IceWarp WebClient DC2 - Update 2 Build 9 (13.0.2.9) was discovered to contain a SQL injection vulnerability via the search parameter at /webmail/server/webmail.php.
Cross Site Scripting (XSS) in Webmail Calender in IceWarp WebClient 10.3.5 allows remote attackers to inject arbitrary web script or HTML via the "p4" field.
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 (script to basic/minimizer/index.php) 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.
