Summary

Lumiverse before version 0.9.7 contains a command injection vulnerability in the SMB path handling function. When the primary toSmbPath method fails, the code uses an unvalidated basename in the smbclient script, allowing arbitrary command execution via injection of ';' separator or '!cmd' local escape.

Risk Assessment

An attacker can remotely execute arbitrary commands on the Lumiverse server, leading to full compromise of the application and potentially the entire system.

Recommendation

Immediately upgrade Lumiverse to version 0.9.7 or later, which includes a fix for this vulnerability.

Original NVD description (English source)

Lumiverse is a full-featured AI chat application. Prior to 0.9.7, when the primary toSmbPath(fullPath) call throws, the method falls back to a dirname/basename split and only validates the directory prefix. The basename is concatenated directly into the smbclient -c script without validation. smbclient interprets ; as a subcommand separator and !cmd as a local-shell escape that runs cmd on the host. A path whose directory component is clean but whose basename contains "; !<cmd>; echo " achieves arbitrary command execution on the Lumiverse server. This vulnerability is fixed in 0.9.7.
