Technical ContextAI · show details

This vulnerability is classified under CWE-327. The Emerson DeltaV Distributed Control System (DCS) controllers and IO cards through 2022-04-29 misuse passwords. Access to privileged operations on the maintenance port TELNET interface (23/TCP) on M-series and SIS (CSLS/LSNB/LSNG) nodes is controlled by means of utility passwords. These passwords are generated using a deterministic, insecure algorithm using a single seed value composed of a day/hour/minute timestamp with less than 16 bits of entropy. The seed value is fed through a lookup table and a series of permutation operations resulting in three different four-character passwords corresponding to different privilege levels. An attacker can easily reconstruct these passwords and thus gain access to privileged maintenance operations. NOTE: this is different from CVE-2014-2350. Affected products include: Emerson Deltav Distributed Control System, Emerson Deltav Distributed Control System Sq Controller Firmware, Emerson Deltav Distributed Control System Sx Controller Firmware, Emerson Se4002S1T2B6 High Side 40-Pin Mass I\/O Terminal Block Firmware, Emerson Se4003S2B4 16-Pin Mass I\/O Terminal Block Firmware. Version information: through 2022.
