Emerson DeltaV DCS versions 11.3.1, 12.3.1, 13.3.0, 13.3.1, R5 may allow non-administrative users to change executable and library files on the affected products.
DeltaV Versions 11.3.1, 12.3.1, 13.3.0, 13.3.1, and R5 is vulnerable due to improper path validation which may allow an attacker to replace executable files.
DeltaV Versions 11.3.1, 12.3.1, 13.3.0, 13.3.1, and R5 is vulnerable to a buffer overflow exploit through an open communication port to allow arbitrary code execution.
A Stack-based Buffer Overflow issue was discovered in Emerson Process Management ControlWave Micro Process Automation Controller: ControlWave Micro [ProConOS v.4.01.280] firmware: CWM v.05.78.00 and prior. A stack-based buffer overflow vulnerability caused by sending crafted packets on Port 20547 could force the PLC to change its state into halt mode.
An issue was discovered in Emerson DeltaV Easy Security Management DeltaV V12.3, DeltaV V12.3.1, and DeltaV V13.3. Critical vulnerabilities may allow a local attacker to elevate privileges within the DeltaV control system.
An issue was discovered in Emerson SE4801T0X Redundant Wireless I/O Card V13.3, and SE4801T1X Simplex Wireless I/O Card V13.3. DeltaV Wireless I/O Cards (WIOC) running the firmware available in the DeltaV system, release v13.3, have the SSH (Secure Shell) functionality enabled unnecessarily.
An XML External Entity (XXE) issue was discovered in Emerson Liebert SiteScan Web Version 6.5, and prior. An attacker may enter malicious input to Liebert SiteScan through a weakly configured XML parser causing the application to execute arbitrary code or disclose file contents from a server or connected network.
Emerson Process Management ROC800 RTU with software 3.50 and earlier, DL8000 RTU with software 2.30 and earlier, and ROC800L RTU with software 1.20 and earlier allows remote attackers to execute arbitrary commands via a TCP replay attack.
Emerson DeltaV 10.3.1, 11.3, 11.3.1, and 12.3 uses hardcoded credentials for diagnostic services, which allows remote attackers to bypass intended access restrictions via a TCP session, as demonstrated by a session that uses the telnet program.
