Description

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.

Affected products

IceWarp Webclient: from 10.0 before 10.2.1 — fixed in 10.2.1

How to fix

Upgrade to a fixed version: IceWarp Webclient 10.2.1. Check the vendor advisory for mitigations.
