Summary

The odt2spip plugin for SPIP before 4.4.0 contains an OS command injection vulnerability that allows authenticated authors to execute arbitrary commands by uploading a document with a maliciously crafted filename through the document import form. Shell metacharacters such as $(id) in a non-.odt filename survive insufficient sanitization in odt2spip_deplacer_fichier_upload() and LibreOffice::createCommand(), achieving remote code execution as the web-server user during the LibreOffice conversion process.

Risk Assessment

An authenticated author can execute arbitrary system commands on the server, leading to full host compromise and data breach.

Recommendation

Upgrade the odt2spip plugin to version 4.4.0 or later, which properly neutralizes shell metacharacters in filenames.
