Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where 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. In Pimcore/pimcore, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact It was observed that the `/admin/misc/script-proxy` API endpoint accessible by an authenticated administrator user and is vulnerable arbitrary JavaScript, CSS file read via the "scriptPath" and "scripts" parameters. The "scriptPath" parameter is not sanitized properly and is vulnerable to path traversal attack. Any JavaScript/CSS file from the application server can be read by specifying sufficient number of "../" patterns to go out from the application webroot followed by path of the folder where the file is located in the "scriptPath" parameter and the file name in the "scripts" parameter. The JavaScript file is successfully read only if the web application has read access to it. ### Patches Update to version 10.5.21 or apply this patch manually https://github.com/pimcore/pimcore/commit/1d128404eddf4beb560d434437347da7aea059eb.patch ### Workarounds Apply patch https://github.com/pimcore/pimcore/commit/1d128404eddf4beb560d434437347da7aea059eb.patch manually. ### References https://github.com/pimcore/pimcore/pull/14959
