause the website to crash. This vulnerability is fixed by 0.1.1.
