Szafir: XML External Entity (XXE) injection
Szafir and Szafir Weryfikująca, Polish electronic signature applications from Krajowa Izba Rozliczeniowa, process external entities in XML files. When a user signs or verifies a crafted XML file with an external DTD reference, an attacker can read arbitrary files from the victim's system. Exploitation requires the victim to open the file, for example one received by email or download, and no network service is exposed.
