Symphony 2.2.3 - '/symphony/publish/images?filter' Cross-Site Scripting

text exploit Source: Exploit-DB
source: https://www.securityfocus.com/bid/50470/info

Symphony is prone to multiple SQL-injection vulnerabilities and multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data.

Exploiting these vulnerabilities could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

Symphony versions prior to 2.2.4 are vulnerable.
