Multiple cross-site scripting (XSS) vulnerabilities in SibSoft CommuniMail 1.2 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the list_id parameter in mailadmin.cgi and (2) the form_id parameter in templates.cgi.

SibSoft Xfilesharing through 2.5.1 allows cgi-bin/up.cgi arbitrary file upload. This can be combined with CVE-2019-18951 to achieve remote code execution via a .html file, containing short codes, that is served over HTTP.

SibSoft Xfilesharing through 2.5.1 allows op=page&tmpl=../ directory traversal to read arbitrary files.
