Technical description

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.

Remediation

Check the references section for vendor advisories and patches from schneider-electric. Update quantum_ethernet_module_140cpu65150 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
