An authenticated user can manipulate the file parameter to navigate above the intended directory and reference arbitrary files on the device\u2019s underlying filesystem. Because the Perl file\u2011handling routine does not sanitize the input, the backup endpoint returns a success status for existing files and a failure status for non\u2011existing files, allowing the attacker to confirm the presence of files.

The EPSS probability is less than 1\u202f%, suggesting that while the vulnerability can be exploited, it is not among the most frequently attacked weaknesses. The flaw is not listed in the CISA KEV catalog, and no public exploits have been reported.
