CyberRota Analysis

AI-Generated

File Browser versions 2.63.6 to 2.63.16 are vulnerable to a directory traversal attack due to improper handling of backslashes in filenames during archive creation, enabling users with upload permissions to insert malicious files that can escape the intended extraction directory. This vulnerability poses a risk of unauthorized file access and potential exploitation when other users extract the archives. Organizations using affected versions should prioritize upgrading to version 2.63.17 to mitigate this risk.

Original NVD Description

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. From 2.63.6 to 2.63.16, File Browser's archive builder uses strings.ReplaceAll(nameInArchive, "\", "/"), which turns a POSIX filename such as ..\..\evil.sh into the archive entry ../../evil.sh, allowing a user with upload permission to plant a backslash-named file that escapes the extraction directory when another user downloads and extracts the generated zip or tar archive. This issue is fixed in version 2.63.17.
