A vulnerability, which was classified as problematic, was found in Pragyan CMS up to 3.0 (Content Management System). Affected is an unknown code in the library download.lib.php. The manipulation of the argument fileget 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:
