| Descripción | Hello team,
I have identified a Reflected Cross-Site Scripting (XSS) vulnerability in Vtiger CRM (version 6.4.0) that allows an attacker to bypass the current application filters. This vulnerability requires user interaction, as it is triggered when a victim clicks on a maliciously crafted link.
Technical Details
Vulnerable Parameter: _operation
Affected Endpoint: /modules/Mobile/index.php?
Vulnerability Type: Reflected XSS
Impact: An attacker can execute arbitrary JavaScript in the context of the victim’s session, potentially leading to session hijacking or other malicious actions.
Bypass Mechanism: The application does not adequately sanitize input, allowing JavaScript execution through an encoded payload.
Proof of Concept (PoC)
A crafted URL can be used to exploit this issue:
http://vmd39268.contaboserver.net:8080/modules/Mobile/index.php?_operation=%3Ca%20href=%20javascript%26colon;confirm(document.cookie)%3Eclick%20here
