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.

server/webmail.php in IceWarp WebMail in IceWarp Mail Server before 10.3.3 allows remote attackers to read arbitrary files, and possibly send HTTP requests to intranet servers or cause a denial of service (CPU and memory consumption), via an XML external entity declaration in conjunction with an entity reference.
IceWarp WebMail in IceWarp Mail Server before 10.3.3 allows remote attackers to obtain configuration information via a direct request to the /server URI, which triggers a call to the phpinfo function.
Multiple cross-site scripting (XSS) vulnerabilities in IceWarp eMail Server and WebMail Server before 9.4.2 allow remote attackers to inject arbitrary web script or HTML via (1) the body of a message, related to the email view and incorrect HTML filtering in the cleanHTML function in server/inc/tools.php; or the (2) title, (3) link, or (4) description element in an RSS feed, related to the getHTML function in server/inc/rss/item.php.
