A vulnerability was found in Kingdee Cloud-Starry-Sky Enterprise Edition up to 8.2. It has been classified as problematic. Affected is the function BaseServiceFactory.getFileUploadService.deleteFileAction of the file K3Cloud\BBCMallSite\WEB-INF\lib\Kingdee.K3.O2O.Base.WebApp.jar!\kingdee\k3\o2o\base\webapp\action\FileUploadAction.class of the component IIS-K3CloudMiniApp. The manipulation of the argument filePath leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor recommends as a short-term measure to "[t]emporarily disable external network access to the Kingdee Cloud Galaxy Retail System or set up an IP whitelist for access control." The long-term remediation will be: "Install the security patch provided by the Starry Sky system, with the specific solutions being: i) Adding authentication to the vulnerable CMKAppWebHandler.ashx interface; ii) Removing the file reading function."
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.
