Subject: CSRF and XSS vulnerabilities in IFOBS

Hello list!

I want to warn you about Cross-Site Request Forgery and Cross-Site Scripting
vulnerabilities in system IFOBS.

IFOBS - it's Internet-banking system, which is widespread and particularly
it's used by large number of Ukrainian banks.

These are the next 35 vulnerabilities in IFOBS: 1 CSRF and 34 XSS (in the
first two advisories there were 74 vulnerabilities).

-------------------------
Affected products:
-------------------------

Vulnerable are all versions of IFOBS. The developers have ignored and not
fixed these vulnerabilities (all holes from three advisories).

Details:
----------

Cross-Site Request Forgery (WASC-09):

Lack of protection against Brute Force in login form
(http://site/ifobsClient/loginlite.jsp), mentioned earlier, also leads to
possibility of conducting of CSRF attack, which I wrote about in the article
Attacks on unprotected login forms
(http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2011-April/007773.html).
It allows to conduct remote login into account (for conducting of attacks on
vulnerabilities inside account). It also can be used for automated login
into account, phishing and other automated attacks.

Cross-Site Scripting (WASC-08):

http://site/ifobsClient/regclientalerts.jsp?labelname=%3Cscript%3Ealert(document.cookie)%3C/script%3E

POST request at page http://site/ifobsClient/regclientform.jsp in
parameters: secondName, firstName, thirdName, BirthDay, BirthMonth,
BirthYear, address, livePlace, passportSerialpassportNumber, PassportDay,
PassportMonth, PassportYear, passportIssueAgency,
tempDocSerialtempDocNumber, tempDocSerial, DocMonth, DocYear, idCodeNumber,
CodeRegDay, CodeRegMonth, CodeRegYear, idCodeRegPlace, phone, email,
pmcountry, pmnumber, keyword, password, bankAddress, bankContacts,
typeclient.

Exploits for the first five vulnerabilities ((in parameters secondName,
firstName, thirdName, BirthDay, BirthMonth):
