CVE-2011-4859
HighSummary
Moduł Ethernet Quantum firmy Schneider Electric, używany w różnych modułach, posiada twardo zakodowane hasła dla wielu kont użytkowników. To ułatwia zdalnym atakującym uzyskanie dostępu do systemu przez porty TELNET, Windriver Debug lub FTP.
Risk Assessment
Wykorzystanie twardo zakodowanych haseł stwarza poważne ryzyko dla bezpieczeństwa, umożliwiając nieautoryzowany dostęp do krytycznych systemów. Organizacje mogą być narażone na ataki, które mogą prowadzić do utraty danych lub zakłócenia działania systemów.
Recommendation
Zaleca się usunięcie twardo zakodowanych haseł i wdrożenie silnych, unikalnych haseł dla wszystkich kont użytkowników. Należy również rozważyć ograniczenie dostępu do portów TELNET, Windriver Debug i FTP.

Original NVD description (English source)
The Schneider Electric Quantum Ethernet Module, as used in the Quantum 140NOE771* and 140CPU65* modules, the Premium TSXETY* and TSXP57* modules, the M340 BMXNOE01* and BMXP3420* modules, and the STB DIO STBNIC2212 and STBNIP2* modules, uses hardcoded passwords for the (1) AUTCSE, (2) AUT_CSE, (3) fdrusers, (4) ftpuser, (5) loader, (6) nic2212, (7) nimrohs2212, (8) nip2212, (9) noe77111_v500, (10) ntpupdate, (11) pcfactory, (12) sysdiag, (13) target, (14) test, (15) USER, and (16) webserver accounts, which makes it easier for remote attackers to obtain access via the (a) TELNET, (b) Windriver Debug, or (c) FTP port.
