Technical details
The vulnerability is a reflected XSS in the synchro_import.php script caused by improper sanitization of the data_source_id query parameter. The parameter was previously processed with 'raw_data' mode, allowing script injection; the fix sanitizes it as an integer value using utils::ENUM_SANITIZATION_FILTER_INTEGER. Attack requires network access to the iTop instance and low-level privileges (authentication) plus user interaction (victim clicking a malicious link). An attacker can execute arbitrary JavaScript in the victim's browser within the security context of the iTop application, potentially accessing sensitive IT infrastructure data. Patches are available in versions 3.2.3 and 3.3.0.
