The manipulation of the argument file 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. The summary by CVE is:

Open STA Manager 2.3 contains a path traversal vulnerability that allows authenticated users to download arbitrary files by manipulating the file parameter. Attackers can send GET requests to modules/backup/actions.php with op=getfile and traverse directories using ../ sequences to access sensitive system files.
