Hello list!

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

it's used by large number of Ukrainian banks.

These are the first 38 vulnerabilities in IFOBS: 2 BF and 36 XSS.

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