In iTop through 2.6.0, an XSS payload can be delivered in certain fields (such as icon) of the XML file used to build the dashboard. This is similar to CVE-2015-6544 (which is only about the dashboard title).
In Combodo iTop 2.2.0 through 2.6.0, if the configuration file is writable, then execution of arbitrary code can be accomplished by calling ajax.dataloader with a maliciously crafted payload. Many conditions can place the configuration file into a writable state: during installation; during upgrade; in certain cases, an error during modification of the file from the web interface leaves the file writable (can be triggered with XSS); a race condition can be triggered by the hub-connector module (community version only from 2.4.1 to 2.6.0); or editing the file in a CLI.
Command injection vulnerability in Combodo iTop 2.4.1 allows remote authenticated administrators to execute arbitrary commands by changing the platform configuration, because web/env-production/itop-config/config.php contains a function called TestConfig() that calls the vulnerable function eval().
