DescriptionCVE.org

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.

AnalysisAI

Zip-slip path traversal in File Browser 2.63.6–2.63.16 allows a low-privileged user with upload permission to plant a POSIX backslash-named file that the archive builder incorrectly normalizes into a directory traversal sequence, enabling arbitrary file write on any victim who downloads and extracts the generated archive. The root cause is the server-side conversion of \ to / in archive entry names, which manufactures paths like ../../evil.sh from the legal POSIX filename ..\..\evil.sh. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV; however, the attack chain is straightforward for any user with upload access.
