## Affected

- facileManager: fixed in 6.0.4

## Description

facileManager is a modular suite of web apps built with the sysadmin in mind. Prior to 6.0.4 , a reflected XSS occurs when an application receives data from an untrusted source and uses it in its HTTP responses in a way that could lead to vulnerabilities. It is possible to inject malicious JavaScript code into a URL by adding a script in a parameter. This vulnerability was found in the fmDNS module. The parameter that is vulnerable to an XSS attack is log_search_query. This vulnerability is fixed in 6.0.4.
