Detailsinfo

A vulnerability, which was classified as critical, was found in Craft CMS up to 4.17.4/5.9.10. This affects the function replaceFile. The manipulation of the argument targetFilename with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as 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. This is going to have an impact on integrity, and availability. The summary by CVE is:

Craft CMS is a content management system (CMS). From version 4.0.0-RC1 to before version 4.17.5 and from version 5.0.0-RC1 to before version 5.9.11, the AssetsController->replaceFile() method has a targetFilename body parameter that is used unsanitized in a deleteFile() call before Assets::prepareAssetName() is applied on save. This allows an authenticated user with replaceFiles permission to delete arbitrary files within the same filesystem root by injecting ../ path traversal sequences into the filename. This could allow an authenticated user with replaceFiles permission on one volume to delete files in other folders/volumes that share the same filesystem root. This only affects local filesystems. This issue has been patched in versions 4.17.5 and 5.9.11.
