In Schneider Electric Triconex Tricon MP model 3008 firmware versions 10.0-10.4, when a system call is made, registers are stored to a fixed memory location. Modifying the data in this location could allow attackers to gain supervisor-level access and control system states.

On Schneider Electric ConneXium Tofino Firewall TCSEFEA23F3F22 before 03.23, TCSEFEA23F3F20/21, and Belden Tofino Xenon Security Appliance, an arbitrary firmware image can be loaded because firmware signature verification (for a USB stick) can be bypassed. NOTE: this issue exists because of an incomplete fix of CVE-2017-11400.

An improper access control vulnerability exists in Schneider Electric's U.motion Builder software versions 1.2.1 and prior in which an improper handling of the system configuration can allow an attacker to execute arbitrary code under the context of root.

An Incorrect Default Permissions issue was discovered in Schneider Electric Wonderware InduSoft Web Studio v8.0 Patch 3 and prior versions. Upon installation, Wonderware InduSoft Web Studio creates a new directory and two files, which are placed in the system's path and can be manipulated by non-administrators. This could allow an authenticated user to escalate his or her privileges.

A CWE-269: Improper Privilege Management vulnerability exists that could allow elevated functionality when guessing credentials. Affected Products: Acti9 PowerTag Link C (A9XELC10-A) (V1.7.5 and prior), Acti9 PowerTag Link C (A9XELC10-B) (V2.12.0 and prior)

CWE-327: Use of a Broken or Risky Cryptographic Algorithm vulnerability exists that could cause denial of service, device reboot, or an attacker gaining full control of the relay when a specially crafted reset token is entered into the front panel of the device.

Buffer overflow in the UnitelWay Windows Device Driver, as used in Schneider Electric Unity Pro 6 and earlier, OPC Factory Server 3.34, Vijeo Citect 7.20 and earlier, Telemecanique Driver Pack 2.6 and earlier, Monitor Pro 7.6 and earlier, and PL7 Pro 4.5 and earlier, allows local users, and possibly remote attackers, to execute arbitrary code via an unspecified system parameter.

A CWE-269 Improper Privilege Management vulnerability exists in EcoStruxureª Operator Terminal Expert runtime (Vijeo XD) that could cause privilege escalation on the workstation when interacting directly with a driver installed by the runtime software of EcoStruxureª Operator Terminal Expert.

An issue has been discovered on the Belden Hirschmann Tofino Xenon Security Appliance before 03.2.00. An incomplete firmware signature allows a local attacker to upgrade the equipment (kernel, file system) with unsigned, attacker-controlled, data. This occurs because the appliance_config file is signed but the .tar.sec file is unsigned.
