IceWarp Webclient before 10.2.1 has a directory traversal vulnerability. This can result in loss of confidential data of IceWarp Mailserver and the operating system. Input passed via a certain parameter (_c to basic/index.html) is not properly sanitised and can therefore be exploited to browse the partition where IceWarp is installed (or the whole system) and read arbitrary files.
IceWarp Mail Server through 10.4.4 is prone to a local file inclusion vulnerability via webmail/calendar/minimizer/index.php?style=..%5c directory traversal.
Cross-site scripting (XSS) vulnerability for webdav/ticket/ URIs in IceWarp Mail Server 12.0.3 allows remote attackers to inject arbitrary web script or HTML.
Multiple directory traversal vulnerabilities in IceWarp Mail Server before 11.2 allow remote attackers to read arbitrary files via a (1) .. (dot dot) in the file parameter to a webmail/client/skins/default/css/css.php page or .../. (dot dot dot slash dot) in the (2) script or (3) style parameter to webmail/old/calendar/minimizer/index.php.
