The "Sparkassen-Finanzgruppe" with a transaction volume of over 3.300 billion euro is one of the largest banks for private customers in germany. Many local member-banks of the group use the online banking portal provided by sfze (http://www.sfze.de/), a subsidiary company of Sparkassen-Finanzgruppe.
After having published the XSS vulnerability on various sparkassen online banking sites 24 hours ago, I received feedback from the company sfze.
They informed me that the DO NOT operate the online banking portal which is affected by the vulnerability.
I therefore have to apologize: It was not my intention to blame the wrong company. sfze has nothing to do with the XSS vulnerability on german online-banking sites.
To say this clear: I do not know definitely which subsidiary company of Sparkassen-Finanzgruppe is responsible for the online banking portal, and is able to fix this problem.
