Hello list!

I want to warn you about Brute Force 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 36 vulnerabilities in IFOBS: 2 BF and 34 XSS (in the 
first advisory there were 38 vulnerabilities).

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

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

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

Brute Force (WASC-11):

In login form of certificates console 
(http://site/ifobsClient/certmasterlogin.jsp) there is no protection against 
picking up password (captcha).

In forms of checking registration status and editing of registration profile 
there are no protection against picking up password (captcha). Both forms 
are at page http://site/ifobsClient/regclientmain.jsp (they also can be 
accessed by addresses 
http://site/ifobsClient/regclientmain.jsp?myaction=getloginformForStatus and 
http://site/ifobsClient/regclientmain.jsp?myaction=getloginformForEdit) and 
they use the same script.

Cross-Site Scripting (WASC-08):

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

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