Emerson Electric's Proficy Machine Edition Version 9.00 and prior is vulenrable to CWE-284 Improper Access Control, and stores project data in a directory with improper access control lists.

Emerson Electric's Proficy Machine Edition Version 9.00 and prior is vulenrable to CWE-347 Improper Verification of Cryptographic Signature, and does not properly verify compiled logic (PDT files) and data blocks data (BLD/BLK files).

Emerson Electric's Proficy Machine Edition Version 9.00 and prior is vulnerable to CWE-345 Insufficient Verification of Data Authenticity, and can display logic that is different than the compiled logic.

Emerson Electric's Proficy Machine Edition Version 9.80 and prior is vulnerable to CWE-29 Path Traversal: '\..\Filename', also known as a ZipSlip attack, through an upload procedure which enables attackers to implant a malicious .BLZ file on the PLC. The file can transfer through the engineering station onto Windows in a way that executes the malicious code.

The Emerson ControlWave 'Next Generation' RTUs through 2022-05-02 mishandle firmware integrity. They utilize the BSAP-IP protocol to transmit firmware updates. Firmware updates are supplied as CAB archive files containing a binary firmware image. In all cases, firmware images were found to have no authentication (in the form of firmware signing) and only relied on insecure checksums for regular integrity checks.

The Emerson ROC and FloBoss RTU product lines through 2022-05-02 perform insecure filesystem operations. They utilize the ROC protocol (4000/TCP, 5000/TCP) for communications between a master terminal and RTUs. Opcode 203 of this protocol allows a master terminal to transfer files to and from the flash filesystem and carrying out arbitrary file and directory read, write, and delete operations.

Emerson OpenBSI through 2022-04-29 mishandles credential storage. It is an engineering environment for the ControlWave and Bristol Babcock line of RTUs. This environment provides access control functionality through user authentication and privilege management. The credentials for various users are stored insecurely in the SecUsers.ini file by using a simple string transformation rather than a cryptographic mechanism.

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.

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.

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.
