Software Description

Kayako Support Suite is a HelpDesk system.

Vulnerability Description

Positive Technologies Research Team discovered Local File Inclusion (LFI) vulnerabilities in Kayako Support Suite.

A vulnerable function unset() allows attackers to overwrite an arbitrary global and not overridden variable, which can particularly result in LFI. If a user has write access to the DBMS tables, then he/she can add the necessary field and cause a LFI.

Examples:

If a table cron contains the following fields:
cronid module name
7 m1 task1

Then an attacker can cause a LFI:
http://site/support/cron/index.php?_t=task1&_MODULES[m1]=[LOCAL INCLUDE]&-1575220259=1

Solution

Update to latest version.
