Vulnerability Title
odt2spip < 4.4.0 OS Command Injection via Document Filename
Source: CVE Program / CVE List V5
Vulnerability Description
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. Attackers can embed shell metacharacters such as $(id) in a non-.odt filename, which survives insufficient sanitization in odt2spip_deplacer_fichier_upload() and LibreOffice::createCommand(), to achieve remote code execution as the web-server user during the LibreOffice conversion process.
