Detailsinfo

A vulnerability, which was classified as critical, was found in Knowage up to 8.1.7. Affected is some unknown functionality of the file _/knowage/restful-services/dossier/importTemplateFile_ of the component Template Handler. The manipulation of the argument _templateName_ 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 confidentiality. CVE summarizes:

Knowage is the professional open source suite for modern business analytics over traditional sources and big data systems. The endpoint `_/knowage/restful-services/dossier/importTemplateFile_` allows authenticated users to download template hosted on the server. However, starting in the 6.x.x branch and prior to version 8.1.8, the application does not sanitize the `_templateName_ `parameter allowing an attacker to use `*../*` in it, and escaping the directory the template are normally placed and download any file from the system. This vulnerability allows a low privileged attacker to exfiltrate sensitive configuration file. This issue has been patched in Knowage version 8.1.8.
