[OpenSER-Users] sanitizing sip requests

Hi all, I came across a security alert that basically embeds javascript in the display name of the From to initiate cross-site-scripting (XSS) attacks. Here is an example: From: "<script>alert('hack')</script>""user" <sip:user at domain.com <https://lists.grok.org.uk/mailman/listinfo/full-disclosure>>;tag=002a000c Grammatically , I don't see an issue with this. However, under the right circumstances this could get ugly. Do you see value in having openser take a proactive role to detect these and reject calls? Or is this outside the scope of what a proxy should be doing (leave it to the UA to sanitize) ? Looking to get your thoughts- -will
