CVE-2021-26264 1 Emerson 2 Deltav Distributed Control System, Deltav Workstation 2025-04-17 6.1 Medium
A specially crafted script could cause the DeltaV Distributed Control System Controllers (All Versions) to restart and cause a denial-of-service condition.
CVE-2022-30260 1 Emerson 48 Deltav Distributed Control System Sq Controller, Deltav Distributed Control System Sq Controller Firmware, Deltav Distributed Control System Sx Controller and 45 more 2024-11-21 7.8 High
Emerson DeltaV Distributed Control System (DCS) has insufficient verification of firmware integrity (an inadequate checksum approach, and no signature). This affects versions before 14.3 of DeltaV M-series, DeltaV S-series, DeltaV P-series, DeltaV SIS, and DeltaV CIOC/EIOC/WIOC IO cards.
CVE-2022-29965 1 Emerson 49 Deltav Distributed Control System, Deltav Distributed Control System Sq Controller, Deltav Distributed Control System Sq Controller Firmware and 46 more 2024-11-21 5.5 Medium
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.
CVE-2022-29964 1 Emerson 48 Deltav Distributed Control System Sq Controller, Deltav Distributed Control System Sq Controller Firmware, Deltav Distributed Control System Sx Controller and 45 more 2024-11-21 5.5 Medium
The Emerson DeltaV Distributed Control System (DCS) controllers and IO cards through 2022-04-29 misuse passwords. WIOC SSH provides access to a shell as root, DeltaV, or backup via hardcoded credentials. NOTE: this is different from CVE-2014-2350.
CVE-2022-29963 1 Emerson 48 Deltav Distributed Control System Sq Controller, Deltav Distributed Control System Sq Controller Firmware, Deltav Distributed Control System Sx Controller and 45 more 2024-11-21 5.5 Medium
The Emerson DeltaV Distributed Control System (DCS) controllers and IO cards through 2022-04-29 misuse passwords. TELNET on port 18550 provides access to a root shell via hardcoded credentials. This affects S-series, P-series, and CIOC/EIOC nodes. NOTE: this is different from CVE-2014-2350.
CVE-2022-29962 1 Emerson 48 Deltav Distributed Control System Sq Controller, Deltav Distributed Control System Sq Controller Firmware, Deltav Distributed Control System Sx Controller and 45 more 2024-11-21 5.5 Medium
The Emerson DeltaV Distributed Control System (DCS) controllers and IO cards through 2022-04-29 misuse passwords. FTP has hardcoded credentials (but may often be disabled in production). This affects S-series, P-series, and CIOC/EIOC nodes. NOTE: this is different from CVE-2014-2350.
CVE-2022-29957 1 Emerson 1 Deltav Distributed Control System 2024-11-21 7.8 High
The Emerson DeltaV Distributed Control System (DCS) through 2022-04-29 mishandles authentication. It utilizes several proprietary protocols for a wide variety of functionality. These protocols include Firmware upgrade (18508/TCP, 18518/TCP); Plug-and-Play (18510/UDP); Hawk services (18507/UDP); Management (18519/TCP); Cold restart (18512/UDP); SIS communications (12345/TCP); and Wireless Gateway Protocol (18515/UDP). None of these protocols have any authentication features, allowing any attacker capable of communicating with the ports in question to invoke (a subset of) desired functionality.
