Siemens Simatic WinCC and PCS 7 SCADA system uses a hard-coded password, which allows local users to access a back-end database and gain privileges, as demonstrated in the wild in July 2010 by the Stuxnet worm, a different vulnerability than CVE-2010-2568.
Siemens SIMATIC WinCC 7.0 through SP3 and 7.2 allows remote attackers to read arbitrary WinCC station files via crafted packets.
